BACKGROUND
MEDIUM/HEAVY TRUCK TECHNICIAN TRAINING ACCREDITATION PROGRAM
The Board of the National Institute for Automotive Service Excellence (ASE) is responsible for
accreditation of automotive (automobile, collision repair & refinish, medium/heavy truck)
programs at secondary and post-secondary levels. ASE will grant accreditation to programs that
comply with the evaluation procedure, meet established standards, and adhere to the policies in
this document. Program accreditation is under the direct supervision of the Board of Directors
and such personnel designated or employed by the ASE Education Foundation.
History
The ASE standards for automobile program certification were introduced in 1982. Standards for
collision repair & refinish programs were launched in 1989 and truck standards followed in
1992. The ASE Education Foundationās role in the process was to work with industry and
education to update the standards on a regular basis and evaluate programs against those
standards. Based on a positive evaluation, programs are accredited by ASE for a period of five
(5) years.
Effective January 1, 2018, all programs that held current NATEF program accreditation, were
grandfathered as accredited by ASE until such time that they were due to renew their
accreditation.
After a lengthy process that included discussions with industry, employers, and educators, the
ASE Education Foundation conducted a series of workshops and webinars to review the
medium/heavy truck standards. In January 2018, a new model for medium/heavy truck program
standards was published. This new model introduced standards based on three (3) levels rather
than by medium/heavy truck area (brakes, electrical/electronic systems, etc). The three levels
are: Inspection, Maintenance, & Minor Repair (IMMR), Medium/Heavy Truck Service
Technician (TST), and Medium/Heavy Master Truck Service Technician (MTST). Each
successive level includes all the tasks of the previous level in addition to newly designated tasks.
In other words, the TST task list includes all of the IMMR tasks plus additional tasks. The MTST
task list includes all of TST tasks plus additional tasks specifically for MTST.
Programs may begin submitting applications using these materials January 1, 2022.
Applications using the 2018 requirements will no longer be accepted after June 30, 2022.
The cost to each program for accreditation will be as reasonable as possible to encourage
program participation. This cost will include program evaluation materials, application
(processing) fee, and on-site team evaluation materials. The honorarium and expenses of the
Evaluation Team Leader (ETL) are paid directly to the ETL from the program being accredited.

POLICIES
ACCREDITATION PROCESS
Program Evaluation
The accreditation process begins with an extensive program evaluation performed by training
program instructors, administrators, and advisory committee members. Members of this group
compare the program to national standards and have the opportunity to make improvements
before submitting the application and a summary of the evaluation to the ASE Education
Foundation.
Application Review
The application for Initial Accreditation or Renewal of Accreditation is sent to the ASE
Education Foundation, where it is reviewed to determine if the program qualifies for an on-site
team evaluation.
Programs will have a maximum of 12 months to complete the accreditation process from the date
their completed application for Initial or Renewal of Accreditation is received by the ASE
Education Foundation. After 12 months, the program must submit a new application. This 12-
month time frame may be shortened when applying under standards that are in the process of
being phased out.
Renewal of Accreditation
Program accreditation is valid for five (5) years. Programs seeking accreditation renewal should
submit a renewal application at least six months prior to their programās accreditation expiration
date. If the program has not completed the renewal process prior to the programās accreditation
expiration date, the accreditation will expire, and the program will be removed from the ASE
accredited programs list. Programs whose accreditation has expired will have 60 days post
expiration to submit a renewal application under current program requirements. Any program
whose accreditation is expired beyond 60 days must follow the Initial Accreditation application
process.
On-Site Evaluation
If the program qualifies, an Evaluation Team Leader (ETL), an educator (current or retired), of a
an accredited program, trained by the ASE Education Foundation and with current ASE master
certification credentials, is assigned to the program and an on-site visit is conducted.
Recommendation for Accreditation
When the standards are met, ASE program accreditation is valid for five (5) years from the
official accreditation date issued. If a currently accredited program successfully completes the
accreditation renewal process before the expiration date of the current five year accreditation
timeframe, accreditation renewal does not begin until the current expiration date.
Effective 1/1/2022 Page 12 of 125 Revised 3/1/2022
If an accredited program fails to complete the accreditation renewal process before the expiration
date of the current accreditation timeframe, the program accreditation ends until the renewal
process has been successfully completed.
