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 test in a specific area of vehicle repair or service. Employers use it to verify you know your trade. You do not need ASE certification to work on cars — many shops hire without it — but most dealerships and larger repair shops require at least one ASE credential before they will hire you as a technician, and many pay more once you have it.

ASE offers separate tests for different specialties: engine repair, transmission, brakes, suspension, electrical systems, heating and air conditioning, and others. You can take one test or all eight. Each test costs money and requires you to pass on your own — there is no course you must take first, though many people take one anyway.

Key Takeaways

  • You must have two years of hands-on work experience in the area you want to test in, or one year of experience plus a high school diploma or equivalent in automotive technology.
  • You register and pay for tests through the ASE website, then take the exam at a testing center — not online, not at your workplace.
  • Each test costs between $150 and $200, and you get your score the same day you finish.
  • Your certification lasts five years, then you must retake the test to keep it current.
  • You can take multiple tests on the same day or spread them out over months or years.

Check Your Work Experience Before You Register

ASE requires proof that you have actually worked on vehicles. You cannot test without it. The requirement is either two years of full-time work experience in the area you want to test, or one year of experience plus a high school diploma or equivalent (GED) in automotive technology.

Full-time means at least 30 hours per week. If you worked part-time, the hours add up — 15 hours per week for four years counts as two years of full-time experience. You do not need to have worked at the same shop the whole time. ASE counts experience across multiple employers.

When you register, you will enter your work history. ASE may contact your former employers to verify. If you cannot document the required experience, you will not be allowed to test. If you are short on hours, you can wait until you have enough, or you can look for a high school or community college automotive program that will count toward the requirement.

Create an ASE Account and Register for Your Test

Go to the ASE website (ase.com) and create an account. You will need an email address and a password. Once you are logged in, you can view all eight test categories and choose which one you want to take first.

When you select a test, you will enter your work history. Be specific: list the shop name, your job title, the dates you worked there, and the number of hours per week. ASE uses this information to confirm you meet the experience requirement. If you have a high school diploma or automotive technology degree, upload an image of it.

After you submit your history, ASE will review it — this usually takes a few business days. Once approved, you can pay the test fee (typically $150 to $200 per test) and schedule your exam at a testing center near you. Testing centers are located in most cities and are run by Pearson VUE, the company that administers the exam.

Prepare for the Test and Schedule Your Exam Date

Each ASE test has 40 to 80 multiple-choice questions, depending on the category. You have 45 minutes to an hour to finish. The test covers real-world scenarios — you might see a photo of a part or a description of a symptom and have to choose the correct diagnosis or repair.

ASE publishes study guides and sample questions on its website for free. Many people also buy study books from publishers like Delmar or ASE itself, or watch videos on YouTube. You do not have to take a prep course, but some people find one helpful, especially if they have been out of school for a while. Community colleges and trade schools often offer ASE prep courses, sometimes for free if you are enrolled.

Once you are ready, log back into your ASE account and select a testing date and location. You can usually find an appointment within a week or two. Bring a valid photo ID and arrive 15 minutes early. You cannot bring study materials, phones, or notes into the testing room.

Understand Your Score and What Happens Next

You will see your score when ready after you finish the test. ASE tells you whether you passed or failed, but not the exact percentage. A passing score is typically around 70 percent, though it varies slightly by test. If you pass, your certification is issued right away and you can read a digital certificate to show employers.

If you fail, you can retake the test as many times as you need to. There is no waiting period between attempts, but you have to pay the fee each time. Most people who fail study the weak areas and try again within a month or two.

Your certification is valid for five years from the date you pass. After five years, you must retake the test to renew it. You do not have to take the same test — you can switch to a different specialty if your work has changed — but you do have to pass something to stay certified.

Build Your Credentials Over Time

Most technicians do not get all eight ASE certifications at once. You might start with the test that covers your main job duty — an engine specialist might start with engine repair, for example — and add more over time as you gain experience in other areas.

Once you have passed at least one test, you can use the title ASE Certified Technician. If you pass all eight tests, you become an ASE Master Technician. Some employers offer bonuses or raises when you reach Master status. Others straightforward require one or two specific certifications for the job you do.

You can take tests in any order and at any pace. Some people take two or three in a year; others spread them out over several years. The only rule is that you must renew each one every five years by retaking the test.

Frequently Asked Questions

Do I have to take a prep course before I test?

No. ASE does not require any formal training. You can study on your own using free materials from the ASE website, buy a study book, or take a course — it is your choice. Many people pass without a course, especially if they have solid work experience in that area.

Can I take multiple tests on the same day?

Yes. You can schedule up to four tests in a single day at the same testing center, though most people take one or two at a time. Each test is separate and costs its own fee.

What if I fail a test?

You can retake it when ready — there is no waiting period. You pay the fee again and schedule another appointment. Most testing centers have openings within a week or two. There is no limit to how many times you can attempt a test.

Does ASE certification transfer between states?

Yes. ASE certification is national and recognized everywhere in the United States. Your credential is the same whether you work in California or New York. Some states also have their own licensing requirements for technicians, but ASE is separate from those.

How much does it cost to get all eight certifications?

Each test costs between $150 and $200, so eight tests would cost roughly $1,200 to $1,600 total. You do not have to take them all at once — you can spread the cost over several years as you gain experience in different areas.
