Four Testing Windows per Year

ASE certification testing is offered in four testing windows throughout the year. For instance, the Fall testing window runs from October 1 through November 30. There are two steps prior to taking an ASE test: registration and scheduling. You can register for testing during most of the testing window. Once you have registered, you can schedule testing appointments throughout the window. All tests are administered during the second and third months of the testing window. You can view a full schedule for the current year here.

Separate Registration and Test Fees

To register, you (or your employer) select the tests you want to take, and pay for those tests. If this is the first time you are purchasing tests in the current testing window, you are charged a $36 per person registration fee, in addition to the test fee ($31 each for most tests.) If you (or your employer) have already paid the registration fee during this testing window, then you can register for additional tests and only pay the additional test fee. You can view the complete list of tests and fees here.

Three-Day Grace Period

In general, if you purchase a test or make an appointment and then change your mind, you have three days to cancel without any penalty. Additional details and conditions are listed below. To avoid forfeiting your fees, all changes must be made at least three days prior to your scheduled appointment.

One Test Attempt Per Testing Window

If you take an ASE test and receive a “Pass” or “Fail” test result, you may not register to take that same test again during the same testing window. However, you can register and take other ASE tests you have not yet attempted in the current testing window. If you fail a test in the current testing window, you can take it again in future testing windows, but you must pay the registration and test fees again.

Missed Tests

There are no refunds or credits for missed testing appointments. If you miss a test, you can register for that same test again in the same testing window, but you must pay the test fee again. To re-register, you must wait until the official “No Show” test result for the missed test is posted to myASE. When you re-register for a missed recertification test, the recertification test fee cap does not apply. You must pay the recertification test fee again.

Testing Appointments Required

All ASE certification tests are delivered at secure, proctored test centers through ASE’s testing partner Prometric. You should schedule appointments for all tests as soon as possible and complete all testing by the end of the testing window. In most cases, the earliest you can test is three days after you make the appointment. If you are taking more than one test, you can group them together into a single appointment, or spread them out over several appointments. The day, time, and grouping is up to you.

To make an appointment at a Prometric test center, go to myASE or call Prometric at 1-877-346-9327. If you plan to test at a Prometric Satellite test center, you should call that test center directly to schedule your test. You can find the closest centers using our test center locator.

Unscheduled Tests Roll Over One Time

If you do not schedule an appointment to take a test in the testing window in which it was purchased, the test will “roll over” one time to the following testing window. You must schedule an appointment and take it in that testing window. At the close of that testing window, all untaken tests expire and you will forfeit your fees.

Arrive Early

Plan to arrive 30 minutes before the scheduled appointment to allow time for check-in. If you arrive late, you may not be allowed to test and will forfeit your fees.

Bring Your Photo ID With Signature

You will need to present one valid, unexpired government-issued photo ID with a signature. The name on your ID must match the name on your ASE record (shown above.) If you are testing outside of your country of citizenship, you must present a valid passport. Otherwise, you must present a valid passport, driver's license, state or national ID, or military ID. If you do not bring an acceptable ID, you will not be allowed to test and will forfeit your fees.

All other personal items, including cell phones, must be placed in a locker for test security purposes, so please limit what you bring to the test center. You will be checked with a metal detector before you enter the testing room. If you do not comply with the directions of the test center staff and Prometric security regulations, you will not be allowed to test and will forfeit your fees.

Composite Vehicles Used On the L1 and L2 tests

If you are taking an L1 or L2 Advanced Level test (regular or recertification), you should download copies of the Test Information and Composite Vehicle booklets here and become familiar with the content prior to your test date. You will be provided with a printed copy of the Composite Vehicle Booklet at the test center.

Appointment Changes

If you wish to change your test date or time, you may do so within 3 days of scheduling the appointment without penalty. After 3 days, there is a $20 fee for cancelling an appointment. The person who cancels the appointment is responsible for the cancellation fee. No changes are allowed within 3 days of your scheduled appointment.

To make changes, use the Cancel Appointment option in myASE, or call Prometric at 1-877-346-9327. The web is available 24 hours a day, 7 days a week. There is no fee for scheduling a new appointment.

