ASE certification FAQ
Short, honest answers to the questions technicians ask most. Where a figure is still being verified against the official source, we say so rather than guess.
Common questions
Does ASE certification increase pay?
No public dataset isolates a wage premium specific to ASE certification versus the broader occupation. What is sourced: the U.S. Bureau of Labor Statistics puts the 2025 median wage for automotive service technicians and mechanics nationally at $50,620 a year, and many employers separately state a hiring or pay-scale preference for ASE-certified technicians.
How do I track multiple ASE certification expiration dates?
Every ASE certification runs on its own independent 5-year clock starting the date you earned it, so a technician with six certs is juggling six separate deadlines. This site's free recert tracker holds every cert's earn date in your browser and sorts them by nearest deadline.
How long is an ASE certification valid before it expires?
Every ASE certification is valid for 5 years from the date you earn it, and each certification you hold runs on its own independent 5-year clock rather than one shared account-wide expiration date. You can renew by retesting at any time, and A1-A9 holders can also renew through the paid ASE Renewal App.
How many ASE certifications are there?
ASE currently administers 45 civilian certification tests you can pursue on this site's matrix, across ten series (A, B, C, F, G, H, L, P, S, T), plus a separate military program. That count excludes L1, which uses proprietary composite-vehicle materials this site does not cover.
How many questions are on an ASE recertification test?
An ASE recertification retest usually runs about half the question count and time of the original certification exam. A1's 45-question initial test becomes a 23-question recert version, for example, though the exact recert length varies test by test and is published on each individual test's ASE page.
How much does ASE certification cost?
Every ASE test in the General category costs $62. The Advanced Level specialist tests, L2, L3, and L4 (L1 excluded), cost $124 each. Every order also carries a flat $34 registration fee, and no single order can exceed $220 total no matter how many tests it includes.
My ASE certification expired. Now what?
It is not permanently lost. ASE states directly that you may take the recertification test even after your credentials have expired, no hard cutoff, and that retest usually runs about half the length of the original exam. If the expired certification is A1-A9, the $52/year ASE Renewal App is also an option instead of retesting.
What are the requirements for ASE L4 ADAS certification?
ASE L4 covers Advanced Driver Assistance Systems (ADAS) and requires 3 years of full-time hands-on relevant experience, a $124 Advanced Level test fee, and passing a 50-question, 120-minute exam. As ASE's newest specialist test, its recertification cadence was not confirmed in ASE's published recert-fee breakdown as of this site's last verification pass.
What are the requirements for ASE Master Automobile Technician status?
ASE Master Automobile Technician status requires passing all eight A-series tests, A1 through A8, plus meeting each individual test's own work-experience requirement. A9 (Light Vehicle Diesel Engines) is a separate, optional add-on and is not required for Master status; ASE does not require the eight tests be passed in any particular order.
What does ASE stand for?
ASE stands for the National Institute for Automotive Service Excellence, the organization that administers the 45 in-scope specialty certification tests this site maps, covering automotive, truck, collision, and bus technicians. ASE certification is voluntary, not a government license, and this site is an independent reference, not affiliated with or endorsed by ASE.
What's the best entry-level ASE certification for beginners?
G1 (Auto Maintenance and Light Repair) is ASE's entry-level generalist test, requiring 1 year of experience versus the 2 years most A-series tests require, and it samples lightly across engine, brakes, electrical, and HVAC systems rather than testing one system in depth.
What's the difference between ASE A-series and T-series certifications?
A-series certifications (A1 through A9) test automobile and light-truck systems, while T-series certifications (T1 through T8) test medium- and heavy-duty truck systems instead. They are separate credential tracks scoped to different vehicle classes: passing A-series tests does not certify you on trucks, and passing T-series tests does not certify you on cars.
Which ASE certification is right for collision repair work?
Collision repair technicians start in the B-series, not the A-series: B2 covers painting and refinishing, B3 covers non-structural analysis and damage repair, B4 covers structural analysis and damage repair, B5 covers mechanical and electrical components, and B6 covers damage analysis and estimating for an estimator role rather than hands-on repair.
Which ASE certification should I get first?
There is no single right first test. It depends on what you actually work on: a general automotive repair technician usually starts with G1 or A5 (Brakes), a collision technician starts in the B-series, and a truck technician starts in the T-series. The which-test wizard maps your role to the right starting point.
