What ASE Certification Is and Why You Need It
ASE certification is a credential issued by the National Institute for Automotive Service Excellence that shows you have passed a standardized test in a specific area of vehicle repair or service. Employers use it to verify you know your trade — it is not required by law in most states, but many shops will not hire you without it, and customers often ask for ASE-certified technicians by name.
The certification covers eight main areas: engine repair, automatic transmissions, manual drivetrains, suspension and steering, brakes, electrical systems, heating and air conditioning, and engine performance. You can test in one area or all eight. Each test is separate, and you pay for each one you take.
ASE also offers certifications for collision repair, truck service, school bus maintenance, and other specialties, but the eight automotive areas are the most common path for technicians working at dealerships and independent shops.
Key Takeaways
- You must have two years of hands-on work experience in the area you want to test, or one year of experience plus a relevant degree or diploma from a technical school.
- You register and pay for each test through the ASE website; tests cost around $150 each and are given year-round at testing centers in your area.
- Each test has 40 to 80 multiple-choice questions and you have 45 to 60 minutes to complete it, depending on the test.
- You must score at least 70 percent to pass, and results are available when ready after you finish.
- Your certification lasts five years, then you must retake the test to renew it.
Meet the Work Experience Requirement
Before you can register for an ASE test, you must prove you have worked in that specific area. The standard requirement is two years of full-time hands-on experience — meaning you spent at least 30 hours per week actually doing the work, not just watching or helping.
If you attended a technical school or community college with an automotive program, you can reduce this to one year of experience. The school must be accredited by the National Automotive Technicians Education Foundation (NATEF) or a similar recognized body. When you register, you will upload a transcript or diploma as proof.
Your employer does not have to sign off on your experience, but ASE may contact them to verify your hours if your process is flagged. Keep records of your job titles, dates, and the types of work you did — this makes verification faster if it happens.
Register for Your Test on the ASE Website
Go to ase.com and create an account. You will enter your name, contact information, and work history. For each test you want to take, you will select the specific area (engine repair, brakes, electrical systems, and so on) and choose a testing center near you.
ASE tests are offered year-round at hundreds of testing centers across the country — usually at technical schools, community colleges, or testing facilities. When you register, you can see which centers near you have open dates and times. You can schedule your test weeks in advance or as soon as a few days out, depending on demand in your area.
The registration fee is approximately $150 per test as of 2024, though this may vary. You pay when you register, and ASE will send you a confirmation email with your test date, time, and location. You can register for multiple tests at once or space them out over weeks or months.
Prepare for the Test Content and Format
Each ASE test covers the knowledge and skills used in that specific area of automotive work. For example, the brakes test includes questions about drum brakes, disc brakes, hydraulic systems, and brake diagnostics. The electrical systems test covers batteries, starters, alternators, wiring, and lighting.
ASE publishes a test content outline for each certification area on their website — this is a detailed list of topics the test covers. You can read it for free and use it to study. The outline tells you what percentage of the test focuses on each topic, so you know where to spend your study time.
Tests are multiple-choice with four answer options. You have 45 to 60 minutes depending on the test, and you take it on a computer at the testing center. You cannot bring notes, calculators, or reference materials into the testing room. You will see your score when ready after you finish, and a detailed score report will be mailed to you within two weeks.
Study Materials and Preparation Options
ASE does not provide official study guides, but many publishers sell ASE prep books and online courses. Common options include study guides from Delmar Cengage, Pearson, and Motor Age Training. These books walk through each topic on the test outline and include practice questions. Prices range from $30 to $100 depending on the format and publisher.
Some technical schools and community colleges offer ASE prep courses — these are usually short, focused classes that meet for a few weeks before test dates. Your employer may also offer study time or materials if they encourage technicians to get certified. Ask your manager or training department what resources they have.
Online practice tests are another option — websites like ASE Study Guides and other third-party sites offer sample questions for a fee. These let you practice under timed conditions and see which topics you need to review more. Many people combine a prep book with practice tests to build confidence before test day.
What Happens After You Pass
Once you pass a test, ASE will mail you a certificate within four to six weeks. Your name and test results are also added to the ASE registry, which employers can search to verify your certification. You can request wallet cards or additional certificates if you need them for job applications.
Your certification is valid for five years from the date you pass the test. To keep it active after five years, you must retake and pass the test again. Some employers require you to maintain current certification as a condition of employment, so mark your renewal date on your calendar.
If you pass multiple tests, you can earn the title ASE Certified Master Technician — this requires passing at least four of the eight main automotive tests plus meeting work experience requirements. Many shops display this credential prominently because it signals a high level of skill.
Retesting If You Do Not Pass
If you score below 70 percent, you do not pass and do not receive a certificate. You can retake the test as many times as you need to, but you must pay the full registration fee each time. There is no waiting period between attempts — you can register for the same test again when ready if you want to.
When you retake a test, review the topics where you scored lowest. Use the test content outline to focus your study, and consider working through practice questions or a prep book again before your next attempt. Many people pass on their second or third try after more focused preparation.
Frequently Asked Questions
Do I need a high school diploma or GED to get ASE certified?
No, ASE does not require a diploma or GED. You only need to meet the work experience requirement — two years of hands-on work in the area you want to test, or one year plus a technical school diploma. Your education level does not matter as long as you have the experience.
Can I test in multiple areas on the same day?
Yes, you can register for multiple tests on the same day at the same testing center. Most people take one or two tests per day to avoid fatigue, but the choice is yours. Each test is separate and you pay for each one.
What if I move to a different state after I get certified?
ASE certification is recognized nationwide — your certificate is valid in every state. You do not need to retest or register again if you move. Your certification remains in the ASE registry and employers in your new state can verify it the same way.
How much does ASE certification cost in total?
Each test costs around $150, so if you test in all eight automotive areas, the total would be approximately $1,200. You do not have to test in all eight at once — many technicians test in one or two areas first, then add more over time as they gain experience in those areas.
Can I study while I work, or do I need to take time off?
You can study on your own time outside of work — most people use evenings and weekends to prepare. You only need to take time off for the actual test day, which is usually a few hours at the testing center. Some employers give paid time off for testing, so ask your manager.