Programs having difficulty in meeting the hours or tools & equipment accreditation requirements
should consider the following options:
A. Borrowing equipment needed for instruction from a manufacturer, dealership, or
independent repair shop.
B. Arranging for instruction on tasks requiring equipment not available in the school
program at a dealership or independent repair shop.
Programs choosing option A or B are required to show documentation on where the tasks are
taught, by whom, and how students are evaluated.
Effective 1/1/2022 Page 13 of 125 Revised 3/1/2022

3. The average rating on each of Standards 6, 7, 8, 9 and 10 must be a four (4) on a
five-point scale. The program will not be approved for an on-site evaluation if the
average is less than four (4) on any of those standards. The program should make
improvements before submitting the application to the ASE Education Foundation for
review. A program will be denied accreditation if the on-site evaluation team
average rating on Standards 6, 7, 8, 9 or 10 is less than four.
4. A āYESā response must be achieved on all six (6) criteria in Standard 12 if the program
is using it to meet the instructional hour requirements for the purpose of accreditation.
The program will not be approved for an on-site evaluation if it cannot support a āYESā
response to each criterion on the program evaluation form. A program will be denied
accreditation if the on-site evaluation team does not give a āYESā response to all six
(6) criteria in Standard 12. This applies only to programs using the provisions in
Standard 12 for the purpose of meeting instructional hour requirements.
5. A program may not be approved for an on-site evaluation if the average rating on
Standards 1- 5 and 11 is less than a four on a five-point scale. A program may be
denied accreditation if the on-site evaluation team average rating on Standards 1 - 5
and 11 is less than four. Approval for on-site evaluation or accreditation will be made
by the ASE Education Foundation, based on the number of standards rated at 4 or 5 as
well as the individual rating on any standard rated less than four.

documented hands-on work as a technician in a retail or fleet medium/heavy truck repair
business outside the school (e.g., part-time work or summer externship) for one (1) hour
of update technical training, up to a maximum of ten (10) hours of update technical
training each year, toward the annual update training requirement. The work must be
related to the areas they teach and take place in the same year for which substitute credit
is sought. The ASE Education Foundation reserves the right to verify all hands-on work
information reported and determine whether it meets all requirements.
8. The program Advisory Committee, consisting of at least five (5) industry members (not
counting school personnel), must conduct at least two working meetings a year. Minutes
of the meetings must be provided to the on-site evaluation team for review and must
reflect relevant areas of the standards as having been considered by the Advisory
Committee.
9. The Program Standards recognize that program content requirements vary by program
type and by regional employment needs. Therefore, flexibility has been built into the task
list by assigning each task a priority number. A program must include in their
curriculum the designated percentage of tasks (or more) in each priority numbered
category (P-1, P-2, and P-3) to be accredited. For IMMR, TST, and MTST
Medium/Heavy Truck programs, the following minimum percentages are required:
At least 95% of all Priority 1 (P-1) tasks must be taught
At least 70% of all Priority 2 (P-2) tasks must be taught
At least 25% of all Priority 3 (P-3) tasks must be taught
Effective 1/1/2022 Page 15 of 125 Revised 3/1/2022
10. A program that does not meet the minimum hour requirements may be eligible for
accreditation if both of the following conditions are met for the level of accreditation
being sought:
a. Show evidence that all graduates from the previous academic year have taken the
professional level ASE certification examination, and
b. Show documentation that 75% of those graduates passed the professional level ASE
certification tests. NOTE: The ASE Entry-Level Certification tests cannot be used to
meet this requirement.
11. The concern for safety is paramount to the learning environment. Each program level has
the following safety requirement preceding all related tasks:
Comply with personal and environmental safety practices associated with clothing;
eye protection; hand tools; power equipment; proper ventilation; and the handling,
storage, and disposal of chemicals/materials in accordance with local, state, and
federal safety and environmental regulations.
Effective 1/1/2022 Page 16 of 125 Revised 3/1/2022
QUALIFICATIONS OF EVALUATION TEAM LEADERS (ETLs)
Evaluation Team Leaders (ETLs) are educators who have been trained by the ASE Education
Foundation to lead the on-site evaluation. The ASE Education Foundation will assign an ETL
once a program has been approved for an on-site evaluation. Every effort will be made to assign
an ETL located close to the school to reduce the cost for the evaluation. Up to three additional
team members, selected by the program and approved by the ETL, are required for a
medium/heavy truck program on-site evaluation. (See the following page for additional
information about team members and on-site teams.)
