GM Service Technical College (GM STC)

The GM STC works in conjunction with GM’s Center of Learning to eliminate redundant courses and unify the service technical training curriculum. Through its blended media approaches and high quality instructional design, GM STC helps to develop the service technician’s knowledge and skills while reducing time away from dealerships. GM’s customers benefit by knowing that the service technician has the background and experience to repair the vehicle correctly the first time.


This catalog from GM STC is intended for use by professional, qualified service technicians. Attempting repairs or service without the appropriate training, tools, and equipment could cause injury to you or others and potentially damage the vehicle or cause the vehicle to operate improperly. Proper vehicle service and repair are important to the safety of the service technician and to the safe, reliable operation of all motor vehicles.
Please be advised that all information in this catalog is the latest data available at the time of publication. GM STC reserves the right to make product or publication changes, at any time, without notice. New product information will be introduced as it becomes available in the media mix best suited to present the product. Be sure to check www.centerlearning.com for the latest information.

Training Overview

GM STC Service Technician Training

Training Goals

GM STC helps service technicians achieve the highest level of customer satisfaction in dealer service by structuring their training around a standard performance-based curriculum.

The curriculum provides a blended approach to training, dividing training between in-dealership and off-site locations. With the right mix of training methods, a growing number of technicians are able to demonstrate they are ready to “Fix it Right the First Time!”

Improved service quality leads to improved customer satisfaction and loyalty to the dealership and the product; improved customer satisfaction also helps the dealer achieve long-term profitability.

Dealer Benefits

By actively participating in the GM STC training program, dealers experience the following benefits:

  • More in-dealership training that requires service technicians to spend less time away from the dealership
  • A training website (www.centerlearning.com) that allows versatile, on-demand training management with a convenient “Path to 100% STS” link, training histories, ASE certification status integration, and training reports, among other features
  • Improved customer satisfaction and loyalty, based on more effective technician performance
  • Access to skilled entry-level automotive service technicians who graduate with GM STC course credits from the GM Automotive Service Educational Program (GM ASEP), the Shifting Gears Automotive Technician Training program, and the GM Technician Career Training program
  • Access to the GM Service Technical Automotive Readiness Training (GM START) program, which helps GM dealers recruit and retain service technicians by offering fundamental training in automotive technology

Service Technician Benefits

By participating in the GM STC training program, service technicians experience the following benefits:

  • Knowledge and skills to “Fix it Right the First Time!”
  • Faster professional development through the elimination of training redundancy
  • Focused training and career development provided by the “Path to 100% STS” link for required courses
  • Access to a performance-based curriculum that requires sufficient competency
  • Modular training to accommodate the technicians’ schedules

Performance-Based Curriculum

The GM STC performance-based curriculum offers training courses across Chevrolet, Buick, GMC, and Cadillac brands. To receive credit for a course, service technicians must demonstrate competency in all applicable course components, which may include web-based, VOD, VCT, and GM Service Know-How Emerging Issues seminars.

If a service technician does not demonstrate sufficient competency, they will be required to review or retake the course component until competency is obtained.

  • For web-based components, content-specific review is built into the training, with service technicians required to review until they obtain a score of 100% on test items.
  • For Virtual Classroom Training (VCT) components and GM Service Know-How Emerging Issues seminars, service technicians are required to retake the entire component until they obtain a score of 80% or better.
  • For Virtual Instructor-Led Training (V-ILT), Self-Study, and Performance Instructor-Led Training (P-ILT) course components, only the component that was not successfully completed needs to be retaken. If a technician passes both the V-ILT and Self-Study but fails to demonstrate sufficient competency in the P-ILT, they only need to retake the P-ILT.
  • For GM Service Know-How Video On Demand and videos, service technicians are required to view the video and take the test via www.centerlearning.com until they obtain a score of 80% or better.

The goal of the performance-based curriculum is to provide a path for service technicians to meet the requirements for GM’s Dealer Divisional Service Training Standards (STS) (for example, become Division Certified) and GM Master Technician Certification (MTC). The curriculum is divided into certification areas covering cars and light-duty trucks.

The 17 curriculum areas are:

*Training and certification is offered through GM-approved suppliers and not through GM STC.

Dealer Divisional STS Courses

Dealer Divisional STS Courses

Service technicians need STS courses to service the models that their dealerships sell. These courses are listed on their Learning Paths on the Center of Learning and in this catalog under the Bronze, Silver, and Gold categories. Service technicians are encouraged to take courses in order, from the top of the Learning Path to the bottom. This order best prepares the service technician for each successive course.
Future Bronze, Future Silver, and Future Gold courses will become STS required courses next year and are listed in order to prepare technicians and give them a chance to complete them early.

GM Master Technician
Certification Courses

GM Master Technician Certification Courses

GM MTC courses are represented in each Learning Path under the MTC category. This includes the final activity for the Learning Path, completing taking the Certification Assessment and earning the MTC (if they have the corresponding ASE Certification).

Supplemental Courses

Supplemental Courses

Supplemental courses provide additional content to enhance the service technician’s knowledge and skills but are not part of the MTC or Dealer Divisional STS requirements. Some of these courses may become an STS requirement in the future. Note that not all certification areas have supplemental courses.

The certification areas are made up of three types of courses:

  • Those required for the dealership to meet Dealer Divisional STS and for the service technician to become GM STC Division Certified.
  • Those required for the service technician to achieve GM Master Technician Certification (MTC).
  • Those that provide supplemental content to enhance the service technician’s knowledge and skills but are not part of GM MTC or the Dealer Divisional STS.

Blended Learning Media Mix Overview and Course Components

Center of Learning training is available at the dealership through a variety of media.

GM STC courses have evolved from traditional instructor-led to blended learning with more flexible delivery methods while emphasizing performance-based outcomes. This approach better supports service technician training by offering the appropriate media mix for the needed training in the 21st century.
The media mix includes, but is not exclusive to, Web-Based Training (WBT), Virtual Classroom Training (VCT), Video On-Demand (VOD), Performance Support Objects (PSO), and the Video Resource Library. This media mix allows service technicians to improve their product knowledge and advance their repair and diagnostic skills while spending less time away from the dealership.

Courses can also be accessed via a tablet; just look for this symbol. GM STC offers two modes of training:

  • Asynchronous training, also known as self-paced training, doesn’t require learners and instructor/s to be online or in person at the same time for instruction.
  • Synchronous training requires both learners and instructor/s to be present at the same time for instruction.

GM STC also offers a number of Accessibility options to help accommodate those that may need them. Review each type of training below to understand the different options available. If additional assistance is needed that is not accommodated by the information below, please reach out to the Help Desk and/or Training Center (depending on the type of training that accommodations are needed for) in a timely manner before the class session, so proper accommodations can be made.

Web-Based Training

Web-based course components are self-paced training. Instruction is delivered over the Internet and is just-in-time, specific, job-focused, and practical. Web- based appeals to a broad range of learning styles and is multi-sensory, meaning that instruction is presented through voice-over narration, text, graphics, and animation. Service technicians have the option to turn off the voice-over narration and display the narration script instead. Web-based training allows service technicians to review sections of the course as many times as needed to get comfortable with the content. Although an estimated training time is indicated for each web-based course component, service technicians learn at a pace best suited to their individual needs. Course progress is automatically bookmarked, allowing service technicians to log in and resume a course on any Internet-ready computer at their convenience.

Each course is divided into a number of modules which are then sub-divided into lessons. When a service technician completes a lesson or a module, he may continue on through the course or exit then return to the point at which he stopped at a later time. Enhancements have been made to the testing methodology for web-based modules. Upon starting a modularized course, the technician will not see any difference until he completes the first module. Upon completion of the module, the technician will be presented with a module test to complete.

