Cars and light trucks keep getting more complex, and shops need technicians who can keep up. The ASE Automobile and Light Truck certifications (A Series) give you a nationally recognized way to show employers and customers that your skills meet an industry standard.

Whether you’re a recent automotive program graduate or a seasoned tech pursuing Master status, we’ll walk you through who the A Series is for, how eligibility works, what it costs, how long it takes to study, what the career and salary outlook looks like, and where to go next.

Who Should Take the ASE A Series Exams?

The A Series is built for technicians who service passenger cars, SUVs, and light trucks. You’re a strong candidate if you work in one of these roles:

  • General service and repair technicians at dealerships, independent repair shops, and national service chains.
  • Drivability and diagnostic technicians who handle check engine lights, no-starts, and electrical concerns (A6 and A8 are natural fits).
  • Specialists such as brake and alignment techs (A4 and A5), transmission rebuilders (A2), or A/C techs (A7).
  • Fleet technicians who maintain government, utility, rental, or delivery fleets of light vehicles.
  • Automotive technology students and recent graduates who want to test while the material is fresh.
  • Light-duty diesel technicians who work on diesel pickups and vans (A9).

Because each test is its own certification, you don’t need to be an expert in everything to benefit. Many technicians start with one or two tests that match their daily work and add the rest over time.

Who Might Wait?

If you’re brand new to the trade, you can still test, but ASE won’t issue your certificate until you meet the experience requirement. If you’re looking for a first credential, ASE’s G1 Auto Maintenance and Light Repair test covers entry-level service work and can be a good starting point before the A Series.

What Are the ASE A Series Eligibility Requirements?

ASE certification has two parts: passing the test and documenting your work experience.

  • Work experience: The A Series requires two years of full-time, hands-on work experience, according to ASE Certification: What You Need to Know (2026).
  • Training substitution: Up to half of the experience requirement can be met with appropriate vocational training, such as an automotive technology program. ASE reviews each submission.
  • Timing: You can register and test before you have the experience. You’ll receive your score report, but certification is held until your experience is approved. See ASE’s work experience requirements page for the details and the submission form.

How Do You Register?

  1. Create a myASE account and submit your work experience information.
  2. Purchase the test or tests you want. Fees are a $34 registration fee per order plus $62 per certification test, per the ASE registration page.
  3. Schedule your appointment at a Prometric test center within 90 days of purchase. You can’t change an appointment within three days of the test date.
  4. Take the test and review your emailed score report.

To budget for Master status, eight certification tests at $62 each total $496, plus a $34 registration fee per order. Fees and policies can change, so check ASE’s site before you pay.

How Long Should You Study for the ASE A Series?

Because you take the tests one at a time, plan for each test rather than the whole series. A realistic range is two to six weeks per test, depending on how closely the test matches your daily work.

  • Experienced technicians testing in their specialty, such as a brake tech taking A5, often need two to three weeks of focused review on less familiar components, specifications, and ASE’s question style.
  • Newer technicians or those testing outside their specialty should plan four to six weeks, with extra time for heavily weighted areas like A6 Body Electrical (17 questions) or A2 diagnosis (26 questions).

Sample Plan for Master Automobile Technician Status

If you’re working toward A1 through A8, spacing tests about a month apart is a sustainable pace. One sample path:

  • Month 1: A5 Brakes. Familiar work for most techs and a confidence-building first pass.
  • Month 2: A4 Suspension and Steering. Alignment angles, tire wear, and steering diagnosis.
  • Month 3: A1 Engine Repair. Compression, leakage, and mechanical engine diagnosis.
  • Month 4: A6 Electrical/Electronic Systems. Voltage drop, schematics, and network diagnosis. These skills support every test that follows.
  • Month 5: A8 Engine Performance. Builds directly on A1 and A6 with fuel trim, OBD II monitors, and emissions systems.
  • Month 6: A7 Heating and Air Conditioning. Refrigerant cycle, pressure readings, and HVAC controls.
  • Month 7: A3 Manual Drive Train and Axles. Clutches, transaxles, CV joints, differentials, and 4WD/AWD.
  • Month 8: A2 Automatic Transmission/Transaxle. Pressure testing, electronic shift controls, and in-vehicle service.

Within each month, take a baseline quiz in week one, work through weak content areas in weeks two and three, and finish with timed mixed practice in week four.

What Careers Can the ASE A Series Support?

A Series certification supports roles such as automotive technician, drivability or diagnostic technician, transmission specialist, A/C technician, fleet technician, shop foreman, and service manager. Many employers list ASE certification as preferred or required, and some tie pay increases or promotions to how many certifications you hold.

Common employers include new car dealerships, independent repair shops, tire and service chains, rental and government fleets, and automotive training programs.

Certification also helps you move up. Master technicians are often the ones considered for lead tech, shop foreman, or instructor roles, where you’ll mentor newer technicians and handle the toughest diagnostic jobs.

What Is the Salary for Automotive Technicians?

According to the BLS Occupational Outlook Handbook, automotive service technicians and mechanics earned a median annual wage of $50,620 ($24.34 per hour) in May 2025. Median pay by industry included:

  • Automobile dealers: $59,920
  • Automotive mechanical and electrical repair and maintenance: $49,630
  • Automotive parts, accessories, and tire retailers: $45,700

The BLS projects 5% employment growth from 2025 to 2035, faster than the average for all occupations, with about 66,200 openings each year. The BLS also notes that industry certifications demonstrate competence and may lead to higher pay. Actual earnings depend on your region, employer, pay structure, and specialty.

How Do You Maintain ASE A Series Certification?

ASE certifications are valid for five years, and Master status lasts only as long as each required certification stays current. For the A Series, you have three ways to renew:

  • Recertification tests: About half the length of the original. For example, the A6 recertification test has 25 questions in 45 minutes, and A1 has 23 questions in 30 minutes. Each costs $62, with a $186 cap on recertification test fees per order.
  • Remote testing: Recertification tests can be taken online through Prometric’s live-proctored remote option, as long as you have a secure testing space.
  • ASE Renewal App: Available for A1-A9 at $52 per year. The app delivers new questions every 30 days for each eligible certification, and earning eight credits extends that certification’s expiration date by one year.

You’re eligible for a recertification test only if you previously passed the full certification test in that area, even if your certification has since expired.

What Certifications Stack Well With the ASE A Series?

  • ASE L1 Advanced Engine Performance Specialist: The next step for drivability techs. You must pass A8 before you can register.
  • ASE L3 Light Duty Hybrid/Electric Vehicle Specialist: Requires passing A6 and A8 first, and it’s increasingly valuable as hybrids and EVs fill service bays.
  • ASE xEV High-Voltage Electrical Safety certifications: xEV Level 1 and xEV Level 2 safety credentials for anyone who works around high-voltage systems.
  • EPA Section 609 certification: Required under the Clean Air Act to service motor vehicle A/C systems for pay, and a natural partner to A7.
  • ASE C1 Automobile Service Consultant: A good fit if you’re moving toward the service counter or management.
  • ASE T Series: A logical expansion if your shop or fleet also services medium- and heavy-duty trucks.
