What Are the ASE A-Series (A1–A9) Tests?

Oct 16, 2026

The ASE A-series is the set of automobile and light truck tests that working technicians take to earn ASE certification in specific areas. Each area is a separate test, so you choose which ones to take and when. ASE also has requirements beyond passing the test, including hands-on work experience. Official details on the tests, experience requirements and registration are at ase.com.

The 9 A-series areas

A-series vs. Entry-Level

The Entry-Level tests are for students and people new to the trade, usually taken through a school or training program. The A-series tests are for working techs. Both follow published task lists, but the A-series expects deeper diagnostic thinking.

Which area should you take first?

Many techs start with the work they do most. A5 Brakes and A4 Suspension & Steering are common first choices. Electrical (A6) and Engine Performance (A8) build on each other, so it can help to study them back to back.
