The ASE A3 Manual Drive Train and Axles test is a certification exam for automotive technicians who work on clutches, transmissions, transaxles, drive shafts, and drive axles. It's administered by the National Institute for Automotive Service Excellence (ASE) and is one of the core credentials techs use to prove specialty knowledge to employers and customers.
Overview
The A3 test is organized into six content areas, each contributing a set number of questions to your scored total:
- Clutch Diagnosis and Repair
- Transmission Diagnosis and Repair
- Transaxle Diagnosis and Repair
- Drive Shaft/Half-Shaft and Universal Joint/Constant Velocity Joint Diagnosis
- Drive Axle Diagnosis and Repair
- Four-Wheel Drive/All-Wheel Drive Component Diagnosis
There's no separate road-signs or rules-of-the-road section on this test -- unlike a driver's license exam, A3 is entirely focused on technical drive-train diagnosis and repair knowledge. The test also mixes in unscored research questions alongside the scored content, so not every question you see counts toward your result.
Cost and registration
ASE charges a $62 test fee for A3, plus a $34 registration fee billed once per order regardless of how many tests you purchase at the same time. If you're recertifying and buying multiple recertification tests together, ASE caps the combined test cost at $186 per order. For the most current fee schedule, check ASE's official dates and fees page.
Exam format
The A3 test has 50 total questions, with 40 scored and the remainder as unscored research questions, and you're given 60 minutes to complete it. The recertification version is shorter: 20 questions in 30 minutes. ASE does not publish a fixed passing percentage for A3 -- scoring is scaled, so consult the official ASE study guide for details on how results are calculated.
