ASE G1 Auto Maintenance and Light Repair Certification Test Exam Guide

The G1 exam draws every question from seven weighted content areas covering the core systems a maintenance and light repair technician works on day to day. There is no separate signs or rules section here; instead, the test blends all seven areas into one timed exam, with heavier weighting on the systems technicians encounter most often.

• Engine Systems — 9 questions
• Automatic Transmission/Transaxle — 4 questions
• Manual Drive Train and Axles — 6 questions
• Suspension and Steering — 13 questions
• Brakes — 11 questions
• Electrical — 8 questions
• Heating, Ventilation, and Air Conditioning — 4 questions

The G1 test fee is $62, and ASE charges a separate $34 registration fee per order on top of that. For any other current pricing details or bundled test discounts, check ASE's official fee schedule.

The initial G1 test has 55 total questions, of which 45 are scored, with a 90-minute time limit. Technicians must retest every five years to keep their certification current; the recertification version is shorter, with 28 questions and a 45-minute time limit. Candidates also need 1, 2, or 3 years of relevant work experience, depending on the certification pathway, before they're eligible to test.