This is done to ensure that all learning objectives are tested immediately after the content is presented to the technician. Technicians no longer have to take and pass a course test at the end of the training, thus saving additional time. The module test must be passed at 100 percent in order to receive credit.

GM STC’s Web Based Training provides on-screen text with the option of audio narration. A course script is available within the course settings themselves in the upper right-hand corner. Most often the script box will match the on screen text but if the narration is different in any way, the script box will match the spoken word.

Interactive Video

Interactive Video is a media solution that leverages the engaging production qualities of traditional video and adds in the user-involvement technology of HTML5 and web-based training. This maximizes interactivity and enables the technician to absorb the learning content at his own pace.

Interactive video courses end with a W (for web-based) in the course number; for example, Battery Electric Vehicle Introduction (18430.05W2).

Virtual Classroom Training (VCT)

This live, Internet-based training requires no special software although a headset equipped with a microphone is required to participate in the training. Virtual Classroom Training (VCT) provides live access for “on the spot” question-and-answer opportunities. Participants must complete the prerequisite course(s) prior to enrolling in any of these courses. After completing the prerequisite course, participants may enroll in any VCT course up to thirty minutes prior to the course start time.

Courses are delivered in a modular format with a duration of approximately two hours for each session. Post-test questions
are displayed at the end of each session. Technicians are allowed 20 minutes to complete the post-test, after which it will be closed.

Once the course component is completed, testing is accomplished via the post-test administered over the system. Service technicians’ answers are then tabulated, and their training records and Learning Paths are updated accordingly within 48 hours.

VCT Technician Guides are available to all participants and can be downloaded on the course details page within the Center of Learning. These comprehensive Guides cover the topics discussed in the course. If a video exists as part of a VCT course, the transcript of the video’s audio will be included in the course’s Technician Guide. Take note that some variation will occur during the live event that the Guide may not cover. The VCT platform also allows users to enlarge the viewing window with a Full Screen setting.

VCT courses end with a D in the course number; for example, Engines: New and Updates for RPOs LT4 and L0A (16440.19D).

Performance Support Object (PSO)

PSOs contain key points derived from selected web-based, online instructor-led, and Instructor-Led courses that reinforce training content and focus on how to perform certain job-related tasks.

Notification of a PSO will be emailed directly to the participant approximately two weeks after a course completion. PSOs can also be found on the Center of Learning, within the Resources tab.

Video On Demand (VOD)

Video On Demand course components offer service technicians the ability to view previously recorded content at any time. All Service Know-How Seminars are available for viewing on www.centerlearning.com.

With this VOD capability, service technicians can review video course material as needed. VOD content may be viewed in several ways:
From the Catalog page, type the course number or name in the search box.
From the home page, select a Learning Path, find it, and then select Launch.

All testing for GM Service Know-How videos is accomplished through www.centerlearning.com. Service technicians receive credit for the video components by successful completing appropriate post-tests available.
VOD content has a transcript that can be downloaded which contains the exact text of the audio in the video. These transcripts are located within the Technician Guides for each course. These Guides are found on the course details page on the Center of Learning.

VOD courses end with a V in the course number; for example, 8L90 Automatic Transmission Unit Repair (17041.70V).

Virtual and Performance Instructor-Led Training

An alternative to taking traditional hands-on instructor-led training, is the Virtual and Performance Instructor-Led Training (V/P-ILT). Each V/P-ILT is a series of three course components, that, once completed, provide credit for the hands-on requirement for the course. This means technicians can take the V/P-ILT course series instead of taking the traditional hands-on course to earn STS credit in their learning paths.

The three components that make up a V/P-ILT are Virtual Instructor-Led Training (V-ILT), a self-study worksheet with an associated posttest, and a Performance Instructor-Led Training (P-ILT) component. The V-ILT, Self-Study worksheet and posttest are completed without traveling to a GM training center. The P-ILT hands-on component is streamlined in order to reduce your time away from the dealer. The V-ILT component provides an open forum, instructor-led discussion. The self-study allows technicians to research and learn on their own, at their own pace. Finally the P-ILT is a streamlined, performance based course that focuses on validating skills.

To enroll, find the V-ILT in your learning path, or search for the course directly using the Catalog in Center of Learning. V-ILT course numbers end in a “D”. Once enrolled use the My VCTs button on the homepage to launch the course when it is time to start. Since V-ILTs use the VCT system, accommodations for technicians who need them are very similar to those offered by VCT courses. The Technician Guide can be found on the course details page on the Center of Learning, which will contain a transcript of any videos that are played during the course. One of the major differences between V-ILTs and VCTs is that V-ILTs are much more intimate and interactive. Live discussion is required as a portion of the course, so if accommodations are needed for these segments, reach out to the Help Desk within a timely manner before the class session so they can be made.
The V-ILT instructor will provide the self-study for the course series and the posttest will be on the Center of Learning with a course number that ends in “P”. Finally, once that is completed, enroll in the P-ILT. P-ILTs are in-person sessions that have accommodations identical to Hands-On ILTs. Technician Guides will be provided to those that attend and if needed interpreters/translators can attend as well, as long as they were the correct PPE. Be sure to reach out to the Training Center admin so proper accommodations can be made.

The P-ILT course numbers end in “H”. Once the three components are completed you will receive your hands-on credit.

Video Resource Library

The videos in the Video Resource Library are short, informative, and are meant to supplement technicians’ technical and non-technical knowledge.

Simply click on the Video Resource Library box located on the Center of Learning home page for access to over 100 branded videos in categories ranging from Auto Body and Paint to Brakes, from Electrical/Electronics to Tools and Equipment.

These brief instructional videos, each from one to nine minutes long, are quick and convenient to view and drive you deeper into topics of instructional interest and value. A representative list of videos include:
Manually Accessing Center Console
Understanding and Measuring Amperage
Driver’s Side Airbag Removal

Video Resource Library videos are not part of any job role Learning Path, there are no tests to take, and no transcripts. They can also be accessed via mobile devices using the Android and iPhone platforms.

Understanding Course Component Flow & Function

GM STC blended training delivers courses in multiple components; these different components provide the service technician with the skills necessary to “Fix it Right the First Time!”

Multiple component courses may use combinations of the following media:
Web-based training addresses the knowledge portion of the class. The material is designed to teach the service technician theory of operation and function of the systems and components, and to introduce diagnostic procedures.

VCT reinforces the knowledge provided in the WBT and introduces the service technician to diagnostic skills necessary to repair the vehicle.

Hands-On allows the service technician to practice diagnostic skills in a setting similar to the work environment.

Virtual and Performance ILT series allow technicians to complete part of the Hands-On course within their dealership using the VCT system. This small group, interactive session is followed by in-dealership Self-Study that the technician completes along with a Center of Learning assessment. Finally, the technician attends a Performance Instructor-Led Training at a GM Training Center where diagnostic procedures are focused on. This series is a new way technicians can complete their Hands-On requirements, reducing the amount of the time they are out of the dealership.

Diagnostic Exercises facilitate the practice of skills, educate, and update knowledge.
Video On Demand has an easy-to-use “Search Videos” function, which allows users to review specific content. This search capability allows technicians to locate a specific topic at any time.

In each component of the blended training, successful completion of a final test is required for course component credit.

Videos augment the basic course components and should be taken at the appropriate time in the Learning Path based on prerequisites.

Credit for Course Components (known as Cross Credits)

The Center of Learning enables technicians who have successfully completed a previous version of a course to conveniently get credit for a new version of the same course in their training history without having to repeat the entire course again.

Here is how it works: Technicians who have completed a current version of a course can access the new version and take just the module(s) with new content. Once complete, the technician will get credit for the new course and will then be able to review all of the modules as a refresher, if needed.