Persons selected as ETLs must:
1. have a minimum of six years of combined experience as a medium/heavy truck
technician and a current or retired medium/heavy truck instructor (at least three years
experience as a medium/heavy truck technician is required);
2. have a B.A. or B.S. in Education from a college or university recognized for teacher
training by the state; and
3. be a current ASE certified master medium/heavy truck technician (T2-T8).
Or, if a state does not require medium/heavy truck instructors to have a B.A. or B.S. degree, the
following qualifications will apply:
1. six years experience as a medium/heavy truck technician,
2. four years medium/heavy truck teaching experience at the secondary or post-secondary
level, and
3. current ASE certified master medium/heavy truck technician (T2-T8).
ETL candidates who are active instructors must be directly associated with an accredited
program. ETL candidates who are inactive instructors must have formerly been directly
associated with an accredited program.
ETL training is valid for three years. However, an automatic three-year renewal is granted every
time an ETL conducts an on-site evaluation. ETLs are required to attend additional training
sessions or serve as a team member if they have not conducted an on-site evaluation within three
years. This additional training is required even though the individual holds current ASE

QUALIFICATIONS OF ON-SITE EVALUATION TEAM MEMBERS
The program requesting accreditation is responsible for recruiting and recommending on-site
evaluation team members. The ETL must approve individuals recommended by the program.
The on-site evaluation team members must be practicing medium/heavy truck technicians, or
service managers or shop owners with prior experience as service technicians, from businesses in
the area served by the training program.
Evaluation team members must have:
1. a high school diploma or the equivalent, and
2. at least five years full-time experience as a general medium/heavy truck technician.
ASE medium/heavy truck certification is recommended but not required.
In addition to the ETL, the Initial Accreditation evaluation team has three team members. If the
program is manufacturer-specific (e.g., ASEP, ASSET, T-TEN, etc.) it is recommended that the
team members be from dealers associated with that manufacturer. If the program is generic, it is
recommended the team members be from a mixture of dealer and aftermarket repair facilities.
In addition to the ETL, the Renewal of Accreditation evaluation team has two team members. If
the program is manufacturer-specific (e.g., ASEP, ASSET, T-TEN, etc.) it is recommended the
team members be from dealers associated with that manufacturer. If the program is generic, it is
recommended the team members be from a mixture of dealer and aftermarket repair facilities.
Each program requesting accreditation must also identify their choice for an alternate evaluation
team member should one of the other team members be unable to participate on the date(s) of the
evaluation. The alternate team member may be from a dealership, an aftermarket repair facility,
or a current advisory committee member who did not participate in the self-evaluation completed
by the advisory committee as part of the application process. No more than one current advisory
committee member can serve as a team member during the on-site evaluation.
Team members must not be former instructors or graduates of the program within the past three
years or relatives of the administrator or instructor.
Each program must identify their selections on the On-Site Evaluation Team Member List which
is part of the application for Initial or Renewal of Accreditation.
Effective 1/1/2022 Page 18 of 125 Revised 3/1/2022
TASK LIST INFORMATION
An essential element of any curriculum or training program is a valid task list. Medium/Heavy
Truck technician instructors need a well-developed task list that serves as a solid base for course
of study outlines and facilitates communication and articulation of their training programs with
other institutions in the region.
It is a policy that the task list developed by the National Institute for Automotive Service
Excellence (ASE) serves as the basis for the ASE Education Foundation task list. Panels of
technical service experts from the automotive service industry and career technical education are
called upon to develop and validate the task lists.
The ASE Entry-Level Certification tests are based on the ASE Education Foundation task lists.
These tests can provide the student with their first industry-recognized certification through
ASE.
Additional information on the development of the task list can be found in the Task List section.
All tasks have a Priority designation. The Program Standards recognize that program content
requirements vary by program type and regional employment needs. Therefore, flexibility has
been built into the task list by assigning each task a priority number. The priority number simply
indicates the minimum percentage of tasks that a program must include in their curriculum in
order to be accredited.
Effective 1/1/2022 Page 19 of 125 Revised 3/1/2022
TOOLS AND EQUIPMENT INFORMATION
The basic tools and equipment that must be available for use in the medium/heavy truck program
are listed in the Tools and Equipment section. Many tools and much of the equipment are the
same for some or all of the three levels. However, some equipment is specialized and must be
available for use in the selected program level. The specialized tools/equipment lists for IMMR,
TST and MTST are included in the Tools and Equipment section.
