How ASE certification works

ASE certification is the industry-standard credential for automotive technicians in the U.S. You register for tests, sit them at a proctored test center (or via remote proctoring where offered), and the certificate is issued once your hands-on work experience is verified — relevant training can substitute for part of it.

  • Each test: $62, plus one $34 registration fee per order (2026 pricing)
  • A-series tests: 40–50 scored questions plus ~10 unscored research questions
  • Passing A1–A8 earns Master Automobile Technician status
  • Certifications stay valid for 5 years, then a shorter recertification test renews them

The best preparation is the same for every test: work through diagnostic scenarios until the symptom-to-cause reasoning is automatic. That is what these practice banks drill.

What score do I need to pass an ASE test?
ASE does not publish a fixed passing percentage — scoring is scaled. Around 65–70% correct is the commonly cited range, so aim above 80% in practice for margin.

Passing T2 through T8 earns ASE Master Medium-Heavy Truck Technician status. T1 (Gasoline Engines) is optional and not required for Master Truck.
Are these the official ASE questions?
No. These are original practice questions written from the published task-list topics, with an explanation after every answer. The official exams are administered by ASE at test centers.