Note: This applies to select courses on an as-needed basis.


Most courses allow for two test attempts. Technicians should review the materials carefully before taking the test; if the test attempts are exceeded, technicians will be locked out indefinitely until GM STC resets the tests on a periodic basis. Unless otherwise noted under respective course components, testing for the listed course components is as follows:

Video On Demand: Testing for content on VOD is available by going to the Course Details page in www.centerlearning.com. When the course is live and ready for viewing, service technicians should click “Launch”. When they are done viewing the course, they must click on the “Take Test” link that appears in the Video On-Demand player at the completion of the video.

Web-Based Placement Assessment

The Placement Assessment process is provided by GM as a means for experienced technicians entering a GM dealership for the first time to quickly receive course credit for their knowledge, skills, and experience. Placement Assessments measure knowledge and/or skills in a given certification area and are designed to allow experienced service technicians the opportunity to test out of course components. They will not be reset if test attempts are exceeded; technicians will need to take the course to receive credit.

Successful completion of a Placement Assessment gives service technicians credit for the web-based and VCT course components and also allows them an opportunity to place out of the component (where applicable). Tests are aligned to a single component.

To take a Web-Based Placement Assessment:

  1. Log onto www.centerlearning.com.
  2. Select the Learning Path, find the course you wish to take the Placement Assessment for, and select its name to get to the “View Course” page.
  3. On this page select the “Test Out” link.

Service Area Placement Assessments (SAPAs)

Intended for those who are new to a GM dealership and also have ASE accreditation, technicians can now take service area placement assessments to earn credit for multiple GM STC courses at once.

These service area placement assessments contain questions pertaining to multiple courses within a service area and will provide credit for each of those courses based on how the technician scores. In order to take a service area placement assessment, the technician must have the corresponding ASE certification. After completing the service area placement assessment, the system will provide the technician with their results, indicating which courses they will receive credit for and which ones they didn’t pass. Same as with the individual placement assessments, technicians only have two attempts at each service area placement assessment.

To find service area placement assessments, navigate to the Center of Learning Catalog and search for “SAPA” or the course number if you know it. You can also select the Testing tab on the main menu, and then select Service Technical, and then Service Area Placement Assessment.

Important Notes:

  • A new Job Aid is available to help dealers determine what placement assessments a technician would need to complete in order to unlock the hands-on checklist and for the service manager to provide hands-on course completion manually. To find this Job Aid, log into the Center of Learning website (www.centerlearning.com) and select the Help/Support button.
  • Placement Assessments are timed. The allotted time is shown at the beginning of each assessment. If a service technician exits a test, the timer will stop and the current question will be closed and will not be repeated, so it’s important to finish a question before exiting. When the service technician is ready, he/she can continue the assessment with the next question.
  • Service technicians have up to two weeks to complete a given Placement Assessment; however, it is recommended that the assessments be completed in one session. Generally, assessments take less than one hour to complete.
  • Placement Assessments and the Paint Placement Assessments can be taken twice.
  • If the service technician fails (e.g., receives a score less than 80%), the technician will not receive credit for the Placement Assessment. However, if the technician receives a score of 80% or above, the technician will receive Placement Assessment credit along with credit for the component associated with the Placement Assessment passed. If the technician does not pass the Placement Assessment, the technician is responsible for completing the associated component to receive credit.
  • Upon successful completion of a Placement Assessment, the service technician’s learning path, training record, and the dealership’s STS report are updated to reflect credit for the corresponding course components.

The Performance Checklist

If a technician receives a score of 80% or greater on a series of Placement Assessments that culminate in a Hands-On course component, a link to the Hands-On Performance Checklist will appear on the test results page. Technicians may download and complete the checklist with their manager.
If both the technician and the manager agree that the technician is able to perform at least 80% of the tasks on the checklist, the manager can grant the technician credit for the Hands-On class through Center of Learning.

In order for the technician to access a performance checklist, they must have passed all the placement assessments that led up to that particular performance checklist either through individual placement assessments, the service area placement assessment, or a combination of the two. If the technician took any of the courses traditionally (meaning they opted not to test out of one via a placement assessment) they lose access to receiving the performance checklist and will need to attend the Hands-On course in order to receive credit. If the service technician successfully completes all Placement Assessments that have a Hands-On component, a link to the Hands-On Performance Checklist appears at the end of the Assessment. The checklist can then be downloaded simply by clicking the link. (Adobe Acrobat Reader 5.0 or higher is required to download the checklist.)

Each Hands-On Performance Checklist contains various tasks related to the Hands-On component. The service technician must be able to correctly perform at least 80% of the tasks listed on the checklist to receive Hands-On component credit. If the service technician can perform at least 80% of the tasks on the Performance Checklist, they should notify their service manager. The service manager can then assign Hands-On credit in www.centerlearning.com.

The service manager must ensure the service technician can perform at least 80% of the tasks contained within the Checklist. Failure to assess the service technician’s skills accurately may result in his/her not qualifying for GM Master Technician Certification.

Note: If the service technician cannot perform at least 80% of the tasks contained within the Checklist, they should enroll in the Hands-On course component.
  • To assign Hands-On credit for the course, refer to the Placement Assessments and Hands-On Checklist Job Aid in the Help/Support section of the Center of Learning. It walks through the steps necessary to provide credit.
  • The Placement Assessments and Hands-On Checklist Job Aid also provides the placement assessment paths to each of the Hands-On checklists.
  • Only service technicians who take and pass all Placement Assessments with Hands-On components can use Hands-On Performance Checklists to obtain Hands-On course credit.

Below is a list of all the Placement Assessments, the corresponding Service Area Placement Assessments, and the corresponding Performance Checklists.

Assessments & Certifications

GM Master Technician Certification (MTC) Assessment

To attain MTC, the technician must be 100% STS in both Silver and Gold and complete all MTC components. GM MTC Assessment is a performance-based event in which each service technician must demonstrate knowledge and diagnostic skills. During the GM MTC event, each service technician is required to solve real vehicle faults by applying the accumulated learning from all courses in the Certification Area. The GM MTC Assessment Program covers 13 of the 15 service categories (it excludes Fundamentals and Emerging Issues. MTC assessments are administered at training locations across the country.

The GM MTC Assessment contains a comprehension component and a practical evaluation to assess the service technician’s knowledge and diagnostic skills. Each Assessment consists of timed exercises that have been developed based upon the critical elements of the courses across the Certification Area and real-life concerns.

To achieve GM Master Technician Certification, a service technician must successfully pass the GM STC Certification Event and be ASE certified in that area.

GM STC recognizes a one-year certification with an annual renewal on Master Technician Certifications. The MTC program allows service technicians to retain their certification if they are at 100% on their STS training requirements.

Once a service technician successfully completes a MTC assessment, that service technician will remain Master Technician Certified as long as they continue to meet their STS requirements for the area(s) in which they are certified. The service technician must maintain their ASE Certification for that category as well.

The Service Technician Assessment Process is as follows:
Each exercise is designed to assess each service technician’s ability to diagnose and apply skills with a simulated real-life customer concern using cross-divisional vehicles.
To successfully complete a Certification Event, the service technician must obtain a total score of 80% or better across the performance-based exercises. During the assessment, a certifier who has received extensive training in conducting performance-based assessments evaluates the service technician’s skills. A service technician who receives GM MTC status receives the following items:


Certificate of Achievement*


*Only the first certificate will be mailed. Additional Certificates are available for download online.
**Additional GM patches are available for purchase through the Center of Learning Help Desk.

If a service technician does not satisfy all of the assessment requirements, a letter indicating the areas for improvement is provided to the service technician.