The student hand tool list covers all program levels. This list indicates the tools a student will
need to own to be successful.
Although no brand names are listed, the equipment and tools must address the following
programmatic issues:
1. Safety - Equipment and tools must have all shields, guards, and other safety devices in
place, operable, and used.
2. Type and Quality - The tools and equipment used in an accredited program must be of the
type and quality found in industry. They must also be adequate and in sufficient quantity
to meet the program goals and student performance objectives.
3. Consumable Supplies - Supplies should be in sufficient quantity to assure continuous
instruction. Consumable supplies, such as solvents, sand paper, etc. are not listed.
4. Maintenance - A preventive maintenance schedule should be used to minimize equipment
down time.
5. Replacement - A systematic schedule for replacement should be used to maintain up-to-
date tools and equipment at industry and safety standards. Information gained from
student program evaluations as well as advisory committee input should be used in the
replacement process.
6. Inventory - An inventory system should be used to account for tools, equipment, parts,
and supplies.
7. Parts Purchasing - A systematic parts-purchasing system should be used from work order
to supplier.
8. Hand Tools - Each student should be encouraged to purchase a hand tool set during the
period of instruction.
9. Storage - Adequate storage of tools should be provided. Space for storage of the students'
hand tools should be provided.
Effective 1/1/2022 Page 20 of 125 Revised 3/1/2022
GO/NO-GO STANDARDS
The Program Standards for Initial Accreditation and Renewal of Accreditation are identical.
Items listed below are considered Go/No-Go items and are critical for accreditation and are in
bold print in the Medium/Heavy Truck Program Evaluation materials.

Standard 12 ā E-learning). Programs must also meet the hour requirements listed in item 2 of the
Medium/Heavy Truck Minimum Requirements appropriate for the level of accreditation sought.
If the program does not meet these go/no-go requirements, do not apply for accreditation
until it it does.
In addition, an on-site evaluation will not be scheduled unless the average score on each of
Standards 6, 7, 8, 9, and 10 is at least a 4 on the Medium/Heavy Truck Program
Evaluation. Please refer to the Medium/Heavy Truck Program Requirements for more
information.
Instructors must be ASE certified in accordance with the requirements for the program
level being accredited. Please refer to item 6 of the Medium/Heavy Truck Minimum
Requirements.
Effective 1/1/2022 Page 22 of 125 Revised 3/1/2022
RECOGNITION FOR ACCREDITATION
A program approved for Initial Accreditation or Renewal of Accreditation will receive a plaque
that includes the school's name and the expiration date of accreditation. A statement will read:
"THE INSTRUCTION, COURSE OF STUDY, FACILITIES AND EQUIPMENT OF THIS
INSTITUTION HAVE BEEN EVALUATED BY THE ASE EDUCATION FOUNDATION
AND MEET STANDARDS OF QUALITY FOR THE TRAINING OF MEDIUM/HEAVY
TRUCK TECHNICIANS AT THE FOLLOWING LEVEL:
_________________________________
Institutions receiving ASE program accreditation are encouraged to put the following statement
on the graduate's diploma or certificate:
"The person holding this diploma has participated in a medium/heavy truck technician
training program that was accredited by ASE and has completed instruction at the
following level:
_________________________________
A screened ASE Education Foundation logo may be overprinted with the above statement and
placed on the graduate's diploma. A logo is provided in the promotional material a program

Programs granted Initial Accreditation will also receive a 24"x 30" sign indicating that the
training program is ASE accredited.
Effective 1/1/2022 Page 23 of 125 Revised 3/1/2022
INTEGRATED ACADEMIC SKILLS RECOGNITION
A technicianās job description consists of far more than the performance of manipulative tasks
required to service todayās complex vehicles. Successful technicians must possess an array of
workplace skills and a unique blend of academic and technical skills.
To that end, the ASE Education Foundation Board of Directors has approved an updated version
of integrated academic skills in the disciplines of English, mathematics, and science for
automotive technicians. This new document, titled Being Relevant Matters was made possible
through a grant program created by the ACT Foundation. It provides a road map for teachers and
school administrators to balance the needs of technical education with the ever-increasing
academic requirements for high school students who have opted for a career/technical education
over the college prep path.
