What ASE Certification Is and How to Earn 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. It does not come from your employer, your state, or a training program — it comes from passing an exam administered by ASE itself. The test covers the knowledge and skills that technicians in that specialty are expected to have.
To earn an ASE certification, you take a computer-based exam at a testing center, answer questions about diagnosis, repair, and maintenance in your chosen area, and receive a score. If you pass, ASE issues you a certificate and a wallet card. You do not need to attend a school, pay a training company, or work for a specific shop — you only need to meet the experience requirement and pay the exam fee.
ASE offers separate certifications for different vehicle systems and specialties: engine repair, automatic transmission, manual drivetrain, suspension and steering, brakes, electrical systems, heating and air conditioning, engine performance, light vehicle diesel engines, and several others. You can take one test or all of them. Many technicians earn multiple certifications over time.
Key Takeaways
- You must have at least two years of hands-on work experience in the area you want to test, or one year of experience plus completion of a relevant training program.
- You register and pay for the exam through the ASE website, then schedule a test date at a local testing center.
- The exam costs between $150 and $200 per test, depending on which certification you are pursuing.
- You receive your score when ready after the exam, and ASE mails your certificate within a few weeks if you pass.
- ASE certifications are valid for five years, after which you must retake the exam to keep the credential current.
Experience Requirements Before You Test
ASE requires documented work experience in the area you want to test. The standard requirement is two years of hands-on experience as an automotive technician in that specialty. This means time spent actually diagnosing, repairing, or maintaining vehicles — not administrative work, parts ordering, or vehicle inspection alone.
If you have completed a formal training program in that area, you can reduce the experience requirement to one year. A formal program means a course offered by a trade school, community college, or manufacturer training center that covers the topics on the ASE exam. Online courses do not count as formal training for this purpose.
You do not need to work at the same shop for the full two years, and you do not need your employer's permission to test. You track your own experience and declare it when you register. ASE does not verify experience before you take the exam — it verifies it only if you pass and ASE suspects the claim is false.
How to Register and Schedule Your Exam
Registration happens on the ASE website at ase.com. You create an account, select which certification test or tests you want to take, and pay the exam fee for each one. You can take multiple tests on the same day or on different days — that choice is yours.
After you pay, you receive a registration confirmation with a code. You then go to the testing center locator on the ASE website, find a center near you, and schedule your test date. Most areas have multiple testing centers, and you can usually find an available date within a few weeks. Testing centers are run by Pearson VUE, a third-party testing company, and are located at various facilities including community colleges, vocational schools, and testing offices.
Bring a valid government-issued photo ID to the testing center. You cannot bring study materials, phones, or notes into the testing room. The exam is computer-based and takes about 90 minutes per test.
What the Exam Covers and How to Prepare
Each ASE exam contains between 40 and 80 multiple-choice questions covering diagnosis, repair procedures, tools, safety, and troubleshooting in that specialty. The questions are based on real-world scenarios technicians encounter. For example, a brakes exam question might describe a vehicle symptom and ask you to identify the most likely cause and the correct repair procedure.
ASE publishes a test content outline for each certification on its website. This document lists the topics and subtopics the exam will cover, so you know exactly what to study. You can read it free from ase.com.
To prepare, you can study on your own using the test outline, textbooks, and online resources. ASE does not offer official study courses, but many training companies, YouTube channels, and textbook publishers offer ASE prep materials. Some shops provide study time or materials to technicians preparing for the exam. The amount of preparation you need depends on how much hands-on experience you already have — someone with five years in the field may need less study time than someone with exactly two years.
Exam Fees and Certification Validity
Each ASE exam costs between $150 and $200. The exact price varies slightly by test type and can change year to year. You pay when you register, and the fee is non-refundable if you miss your test date without canceling at least 24 hours in advance.
If you pass, ASE sends you a certificate and wallet card in the mail within a few weeks. Your certification is valid for five years from the date you pass the exam. After five years, your certification expires, and you must retake the exam to renew it. You do not have to pay a renewal fee — you straightforward take the exam again.
While your certification is active, you can display it on your resume, business cards, and shop signage. Many employers prefer or require ASE certification for technician positions, and some shops advertise that their technicians are ASE-certified as a selling point to customers.
What Happens If You Do Not Pass
If you fail the exam, you receive a score report showing which topic areas you did not perform well on. You can retake the exam as many times as you need. Each retake requires a new registration and another exam fee.
Most people who fail study the weak areas and retake the exam within a few weeks or months. There is no waiting period between attempts, and you can register for a new test date when ready after receiving your score.
ASE Certification vs. Other Credentials
ASE certification is the most widely recognized credential in the automotive service industry, but it is not the only one. Some manufacturers, such as Ford, General Motors, and Toyota, offer their own technician certifications. Some states require a license for certain types of work, such as emissions testing or air conditioning service. Trade schools and community colleges offer diplomas and degrees in automotive technology.
ASE certification is independent of all of these — you can have an ASE certification, a manufacturer certification, a state license, and a trade school diploma all at the same time. Many technicians pursue multiple credentials to show broader informed and increase their job prospects. ASE is often the first credential technicians pursue because it is standardized across all shops and employers.
Frequently Asked Questions
Can I take the ASE exam without any work experience?
No. ASE requires at least two years of hands-on work experience in the area you want to test, or one year of experience plus completion of a formal training program. You cannot test without meeting one of these requirements.
What if I worked in automotive service but not in the specific area I want to test?
ASE counts only hands-on experience in the specific area. If you worked in general maintenance but want to test for transmission repair, you would need two years specifically in transmission work. Some experience may transfer if it overlaps significantly, but ASE makes the final information.
How long does it take to get my certificate after I pass?
ASE mails your certificate and wallet card within a few weeks of passing. You receive your score when ready at the testing center, so you know right away whether you passed, but the physical certificate takes time to arrive.
Do I have to renew my ASE certification?
Your certification is valid for five years. After that, it expires. You can renew it by retaking the exam. There is no separate renewal fee — you straightforward register and pay the exam fee again, just as you did the first time.
Can I test for multiple ASE certifications at once?
Yes. You can register for multiple exams and take them on the same day or different days. Each test requires a separate registration and fee, but there is no limit to how many you can pursue.