The service technician’s Learning Path and the STS/MTC tables define the courses in an area that must be completed before the service technician may enroll for the Certification Event. Service technicians can enroll for a Certification Event in the same manner they would for a course component.

During the enrollment process, the service technician is given the option to download:

  • A Certification Event Performance Task List – which allows the technician to self-assess and verify they have the skills necessary to pass the certification
  • A GM MTC Preparation Guide – which provides additional information about the assessments

Cadillac-Branded Patches

Cadillac franchised Dealers have the opportunity to select Cadillac-branded Master Technician Certification (MTC) and World Class Technician (WCT) patches for their technicians. Cadillac Certified Service, in partnership with the Cadillac Dealer Council, implemented this new, creative solution to help Cadillac Dealers recognize their highest achieving technicians. To further elevate the role of our Cadillac technicians, Cadillac franchised dealers can edit existing and new technician profiles to indicate their dealer’s patch preference.

Note: These Cadillac patches will not match the existing MTC or WCT patches. Cadillac Dealers can order additional patches their technicians’ are qualified for at an extra cost.

The decision to switch to Cadillac-branded patches is a dealer decision, NOT an individual technician decision. To change your preferences from GM-branded to Cadillac-branded patches, first coordinate with your Service Manager to approve that your dealer is making the switch.

For the step-by-step instruction on how to update your patch preference, refer to the Cadillac-branded Patches Job Aid on the Center of Learning through the Help/Support button.

GM Master Technician Certification Preparation Guide

The GM MTC Preparation Guide is a reference tool for service technicians preparing to take a Master Technician Certification Event. It helps service technicians by explaining how to prepare for the assessment, what happens on the assessment day, and what happens following the assessment. It is included as an attachment to every certification catalog entry in the Center of Learning.

GM Master Technician Certification Performance Checklist

The Certification Performance Checklist lists the knowledge, skills, and performance criteria in which the service technician should be proficient prior to a Certification Event. The service technician and the service manager may utilize the Certification Event Performance Checklist to evaluate the service technician’s performance. This checklist determines if the service technician is ready to participate in the Certification Event or should attend the instructor-led course component prior to the assessment. The service technician can also use the checklist to prepare for the assessment.

GM World Class Technician (WCT)

A technician can achieve GM World Class Technician status in the Mechanical area. It’s achieved when a technician successfully completes all related training and the appropriate Master Technician Certifications.
Service technicians can achieve WCT status in the Mechanical area when they successfully achieve eight of nine MTCs with their accompanying ASE Certifications. They have a choice of completing either Engine Performance or Diesel Engine Performance along with seven mechanical-related certifications.

Technicians who receive World Class Technician status receive a gift package that includes the following:

  • Letter of Recognition signed by the Director, Dealer Service, and Warranty Operations
  • WCT statue (new design in 2021)
  • WCT patch
  • WCT toolbox medallion (introduced in 2017, new design in 2021)
  • Downloadable certificate from the Center of Learning

Performance Assurance

The GM STC program has an evaluation system in place to measure the effectiveness of the performance-based curriculum and the delivery media. GM STC evaluates the performance of the training program at four levels:

Participant Satisfaction

As service technicians complete a course component, they may also complete an evaluation form. GM STC uses this feedback to measure the service technicians’ attitude or feelings toward the following:
Relevance and value of the component
• Course design
• Effectiveness of the delivery method
• Overall instructor skills, where applicable
The Performance Assurance group compiles and reviews this information. It is then provided on a monthly basis to the Curriculum team, GM STC instructors, and internal Subject Matter Experts (SME) to continuously update and improve the courseware.

Participant Learning

When service technicians complete a course component, a post test is provided to measure their knowledge and skills. This type of evaluation tracks the service technician’s progress through the training program.

Post tests vary based on the delivery method. The WBT, Virtual Classroom Training (VCT), and VOD post tests consist of various types of questions. The Hands-On course component and diagnostic exercise requires service technicians to demonstrate both skills and knowledge.

Participant Transfer of Skills to the Job

The best measurement of the overall training program’s effectiveness is an evaluation of whether the service technician has transferred what was learned and demonstrated in class to the dealership. A select number of technicians are contacted approximately two months after completing the training. This allows the Performance Assurance team to validate that the course skills transfer to the job and add value.

Performance data is investigated to review relationships between training and skills transfer. These investigations examine warranty data and first-time repair information; they involve ongoing and recurring data acquisition and analysis and are integrated into the overall program evaluation process.

Business Impact Due to Skills Transfer

The impact of training on business is under active investigation. Critical areas, such as customer satisfaction and call center activity, are analyzed to determine how training is contributing to performance improvement in these areas.

Other Feedback Mechanisms

GM’s Customer Care and Aftersales division provides Dealer Satisfaction Survey results to GM STC to gauge service managers’ opinions of GM STC training products. The survey results provide valuable input for short-term and long-term improvement initiatives, ensuring continuous improvement to the GM STC program.

ASE Accreditation

Becoming an ASE Accredited Training Provider is a highly regarded accomplishment in the service technical training area, as it recognizes those organizations who provide outstanding technical training to service technicians. GM STC initially achieved this status in the automotive training industry by being awarded accreditation for its Service Technical Training curriculum in 2001.
Becoming accredited is a voluntary ASE certification program for training entities that provide continuing education to working automotive service technicians. The ASE Education Foundation administers the program and the National Institute for Automotive Service Excellence (ASE) grants the certification.

The accreditation program certifies training providers for working service technicians. ASE Education Foundation evaluates the training providers’ process of developing and delivering training and then recommends accreditation, when appropriate, as an ASE Certified Training Provider.

There are many benefits to receiving training from a ASE Certified Training Provider including:

  • The recognition that the training provider and its processes have been reviewed against industry established and endorsed standards.
  • The accreditation process serves as a tool for program improvement.

Dual Nature of the Curriculum

GM STC curriculum is designed to meet two requirements:

  1. Train service technicians to service dealer-specific products
  2. Certify GM service technicians to a common standard

This dual nature of the GM STC curriculum is represented on the within the training categories defined in each training path: Bronze, Silver, Gold, and Master Technician Certification (MTC).
Any course in the GM STC program is available to an active GM service technician provided prerequisites have been met.

The Fundamentals Learning Path contains all the Bronze level requirements, and every technician must complete them in order to achieve 100% STS. The Silver, Gold, and MTC level requirements are found within the other Learning Paths. All Silver level requirements can be completed in dealership. Gold level requirements have an in-person component which must be completed at a training center. MTC level requirements include the ASE Certification and the Master Technician Certification Assessment for that Learning Path.

On the STS Report (available to dealer service managers), empty cells to the right of the service technician’s name in a Certification Area indicate that the course is required for the dealership. In many cases, the STS and MTC requirements are the same. Please refer to the STS Report, Learning Path, and the Technician Training Gap Report for a complete list of training needs. When a service technician successfully completes a course that is listed on both the Learning Path and the STS Report, credit is given for both.

Learning Paths for GM Master Technician Certification

Every GM service technician can choose a Learning Path that includes the requirements for the GM MTC. This Learning Path assists the service technician in identifying the courses to take for a specific Certification Area. A service technician’s Learning Path will carry over from year to year; however, it should be checked at the beginning of each year for changed requirements.

Identifying Courses and Components on the Learning Path

It is important to note on the Learning Path that a course may consist of two, three, or four component delivery media. For example, the GM Global Electrical Systems course (18044.22) is actually delivered as four different components, using different media: Web-Based Training (W1 and W2), and Virtual Classroom Training (D1 and D2). This is shown on the Learning Path as four separate numbers, each with the same 7-digit core course number and a suffix letter/number to denote the delivery medium and, if appropriate, the release number.