Teams of automotive and academic teachers, representing the disciplines of English/language
arts, mathematics and science, identified academic principles and subject matter embedded in
various automotive tasks. These were then formatted into content descriptions that include
templates for crafting credit-worthy integrated or stand-alone academic classes.
The ASE Education Foundation will issue a certificate of excellence to those programs that
provide documentation including, but not limited to, student assignments or activities,
classroom/lab instructional materials, student performance records, and interviews with
academic instructors.
Programs that wish to receive recognition must complete the Integrated Academic Skills
Recognition form and return it with the application for Initial Accreditation or Renewal of
Accreditation. Documentation on integrated academic skills activities must be available for the
ETL at the time of the on-site evaluation.
Programs may receive recognition in English, mathematics, science, or any combination of the
three areas.
The Integrated Academic Skills guide Being Relevant Matters is available on the ASE Education
Foundation website at www.ASEeducationfoundation.org.
Effective 1/1/2022 Page 24 of 125 Revised 3/1/2022
APPEALS AND ACTION FOR REVOCATION
APPEALS: PROGRAMS APPLYING FOR ACCREDITATION
A complaint received from any school concerning the procedures, evaluation or accreditation of
the medium/heavy truck technician training program must be made in writing to the ASE
Education Foundation in Leesburg, VA. It will be immediately referred to a Grievance Examiner
who will acknowledge receipt of the complaint in writing to the complainants. Thereafter, a
Grievance Examiner will investigate the complaint and prepare a report. A copy of the report
will be given to the complainants and to an Appeals Committee within thirty (30) days of the
receipt of the complaint.
The Appeals Committee will review the findings and recommendations of the Grievance
Examiner, together with the complaint and any data supplied in connection therewith. The
Appeals Committee will be empowered to dismiss the matter or to initiate such action as it may
deem appropriate.
If the complainants desire to review the Appeals Committee's evaluation, they may do so at the
office of the Grievance Examiner in Leesburg, VA. However, they will not be permitted to make
copies of the results.
ACTION FOR REVOCATION: ASE ACCREDITED PROGRAMS
The Appeals Committee will also advise the ASE Education Foundation President of its
judgments and recommendations for action in any cases of malpractice or misrepresentation
involving the misuse of ASE program accreditation for a medium/heavy truck technician training
program. Upon receipt of a complaint alleging misuse or misrepresentation by an accredited
program, a Grievance Examiner will be notified. The Grievance Examiner will notify the parties
against whom the complaint has been filed, in writing, indicating the alleged wrongdoing. The
parties will be further advised that they may submit a written explanation concerning the
circumstances of the complaint within thirty (30) days. After the Grievance Examiner has
considered the complaint and received the explanation, if any, the Grievance Examiner will
determine whether there is a reasonable basis for a possible wrongdoing. If the Grievance
Examiner finds such a basis, the Grievance Examiner will inform the parties of the findings. At
that time, the Grievance Examiner will inform the parties of their right to a hearing before an
Appeals Committee. The parties will have fifteen (15) days to notify the Grievance Examiner, in
writing, of their decision.
In the event the involved parties elect to be bound by the findings of the Grievance Examiner
without a hearing, the Grievance Examiner will submit a written report with recommendations to
the Chair of the Appeals Committee. This report will be submitted within sixty (60) days of the
receipt of the waiver of a hearing. The Chair of the Appeals Committee will mail a copy of the
Grievance Examiner's findings and recommendations to the parties. In the event that the
involved parties elect to appear at a hearing, the Chair of the Appeals Committee will call a
Board of Inquiry. This Board will consist of four ASE Education Foundation and/or ASE Board
members. The Board of Inquiry will be convened in Leesburg, VA at a date and time determined
Effective 1/1/2022 Page 25 of 125 Revised 3/1/2022
by the Chair. The Board will notify the involved parties, in writing, regarding the time and place
of the hearing.
The Grievance Examiner will be responsible for investigating and presenting all matters
pertinent to the alleged wrongdoing to the Board of Inquiry. The involved parties will be entitled
to be at the hearings with or without counsel. The parties will be given an opportunity to present
such evidence or testimony as they deem appropriate.
The Board of Inquiry will notify the Chair of the Appeals Committee of its findings and
recommendations in writing within ten (10) days after the hearing is completed.