There are no refunds or credits for missed testing appointments. If you miss your appointment or arrive late, the tests are scored as “No Show”, and you forfeit all fees.

Severe Weather

In the event of severe weather or disaster, we may need to cancel your appointment. If this happens, Prometric will attempt to contact you by telephone and/or e-mail. If there is a possibility of severe weather and you are in doubt, call Prometric at 1-877-346-9327. If the test center is open, it is your responsibility to keep the appointment. If the test center is closed, your tests will be rescheduled at your earliest convenience, without any additional fee.

Test Center Problems

On rare occasions, technical difficulties may occur at the test center. Every effort will be made to correct those problems as soon as possible. In most cases, you will be able to resume your test where you stopped, with no reduction in the testing time. If the problem cannot be corrected within 30 minutes, you can reschedule your appointment to another day, without any additional fee. If a test is rescheduled, you must take the entire test over from the beginning.

There are no refunds or any other compensation for any expenses or losses associated with any case where tests cannot be administered as scheduled. A rescheduled appointment is the only remedy available.

Score Reports

Score reports are normally provided at the testing center when you complete the tests. Technical problems may prevent the test center from providing a score report. Test scores are usually posted to myASE within 3 days of the test, but occasionally, scores may be delayed.

Canceling Tests

If you wish to cancel a test, you must first cancel any existing appointment for that test, and then cancel the test itself. Use the Cancel Test option in myASE, or call Prometric at 1-877-346-9327. The web is available 24 hours a day, 7 days a week. If you are within 3 days of your testing appointment, you cannot cancel the appointment or test.

You can only cancel tests for which you paid. If you cancel a test within 3 days of purchase, you will receive a refund. Otherwise, you will receive a credit that can be used to pay for other ASE certification tests and fees. Credits must be used by the expiration date shown in myASE.

Test Takers With Disabilities

ASE provides reasonable testing accommodations to qualified individuals with a documented professional diagnosis at no additional cost under the provisions of the Americans with Disabilities Act (ADA). If you have a disability and wish to receive testing accommodations, you must submit your request and be approved before you register for the tests. The process is fully explained here. Note that English as a Second Language by itself does not qualify as a disability under ADA, and ASE no longer offers the Reader/Translator option.

Bilingual Tests

ASE no longer offers bilingual tests, but an English-Spanish glossary of technical terms can be accessed on each question in all tests by clicking a button on the computer screen.

Release of Test Results and Certification Status

If your employer or school paid for your test, they will be able to view the pass/fail/no-show test result, but not the specific test score. If you paid for the test yourself, only you can see the pass/fail/no-show test result, in addition to the specific test score. You can reprint a score report in myASE at any time.

ASE does reserve the right to confirm whether you do or do not hold ASE certifications and in which areas. This is information about only those tests that you have passed - basically, it is the same information that is on your wall display certificate. If you do not want ASE to share this information with anyone else, you can opt out by unchecking the box labeled “Release my ASE status to others” in your profile in myASE. If you do so, ASE will not release your certification status to your employer, OEM, or other group or individual. This may prevent you from being reimbursed for tests, participating in recognition programs, or accessing service information, etc.

Notice to Organizations Using the ASE Examinations

The National Institute for Automotive Service Excellence (ASE) has developed these certification examinations expressly for use in the context of voluntary certification of vehicle service professionals, and all future revisions and refinements will be made in that context. ASE expressly disclaims any responsibility for the actions of organizations or entities which decide to use ASE examinations in any context other than ASE's voluntary certification of vehicle service professionals.

The Institute reserves the right to cancel any test score, bar participation in the ASE Program, or revoke certification if ASE has any reason to question the validity of a test score, suspect misconduct at the Test Center, suspect an individual of creating or presenting fraudulent ASE certificates, score reports, or other credentials, or suspect the reporting of fraudulent registration information.

Terms and Conditions May Change

These terms and conditions are subject to change without notice. By registering for ASE certification tests and/or scheduling testing appointments, you agree to these terms. If you enter a registration or schedule an appointment on behalf of someone else, you certify that each person registered or scheduled accepts these terms as well.