Dealer Divisional Service Training Standards (STS)

In response to dealer feedback, we changed how the dealer size is calculated and the impact on Service Training Standards (STS) for all dealers. GM STC worked with the Dealer Fixed Operations Advisory Board (DFOAB) to develop a methodology that aligns service training with overall technical training goals to deliver a truly exceptional service experience for our customers.

Individual dealer STS requirements are determined by a dealer’s Repair Order (RO) count rather than VINs sold. The RO data includes both warranty and customer pay. This data excludes claims that would normally happen before the sale (for example, Pre Delivery Inspection and transportation claims) and stand-alone internal ROs.

The benefits of this change include:

  • STS training requirements align with the service work conducted in the dealership.
  • Dealers will know three months before the end of the year what their dealer size and STS requirements will be the following year.
  • Due to differences between VINs sold and ROs, dealer sizes may change to a different group. Therefore, a dealer’s new size will determine the STS requirements for the following year.

A business rule prevents dealers from changing more than one size per year.

Additional Information

  • A change in groups cannot exceed more than one group per year.
  • Example: In 2023, Hometown Chevrolet was part of Group A. For 2024, Hometown Chevrolet should move into Group C based on their 2023 RO count. However, because of the one-step business rule, this dealership is placed into Group B for 2024.
  • The dealer groups based on RO count will only be used for STS requirements.
  • If RO count is not available, the dealer’s STS requirements will default to VINs sold until sufficient RO count data is obtained.
  • If dealers have a concern with their grouping, they should share these concerns with their District Service Manager (DVM).

Time Line for Dealer Changes

September, current yearDealer notified of pending changes via GlobalConnect message.
October, current yearDistrict Service Manager (DVM) notifies dealers if their group will change for STS requirements.
January, new yearSTS requirements based on Repair Order (RO) count become effective.

Reserve a Seat

Service technicians are required to complete each prerequisite prior to enrolling in VCT or V/P-ILTs. We’ve introduced the Reserve a Seat functionality for technical training in the Center of Learning. This function allows the proactive scheduling of training prior to completing prerequisites.

Benefits of this function include:

  • Session selections based on preferred training center, desired completion date, and participant’s schedule
  • A single click reserves a seat for your desired course as well as all associated prerequisites
  • Visibility of all scheduled sessions and corresponding prerequisites
  • You will receive email reminders identifying pending prerequisites

Service Training Planner

The Service Training Planner builds on the Path to 100% STS button and gives Service Managers unprecedented ability to customize how they manage service training by helping them create a training plan for the year. For instance, Service Managers can train just for STS requirements or for Depth in one or more areas. They can even identify the specific technician to be trained for STS and Depth for each service area. And to help keep the training plan on track, the Center of Learning website auto generates reminder emails once per week until the Service Training Planner is complete.

Service Manager Capabilities and Benefits

  • Proactively create an annual customized training plan for your dealership
  • Set STS goals, by service area, for your dealership technicians
  • Identify which technicians you’d like trained for STS and which you’d like trained for Depth
  • Easily identify which technician needs what training to help your dealer reach its STS goals
  • Identify which technicians are your candidates for Master Technician Certification (MTC)

ASE Certification Information

GM STC requires all new service technicians to provide ASE with their Person ID to allow certification status from the ASE website (www.ase.com) to transfer into GM’s training website (www.centerlearning.com).

Follow directions below to verify that you’ve allowed your status to be released to GM.
To create an ASE profile, click on the “Create myASE Account” link on the page after selecting myASE in the upper right corner of the ASE portal home page (www.ase.com); provide ASE with your Person ID (not 9-digit GMIN).

The Learner ID is displayed and found on your personal Profile page:

To allow your “Certified” status to be released to GM, you must:

  1. Log on to www.ASE.com and your myASE account.
  2. Check the box for “Release my ASE status to others” found by selecting your name in the upper left-hand corner and selecting User Profile. Select the Profile tab, select the Edit Profile button and check the “Release my ASE status to others” box, and select Save.
  3. Select the Company Assigned IDs tab.
  4. Select the +Add Company-Assigned ID button. Select OEM – GM from the Company Name dropdown and enter your Person ID (found in your Center of Learning Profile page) into the ID field.
  5. Select Save.

This process enables ASE to properly identify the service technician as GM affiliated and supply the appropriate ASE certification information to GM STC. Once this change is made, allow 1-2 weeks for your ASE certification status to be visible within the Center of Learning training website. If up-to-date ASE certification records are not showing in www.centerlearning.com four weeks after the most recent testing, the service technician should contact ASE at www.ase.com and update ASE’s records with their Person ID. Contact ASE Customer Service at (800) 390-6789 between 8 a.m. and 5 p.m. Eastern time, Monday through Friday, with questions.

Please note that ASE certified technicians receive a 7-month grace period from when their certification expires to when the expiration is reflected in the Center of Learning. Additionally, located on each of the ASE Certification pages on the Center of Learning, technicians can download an ASE Prep Guide help them prepare them for their needed ASE Certifications. For further information on ASE visit www.ase.com/gm.

View Available Dealer Reports

Service Managers can view changes to STS requirements for 2024 and many other useful Dealer Reports. Select Reports from the home page of www.centerlearning.com and choose from:

  • Dealer Reports
  • Wholesale Reports
  • Enrollment Reports

Predictive STS

As an update to the Dealer STS Report, GM STC has introduced Predictive STS. Predictive STS allows Service Managers to use a drop down menu to select the last day of the current month, or a future month and see what their predicted STS percentages will be at those times. This prediction is calculated based on technicians’ current enrollments in Hands-On or VCT courses, and whether technicians have started VOD or WBT courses. The patterns that appear show current STS (green, forward slash pattern), predicted STS (blue, back slash pattern), and remaining percentage (gray, polka dot pattern). These three different patterns will always add up to 100%. Any categories that are trained for depth will show a percentage of over 100%.

A more detailed view can be explored by selecting the individual Learning Path. Once the Learning Path is selected, the view changes to show individual technicians assigned to that specific path, shows the courses they’ve completed and now includes an additional column that shows their Projected percentage for that Learning Path.

Non-STS Curriculum

GM Service Technical Automotive Readiness Training (GM START)

GM START offers dealers the opportunity to build upon their technician base, build their business, and enhance their customer satisfaction with more experienced and trained personnel. The GM START program helps aspiring technicians perform basic service repairs and maintenance on customer vehicles. GM START features over 90 technical and non-technical self-paced courses with testing and scoring features that provide tangible results.

To find GM START courses in the Center of Learning just type “GM START” into the search bar in the Catalog. The courses have been tagged to appear when searched for using that keyword.
GM START courses do not provide STS credit.

Maintenance Inspection Technician (MIT)

To support dealerships that want to develop their own technicians, GM STC offers a learning path for the Maintenance Inspection Technician (MIT).

The MIT curriculum consists of 27.75 training hours: 19.75 of WBT + 8 hours of Hands-On. There is a Hands-On checklist for the 8 hours of the ILT. Upon successful completion of the MIT curriculum, a technician will be familiar with safety and tools, be able to perform basic maintenance, and be able to conduct a Multi-Point Vehicle Inspection (MPVI).

This job role has no impact on STS.

Boot Camps

Boot Camps are another means for supporting dealerships looking to develop their own technicians. Boot Camp curriculum is designed for the aspiring technician apprentice who may have vocational auto shop experience but has not pursued post-secondary education in automotive technology. Technicians who want to sharpen a specific skill set through instructor-led training will also benefit from Boot Camps.
A Boot Camp is an immersive Hands-On training experience that accelerates the learner’s progression toward completing GM’s performance-based curriculum and maximizes dealership return on training investment.