The Appeals Committee will review the findings and recommendations of either the Grievance
Examiner if a hearing was waived, or the Board of Inquiry if a hearing was held. The Appeals
Committee will determine if the record on the complaint supports a finding of conduct contrary
to or in violation of reasonable practices. If two-thirds of the Appeals Committee so find, the
Committee will recommend to the ASE Education Foundation President the appropriate
sanctions or courses of action against the parties charged.

ā¢ Programs whose accreditation has expired will have 60 days post expiration to submit a
renewal application under current program requirements. Any program whose accreditation
is expired beyond 60 days must follow the Initial Accreditation application process.
2. Review of Application
The ASE Education Foundation will review the materials within 30 days. Following the
review, the Program Administrator will be notified about the status of the application. The
program will be identified as one of the following:
a. Qualified for on-site evaluation for the level listed on the application.
b. Not qualified for an on-site evaluation at that time. The ASE Education Foundation
will indicate specific improvements that must be made before the on-site evaluation
can be approved.
3. Evaluation Team Leader (ETL) Assigned, Program Coordinator Makes Contacts
ā¢ The ASE Education Foundation will assign an Evaluation Team Leader (ETL) to the
program.
ā¢ The program administrator and primary contact will be notified of the ETL assignment
and provided with the necessary ETL contact information.
ā¢ Included with the notification of ETL assignment will be an On-site Evaluation
Agreement. The On-site Evaluation Agreement outlines the required documentation to be
provided to the ETL and the costs for the ETL's services and expenses. All costs will be
paid by the institution requesting accreditation. This agreement must be completed and
returned to the ETL and a copy provided to the ASE Education Foundation after the on-
site date has been established.
ā¢ The ETL will contact the Program Coordinator to arrange a date for the on-site
evaluation. It is acceptable for the Program Coordinator to initiate contact with the ETL.
ā¢ With a legitimate reason, the Program Coordinator may contact the ASE Education
Foundation to request a different ETL. A request for a different ETL must be in writing
and specific as to the reason for the request. (The ETL assigned must NOT be a present
or former teacher or administrator, or a member of the Advisory Committee of the
program to be evaluated.)
4. Send On-Site Evaluation Agreement, Copy of the Application, Course of Study, List of
On-Site Evaluation Team Members, Program Graduate Employer Contact Form, and
Necessary Payment Forms to the ETL
A copy of the items listed below must be received by the ETL at least two weeks prior to the
on-site evaluation or the on-site must be rescheduled.

ā¢ Tasks and information to be taught using e-learning materials outside of
classroom/lab/shop time
ā¢ Number of hours allocated to using e-learning instructional materials outside of
classroom/lab/shop time correlated with vendor/developerās average completion time for
each module
ā¢ Sample of the Learning Management System (LMS) used to track student progress
The On-site Evaluation Team Member List must be included for the ETL to review and
approve. Once a date has been set and the on-site evaluation team members have been
approved by the ETL, the program coordinator must contact the on-site evaluation team
members to make arrangements for the evaluation day(s).
A Program Graduate Employer Contact form with the names of 6 previous graduates must be
provided. The program instructor or administrator should contact the employers prior to the
on-site visit informing the employer a representative from ASE Education Foundation will be
in contact with them regarding their experience as a student and graduate.
5. On-Site Evaluation
Initial Accreditation requires 2 consecutive days while students are in class for the on-site
evaluation review of all the standards. However, if more than one program is applying for
accreditation (general automotive and GM ASEP, for example), additional team members
and additional days may be required to complete the on-site evaluation. The ASE Education
Foundation will determine the need for additional team members and days.
Renewal of Accreditation requires a 1-day on-site evaluation while students are in class.
The on-site evaluation team reviews Standards 2.1A, 6-10 (and Standard 12 if applicable) as
well as all go/no-go (critical) items. However, if the Program Self Evaluation average on
Effective 1/1/2022 Page 33 of 125 Revised 3/1/2022
Standards 1-5 or Standard 11 is less than 4, the on-site evaluation team must also review
these standards. The ASE Education Foundation will determine whether an additional day or
additional team members will be required to complete the evaluation.
6. ETL Reports Results
The ETL will submit all on-site evaluation materials and a final report to the ASE Education
Foundation with a recommendation for or against program accreditation.