Dealer Divisional STS and MTC Requirements

STS Requirements

STS requirements for each of the service categories and Medium Duty are listed on the following pages.
Each service category section indicates the course requirements for 2024 Dealer Divisional STS as indicated by the courses that appear under the Bronze, Silver, and Gold categories. The courses required to reach GM MTC in that service area include all of the courses in Bronze, Silver, and Gold and the courses under the MTC category. Required courses are needed to meet the Dealer Divisional STS and for certification. Supplemental courses provide additional content to enhance the curriculum and improve the service technician’s performance but are not part of the Dealer Divisional STS requirements or certification.

Dealer Divisional Service Training Standards

Service technicians who successfully complete all of the STS requirements within each category for a Division will earn Divisional Certification (Buick, GMC, etc.) for that Division.

GM Master Technician Certification

GM MTC, like ASE Certification, is common across all Divisions. Service technicians who successfully complete all GM MTC requirements within each category will earn GM MTC across all Divisions for that category. Since this certification is common, some courses required for GM MTC may not be found as part of the STS. Similarly, some courses required for the STS will not be part of the requirements for GM MTC.

Paint and Refinish

The GM Paint and Refinish Training Process

GM and our paint suppliers have developed a strong training relationship since joining forces. Our relationship enables us to implement the strict procedures necessary to consistently restore a vehicle’s appearance to pre-accident or showroom condition after a paint repair. Our process ensures that painters are knowledgeable and skilled, and we work together to establish performance testing standards to ensure competency certification. Paint suppliers train the technicians while GM monitors adherence to the curriculum and performance standards.

Our process offers several benefits to learners:

  • An expedited method for meeting GM Service Training Standards (STS) and achieving certification
  • An easy way to evaluate a painter’s knowledge level
  • Consistency in skills evaluation among peers

The graphic below depicts our Paint and Refinish Training Process. A painter who successfully completes this process will earn credit for GM Certified Paint/Refinish course number 22041.00 on their training record and dealership’s STS Report. Please allow up to four weeks for the credit to appear in the Center of Learning.

*Basic Paint Assessment 22042.00A plus the appropriate Product-Specific Paint Assessment 22044.


A technician must accomplish at least one of the following:

  • Paint ASE Certification
  • Completion of previous GM or paint supplier training courses
  • One year documented automotive paint experience

Online Evaluation

Once a technician pre-qualifies, he/she must complete the online evaluation by logging on to www.centerlearning.com. Trainees who do not have a log on ID and password may obtain one either by contacting their GM service manager or by calling the GM Center of Learning Help Desk at (888) 748-2687; press 2 then 8. Technicians can locate the online evaluation by clicking Testing > Service Technical > Paint Placement Assessment. The evaluation includes two tests:

Test 1

Test 1

Basic Training – technicians must pass Test 1 before taking Test 2

Test 2

Test 2

OE (Original Equipment) Training – this test is paint manufacturer specific
Section A: OE Product test (primarily performance based product training)
Section B: OE Color test (primarily performance based color tinting/matching) Trainees are given two attempts to pass the two online evaluation tests.

Evaluation Scored

Upon completing an online evaluation test at www.centerlearning.com, trainees receive immediate feedback on how they scored. A score of 80% or higher is required to pass Test 1 and sections A and B of Test 2. This information is sent to the paint supplier Central Training Office (CTO).

If a trainee receives a score of 79% or less on any part of the online evaluation (e.g., Test 1 or either section of Test 2), the trainee should contact their paint supplier representative to enroll in the applicable OE Training course(s). For example, if a trainee scores 80% on the Basic Training test and 80% on the OE Product test section and 79% on the OE Color test section, the trainee should enroll in OE Color test.

Attend OE Course(s)

Note: This step is required only if a trainee does not pass the online evaluation tests.

Upon completing an online evaluation test, the trainee receives immediate feedback from www.centerlearning.com, including a note on which course(s) they need to enroll in.

See the GM Paint Manufacturer Course and Contact Information section of the catalog (Section 2) for course names based on supplier used.

  • Course Contents: Part 1 is primarily performance based product training; Part 2 is primarily performance based color tinting/matching.

For more information pertaining to specific OE courses, call the paint supplier at the number listed in the catalog.

Schedule In-Shop Evaluation

Note: This step is required only if a trainee passes the online evaluation.

Upon successful completion of both online evaluation tests, the trainee should contact either his/her local paint supplier representative or the paint supplier CTO to schedule an in-shop evaluation.

Test 1

Test 1

Basic Training – technicians must pass Test 1 before taking Test 2

Test 2

Test 2

OE (Original Equipment) Training – this test is paint manufacturer specific
Section A: OE Product test (primarily performance based product training)
Section B: OE Color test (primarily performance based color tinting/matching) Trainees are given two attempts to pass the two online evaluation tests.

In-Shop Evaluation

Note: This step is required only if a trainee passes the online evaluation.

A paint supplier representative performs an in-shop evaluation.

Note: If a technician fails the in-shop evaluation, the recommended action is to complete the OE course.

Step #1: OE Approved paint systems information review

Step #1: OE Approved paint systems information review

The representative familiarizes the technician with the OE approved paint systems, product, and process information. It is appropriate for the representative to coach the technician on information and interpretation. It is not appropriate to supply answers for the Observed Performance Evaluations.

Step #2: Observed Performance Evaluations

Step #2: Observed Performance Evaluations

  • The paint supplier representative fills out all of the requested information on the Observed Performance Evaluation sheets (one set for product application and another set for color tinting).
  • The representative observes as the technician demonstrates his/her ability to perform all of the evaluation criteria listed.
  • To pass the course, a technician must achieve a perfect performance score of 100% on both the product application and color tinting evaluations.

Results Sent to Training Administrator

The paint supplier representative sends the completed Observed Performance Evaluation sheets to their training administrator.

Results Sent to Center of Learning

The paint supplier CTO compiles a list of certified painters and forwards it to GM STC.

GM STC Posts Records to Center of Learning Website

GM STC imports the list of certified painters into www.centerlearning.com. Credit shows in training records immediately and on the STS Report within one week.

OE Certification Timing

Trainees must complete the Paint and Refinish training process within a six-month period once they begin.

GM STC Portal Site (www.gmstc.com)

The GM STC portal site provides an overview of the GM STC program. Here, users can find information on the curriculum, training locations, and other details that impact service technical training. This site also provides information about other related programs, as well as the latest news and information regarding GM STC. Please visit this publicly accessible site at www.gmstc.com for more information.

First Responder Guides, Rescue Sheets, and Quick Reference Sheets

As an auto industry technology leader, the GM vehicles being developed and driven on our roads necessitate information sharing with the first responder community: firefighters, police officers, and Emergency Medical Technicians (EMTs). Technology affects vehicle components such as supplemental restraints and the materials used to build vehicles.

While some systems and components are common to traditional GM vehicles, there are now Hybrid/Electric Vehicles systems and components that differ and may affect how a rescue procedure is performed.

GM STC develops First Responder Guides (FRG), Rescue Sheets (RS), and Quick Reference Sheets (QRS) for the new technology vehicles and posts them to www.gmstc.com.
An FRG offers information on vehicle systems and components; both RS and QRS provide the “on-scene” information that first responders need. All of these items feature high quality graphics to support the information.

The FRG provides an overview on how the advance technology vehicle operates and how to identify the vehicle from conventional vehicles, in addition to identifying key hybrid components and how to safely disable the high voltage system. The “No Cut Zones” are provided to ensure the occupant and First Responder are safe during extrication procedures. RS and QRS provide vehicle identification, hybrid components and how to disable the electrical/fuel cell systems.