7. Program Accreditation
The ASE Education Foundation will review the final report and all additional evaluation
materials to determine whether the program meets the requirements for accreditation and will
make their recommendation to the Board of Directors. The President will approve
accreditation as sanctioned by the Board of Directors.
Programs that do not earn accreditation will be given a written report specifying
improvements that must be made to qualify for accreditation.
The Program Administrator will be notified of all decisions regarding the approval status of
all programs applying for accreditation. Any appeals must follow the stated appeals process.
8. Display and Reporting of Accreditation
A wall plaque identifying the accredited level will be forwarded from the ASE Education
Foundation to the program administrator. Schools must accurately report the level of
accreditation.
9. Accredited Technician Training Program List
The ASE Education Foundation maintains a current listing of all ASE accredited programs.
The list is made available on the website at www.ASEeducationfoundation. Programs that do
not complete the renewal process by their expiration date will be removed from the list.
10. Annual Report
Each year all accredited programs are required to update all contact information.
11. Compliance Review
A program is accredited for five years. A compliance report is completed by the program
Advisory Committee after 2Ā½ years. The compliance report is used to verify that a program
is maintaining the program standards. The ASE Education Foundation will notify the
program administrator at the 2-year anniversary of accreditation that a compliance review is
due. The report is due 6 months after the notification date. If the report is not received within
60 days past the due date, the programās status will be set to āDue to Reaccreditā and the
Effective 1/1/2022 Page 34 of 125 Revised 3/1/2022
program will be removed from the roster of accredited programs. The program may be
required to have an on-site visit conducted by an ETL and ASE Education Foundation
Directors, staff, consultants, or other designated representatives to verify program
compliance prior to the program status being restored to āAccredited.ā
Additionally, the ASE Education Foundation may randomly select programs at the 2Ā½-year
period for an on-site compliance review by an ETL and ASE Education Foundation
Directors, staff, consultants, or other designated representatives. Selected programs will be
notified, in advance, of the on-site review. Programs should be prepared to provide
documentation on how they are maintaining the standards. All costs for this on-site review
will be paid by the ASE Education Foundation.
Compliance review forms are available on the website at www.ASEeducationfoundation.org.
12. Renewal of Accreditation
A program is accredited for five years. The ASE Education Foundation will contact the
program twelve (12) months prior to the accreditation expiration date. Programs can
download the accreditation materials at www.ASEeducationfoundation.org and follow the
process outlined above.

*ETLs are to receive an additional honorarium of $100 per additional program when
evaluating multiple programs at one location. Example: An ETL evaluates one general
program and one manufacturer-specific program during an Initial Accreditation on-site
evaluation. The honorarium paid to the ETL would be $500 for the standard two-day honorarium
plus $100 for the additional program, for a total honorarium of $600.
ETLs are paid as independent contractors, not as school employees.
**Mileage is to be reimbursed at the ābusiness purposeā rate specified by the IRS. Please visit
IRS.gov for the current mileage reimbursement rate.
Costs of Initial Accreditation and Renewal of Accreditation are subject to change. Contact the
ASE Education Foundation for current information.

SPECIAL CONSIDERATIONS FOR RENEWAL OF ACCREDITATION
Evaluation
The Renewal of Accreditation process requires a one-day on-site program evaluation while
students are in class. Team members only evaluate Standards 6-10 unless the ETL is given other
instructions by the ASE Education Foundation. The ETL must submit a Final Report Form for
each program evaluated.
Conducting an On-Site Program Evaluation when the Self Evaluation has rated a Standard
Below 4
Renewal of Accreditation requires that four members of the Advisory Committee complete the
Program Evaluation form. If a rating on one or more standards is below a 4 on the 5-point scale,
it will be necessary for the on-site evaluation team to rate those standards in addition to
Standards 6-10. The ASE Education Foundation will advise the ETL if it will be necessary to
rate additional standards. An additional team member or an additional day may be required for
the on-site evaluation. The ASE Education Foundation will make that determination before the
on-site evaluation is scheduled.
Renewal of Accreditation for Two or More Programs
It may be necessary to schedule an additional day or add team members if more than one
program is due to renew their accreditation at the same time (example: general automotive, GM
ASEP, etc.). The ASE Education Foundation will make that determination before the on-site
evaluation is scheduled. The ETL must submit a separate Final Report Form for each program.