GM STC provides FRG, RS, and QRS free of charge to First Responders. All can be displayed as long as they are represented as GM information and are not modified in any way.

Note: Guides can be downloaded from www.gmstc.com > First Responders in PDF format onto desktops and mobile devices or printed and saved in vehicles. They can also be accessed using a QR code reader on a smart device (see photo)..

Center of Learning Website (www.centerlearning.com)

The Center of Learning website was implemented to respond to the GM Dealer Council’s requests that dealers have greater ownership of dealership employee training. This website enables dealers to track and organize their dealership employee training and to stay current on their training requirements and needs. It enables users to access a variety of training information at their convenience, providing details on items such as course descriptions, schedules, enrollments, training histories, resource management, and reporting.

To receive New Course email notifications, set “Send New Course Announcements” to Yes on your Profile Page.

Blended Learning

Through its blended media approach (e.g., VCT, VOD, WBT, and V/P-ILT) along with highly qualified instructional design, GM STC helps to extend the service technician’s knowledge. The program also reduces the time that service technicians spend away from dealerships.

Virtual Classroom Training (VCT)

VCT courses bring classroom training directly to your computer. This delivery method improves instructor and participant interaction through a rich media interface and provides an enhanced learning experience for the technician.

Technicians select their desired course and hit Enroll.

Technicians can see a schedule of their course enrollments by viewing “My Enrollments” or “My VCT” on the home page.

Note: To find the Technician Guide (TG), formally called Participant Guides, for VCT you are enrolled in to go to the View Course page by selecting the course’s name. Find the TG on this page and download it before the start of your course per below.

Virtual Instructor-Led Training

V-ILT courses bring part of the hands-on training experience into your dealership. They are the first part in series of course components that once completed provide credit for hands-on training requirements that would traditionally require multiple days in the training center. To enroll, technicians follow the same procedure as VCTs. Find the desired course on the Center of Learning, and select Enroll.

Just like with VCTs, technicians can see a schedule of their course enrollments by viewing “My Enrollments” or “My VCTs” on the home page.

The Technician Guides for V-ILTs are also found the same ways as VCTs. Go to the View Course page for whatever course you wish to view the Participant Guide for and download it using the link found on that page.

Video On Demand

Many prerecorded STC courses are available through Video On Demand (VOD). Emerging Issues courses are released directly to VOD on the second Thursday of each month. Through the combined use of text, 2D and 3D animation, photos, and video, technicians are able to review these training modules on-demand any time of day or night, reducing time away from the service bay. VOD post tests are available directly from the VOD page upon completion of the course.

Web Based Training (WBT)

WBT is knowledge-based training delivered over the internet. Service technicians can access WBT at their convenience. To launch a WBT course component, technicians identify the course using the Catalog Search, Learning Path, or Path to 100% STS link and select Launch.

Center of Learning Reports

Various reports are accessible through the Center of Learning website. These reports help dealership managers determine their employees’ training needs and accomplishments.

  • Dealer Certification Progress Report: shows the breakdown of certification course completion by dealership, job title, and employee
  • Service Training Standards (STS) Report: GM STS shows percentage completion weekly by dealership
  • (GM MD) Service Training Standards (STS) Report: GM Medium Duty Truck (GM MD) STS shows percentage complete weekly by dealership
  • Course Completion Report: course completion summary and detail information
  • Dealer Enrollment Summary (User & Course)
  • Dealer Training Summary
  • World Class Tech – Summary By Region

Master Technician Certification (MTC) Recommendations

The Center of Learning website recommends the next two full courses a service technician needs to complete to achieve MTC in a selected work area. A full course consists of all course components (WBT, online instructor-led, Hands-On). The system provides the additional recommendations to allow for long-term planning of training. For example, a service technician can complete the online instructor-led components of the next two courses and then enroll for the Hands-On course component as soon as prerequisites are satisfied.

Note: The system recommends MTC courses only for service technicians who have selected a Learning Path.

Service Training Standards (STS)

To start, the dealer service manager registers the dealer technicians into specific Learning Paths with the Center of Learning. These Learning paths have percentages that correspond to STS requirements and display their percentage of completion on the homepage. Once a technician is registered to a Learning Path, the Center of Learning website recommends the next two full courses a service technician needs to complete to achieve the dealership’s division-required training in each work area. A full course consists of all components of a course (WBT, online instructor-led, Hands-On). The system provides the additional recommendations to allow for long-term planning of training. For example, a service technician can complete the online instructor-led components of the next two courses, and then enroll for the Hands-On component as soon as prerequisites are satisfied. To meet STS, the system recommends the “best case” service technician, the one closest to fulfilling the training requirements in each work area. As soon as the dealership is 100% in a given work area, the system does not recommend additional training for that area, even though others may need additional training.

Note: The system recommends training only for employees who have specified a Learning Path.

GM Training Tips

Learning Path

The Learning Path is an online feature developed to help dealership managers and employees plan their training. The Learning Path outlines training plans, recommends courses, and summarizes training activity to promote achieving dealership training standards and obtaining individual certifications.
Service managers have the ability to quickly and easily build the Learning Paths for all of the service technicians at the dealership by selecting the following path: Profile > Profile Manager. When service managers click on this link, they get a list of all technicians at their dealer. From there, they can select View Learning Path > Add/Remove Learning Path to get to the page where they can add/remove learning paths for the Service Technical Certification Areas.

ILT Waitlist & Unscheduled ILT Course Request a Class Capability

If you want to enroll in a Hands-On class that is currently full, you can enroll in the waitlist for that specific class. If the opportunity arises that a seat is opened at your preferred training center, you will be enrolled in the open seat, as long as you are next on the waitlist. If there are openings for a class you want to take, but none of the times or locations work for you, you can utilize the Request Unscheduled Course function. By selecting the Request Unscheduled Course link, you can specify what course and where you want the potential offering to take place. These submissions are taken into account when the class organizers get ready to schedule a new offering.

Note: Certain ILT courses are only offered at the Regional Training Centers. Please check your learning path for any restrictions before requesting an unscheduled course.

Online Testing

The Center of Learning website provides users with the ability to take a variety of online tests. These service technical and Sales, Service, and Parts tests include online instructor-led seminar tests and Placement Assessment tests, which allow users to test out of classes. Upon completing the test, users receive immediate feedback on their score. The system immediately updates their training record.

Technician Guides (TGs) for VCTs and V-ILTs

VCT and V-ILT Technician Guides can be downloaded from the Center of Learning website from the View Course page. To download a guide, access the site and find the course, either through your Learning Paths or through the Catalog and select its name. This will bring you to the View Course page where you can download the Technician Guide.

The GM technical training centers have now gone paperless and will provide tablets and tablet friendly TGs for participants to annotate and mark up. Participants can then save their digital TGs to a flash drive and take it with them, with their notes, back to their dealership to reference later.

Training Expiration Email Notification

Before the expiration of a training event (ASE certifications, Certification Events), the Center of Learning website automatically sends an email notification to the employee (provided an email address has been entered into the system). This allows employees to ensure they stay compliant with any and all training requirements.

Search Functionality

The Center of Learning website offers a search functionality. The search engine uses course long names, short names, abstract, notes, and keyboards to try to find a match.

Computer Systems

Computer System Standards/Specifications

For the current recommended and minimum training system requirements for all GM STC training applications, please visit gmdesolutions.com > Home > Techline IT Solutions > Click on “GM IT Standards” to open the .pdf document. This downloadable PDF will help to ensure the proper performance of the GM Center of Learning website and online courseware. As GM dealerships become more dependent on technology to service vehicles, multiple PCs in the service department is a necessity.