Effective 1/1/2022 Page 37 of 125 Revised 3/1/2022
EVALUATION GUIDE
AUTOMOTIVE PROGRAM EVALUATION
Everyone associated with an automotive training program, whether it is automobile, collision
repair & refinish, or medium/heavy truck, should be aware that an extensive program self-
evaluation must be conducted by school personnel and certain criteria must be met to be
approved for an on-site team evaluation. Documentation must be available for the on-site team to
verify that the program meets all requirements for accreditation. The good news is the on-site
team will evaluate exactly the same items the school evaluated.
Both the Program Standards and Program Evaluation form contain helpful hints to assist
programs through the accreditation process. These hints were developed by a group of
experienced ETLs, ASE Education Foundation staff and Directors. The result is a collection of
suggestions for schools and ETLs alike to be used as a guide for preparing, reviewing, and
evaluating the documentation needed for program accreditation. These suggestions are meant as
examples but there are many other documents that can be used to show how programs meet the
standards for accreditation.
When evaluating the statements on the Program Evaluation form read the statement on the form,
refer to the Program Standard for additional information on each standard sub-section. It is
helpful to make notes of reference materials used to rate the standard. While preparing for the
on-site evaluation, make copies of the information, clearly mark the reference, and highlight
specific information for each sub-section. For example, Standard 1.2 A. asks to rate program
materials available (brochure or catalog) on the inclusion of admission requirements,
employment potential, etc. Have a copy of the school catalog available for the team with the
section identified with a sticky note and specific information highlighted.
The evaluation team will look at the same statement and will use the information provided to
them to rate the items. The evaluation team should make comments on any sub-section that is
rated above or less than 4.

ADVISORY COMMITTEE TASKS WITHIN PROGRAM STANDARDS
The Advisory Committee is possibly the most important tool that any automotive technician
training program can have, particularly when it is used properly and to its full extent. Regular
meetings and good documentation of the meetings in the form of minutes is a must. The
following are standards that must specifically be addressed by/with the program advisory
committee and be reflected in the minutes. In order to ensure that these items are addressed, this
document might be used as a guideline for developing an agenda for an advisory committee

TOOLS AND EQUIPMENT
Local employer needs and the availability of funds are key factors for determining each
programās structure and operation. The Program Standards recognize that not all programs have
the same needs, nor do all programs teach 100 % of the tasks. Therefore, the basic philosophy for
the tools and equipment requirement is as follows: for all tasks which are taught in the program,
the training should be as thorough as possible with the tools and equipment necessary for those
tasks. In other words, if a program does not teach a particular task, the tool from the tool list
associated with that task is not required (unless of course it is required for a task that is taught in
another area).
The tool lists are organized into three basic categories: Hand Tools, General Lab/Shop
Equipment, and Specialty Tools and Equipment. The specialty tools section is further separated
into the eight truck categories. When referring to the tools and equipment list, please note the
following:
A. The organization of the tool list is not intended to dictate how a program organizes its
tool crib or student tool sets (i.e., which tools should be in a student set, if utilized, and
which should be in the tool crib or shop area).
B. Quantities for each tool or piece of equipment are determined by the program needs;
however, sufficient quantities to provide quality instruction should be on hand.
C. For Specialty Tools and Equipment, the program need only have those tools for the areas
being accredited.
D. Programs may meet the equipment requirements by borrowing special equipment or
providing for off-site instruction (e.g., in a dealership or independent repair shop). Use of
borrowed or off-site equipment must be appropriately documented.
E. No specific brand names for tools and equipment are specified or required.
F. Although the Program Standards recommend that programs encourage their students to
begin to build their own individual tools sets prior to entry into the industry, there is no
requirement to do so. NOTE: Industry surveys indicate that most (90%) employers
require that a candidate for employment provide his/her own basic hand tool set in order
to be hired as an entry-level truck technician.

SPECIALTY TOOLS AND EQUIPMENT
WITHIN EACH ACCREDITATION CATEGORY
This section covers the tools and equipment a lab/shop should have for training in any given
specialty area. This equipment is specialized and it must be available in the lab/shop. No
specific type or brand names are identified because they will vary in each local situation.
For all tasks which are taught in the program, the training should be as thorough as possible with
the tools and equipment necessary for those tasks. In other words, if a program does not teach a
particular task, the tool from the tool list associated with that task is not required.