Computer System Parameters Affecting Courseware Performance

Generally speaking, three factors affect the performance of the training software on a computer system:

  1. System Configuration: GM has provided the standards with versions for operating systems, applications, and browsers in the “GM IT Standards” document noted above. While applications may run in other environments, or with different configurations, for optimum performance users should ensure they are adhering to these standards.
  2. Memory: The more memory available in the computer, the better the performance.
  3. Open Applications: Open applications slow the courseware performance. It is recommended that all other computer applications be closed when running GM STC courseware.

Online Instructor-Led Training User Requirements

For Participants

Many GM STC courses components are offered via the online system. This live, internet-based training requires no special software. A headset equipped with a microphone must be used in order to participate in the training. This provides live access for “on the spot” question and answer opportunities. Participants must complete the prerequisite courses prior to enrolling in any online instructor-led courses.

It’s easy to set up your computer for this training. In fact, most participants have the basics before they start.

Step 1:

To participate in a session, your computer should meet the following requirements:

  • Windows 7, 8.1, or 10
  • Internet Explorer 8 or higher (IE 9 recommended), Windows Edge, Mozilla Firefox, or Google Chrome
  • Adobe Flash Player 13.0 or higher
  • A hard-wired, high-speed connection (wireless connection is not recommended)
  • Screen resolution of 1024 x 768 (minimum)

Step 2:

Your computer’s built-in microphone and speakers won’t do a quality job. The built-in microphone can pick up the audio output from your speaker. This causes an echo, which will be heard by all participants. Using a PC headset, earphones, or earbuds with attached microphone helps prevent echoing. For best audio quality, a USB-type PC headset with attached microphone is recommended.

GM Automotive Service Educational Program (GM ASEP)

GM has specific technician training initiatives to assist dealers in developing their next generation of technicians. The GM technician training strategy is a three-tiered approach enabling dealers to train technicians at every level — from high school/GM ASE Education Foundation to college/GM ASEP and beyond. For instance, GM ASEP offers training for technically inclined students pursuing a career in servicing and maintaining GM vehicles. The program is a joint effort between GM, its dealers, and select colleges and universities across the United States, Canada, China, and Ecuador. GM ASEP teaches exclusively on current GM products. GM ASEP allows students to alternate between attending college and working at a sponsoring GM dealership for over the course of two years. Upon graduation, students receive an Associate Degree in Automotive Technology (or similar).

GM ASEP incorporates advanced automotive technical training with a strong academic foundation of math, reading, and electronics, and both analytical and technical skills.

Students earn an Associate Degree while working and learning on the job, resulting in a solid education combined with invaluable work experience. Since 1979, GM’s continued commitment to identify and support GM ASEP colleges and universities has produced over 16,000 service technicians.

Any Chevrolet, Buick, GMC, and Cadillac dealer and ACDelco Professional Service Centers (PSC) are eligible to sponsor GM ASEP students.

General Contact Information

GM Service Technician Education Program (GM STEP)

GM STEP is an additional technician training initiative to assist dealers in developing the next generation of technicians. GM STEP provides a way for dealerships to connect to local schools and support youth automotive education programs. Dealers will provide mentoring to help build relationships with students, and encourage them to continue their career path in the automotive field.

The dealer is the conduit to connect a high school or non-ASEP college to GM Service Technical College’s (STC) Learning Management System (LMS), the Center of Learning. Students and instructors will have access to complimentary GM-specific web and video technical training courses through the Center of Learning.

GM STEP also provides graduating students an opportunity to be hired as entry-level Maintenance Inspection Technicians (MITs), Maintenance Light Repair (MLR) technicians, or other roles within the dealer they partnered with.

GM STEP has two different programs, one for high schools and another for colleges. It provides schools with the benefit of a dealer relationship, and complimentary GM-training to offer students. The dealer benefits by fostering a steady pipeline of newly trained technicians through its school partnerships.
For more information go to www.gmstc.com. To get started, dealers should reach out to their zone team representatives.

As a company, General Motors has supported the U.S. military for more than a century, responding swiftly to the need for purpose-built vehicles for use in conflict situations. We’ve employed veterans and military families throughout our history and we continue to be a corporate leader in offering advocacy and significant ongoing financial support for military causes.

In 2013, GM joined forces with the U.S. Chamber of Commerce Foundation’s Hiring Our Heroes program, a national effort to assist veterans, transitioning service members, and military spouses find meaningful employment.

The same year, GM’s Service Technical College began offering free training to veterans and returning service members to prepare them for both technical and non-technical entry-level roles in a dealership. This training can also lead to opportunities with participating ACDelco Warehouse distributors and ACDelco Professional Service Centers.

But that’s not all. GI Bill benefits can be applied to attending GM’s Automotive Service Education Program (ASEP). The GM ASEP training program combines state-of-the-art automotive service, appropriate academic coursework, and real-world internship experiences to give students the best possible preparation for a career as an automotive technician, teaching exclusively on current GM products. The program incorporates advanced automotive technical training with a strong academic foundation of math, reading, and electronics, and both analytical and technical skills. GM ASEP is a joint effort between GM, its dealers, ACDelco Professional Service Center Program Members, and select colleges across the United States, Canada, China, and Ecuador.

GM ASEP students alternate between the classroom and Hands-On work experience at a sponsoring GM dealership. Upon graduation, students earn an Associate Degree in Automotive Technology (or similar), resulting in a solid education combined with invaluable work experience. Any Buick, Cadillac, Chevrolet, GMC, or ACDelco Professional Service Center can sponsor GM ASEP students.

The Hiring Our Heroes initiative has helped more than 200,000 returning military service members and their spouses find training, career counseling, and employment opportunities.

Shifting Gears

The Shifting Gears Automotive Technician Training Program is designed to support service members who will need to transition from military into the civilian workforce. The U.S. Army, GM, and VPS (GM’s training partner) collaborated to design and deliver a training program that provides eligible transitioning Army service members with the necessary skills to become service technicians at GM dealerships.

The program consists of a 12-week customized, on-base technician training curriculum that includes classroom, online, and instructor-led technical training. It launched in August 2014 at Fort Cavazos TX and has graduated over 300 alumni. GM provides the vehicles, VPS developed and delivers the training, and the U.S. Army provides the space and Soldiers. Upon successful course completion and program graduation, students can achieve up to approximately 70% of GM’s STS requirements and Silver Certificates in Electrical, Brakes, Engine Mechanical, Engine Repair, HVAC, and Diesel. Participants also have access to an Engagement Specialist, located at Fort Cavazos to help prepare them for their civilian job search and support the regional GM team in connecting them with hiring dealerships.

Alumni from the Shifting Gears program receive prep training from Central Texas College in Electrical and Brakes ASE test taking, and the registration and test fees are both paid for by the Texas Workforce Commission, provided the alumn has a plan to possibly work in Texas.

A Department of Labor Apprenticeship Program can also be instituted at a GM dealership and used in tandem with the Shifting Gears Program. Shifting Gears alumni will place higher into DOL Apprenticeships, reducing training costs and time. The alumni also are able to receive a living stipend through the VA if they enroll in a DOL approved apprenticeship. The DOL Apprenticeship Program is a great starting point for any entry level technician and is also a great asset to GM dealerships to acquire and retain quality technicians.

When a Shifting Gears alumn is hired, the Center of Learning bills the Dealer Open Account in three installments of $2,200 each:

  1. The first, at Date of Hire.
  2. The second, 90 days later.
  3. The third, 90 days after that.

Should a Shifting Gears alumn separate from the dealership within six month of the Date of Hire (when the hiring Dealer activates the technician in the Center of Learning at www.centerlearning.com), the Dealer is eligible for a refund of paid training fees.
