ASE G1 Frequently Asked Questions
What does ASE G1 stand for?
ASE G1 stands for ASE Auto Maintenance & Light Repair (G1). It is administered by ASE.
Who administers the ASE G1?
The ASE Auto Maintenance & Light Repair (G1) (ASE G1) is administered by ASE. For official information, visit the ASE website.
How many questions is the ASE G1?
The ASE G1 consists of 55 questions. Candidates are given 60 minutes to complete the exam.
What is the passing score for the ASE G1?
The passing score for the ASE G1 is Not disclosed, as set by ASE. Scoring methodology and passing standards may be updated periodically. Always verify current requirements with the governing body.
How much does the ASE G1 exam cost?
The ASE G1 exam fee is $36 USD. This fee is set by ASE and may vary by testing centre, region, or membership status. Additional fees for registration or rescheduling may apply.
Who should get ASE G1?
ASE G1 is designed for entry-level automotive technicians — lube technicians, quick service technicians, and service advisors who perform or oversee basic maintenance tasks. It is also appropriate for students in automotive technology programs as a gateway credential. G1 is intentionally broad and accessible, covering everyday maintenance tasks rather than advanced diagnosis and repair.
Does ASE G1 count toward Master Tech status?
No — ASE G1 is separate from the A-Series credentials and does not count toward ASE Master Automobile Technician status. Master Tech requires passing all 9 A-Series tests (A1–A9). G1 is a standalone entry-level credential. However, G1 prepares technicians for A-Series tests by building foundational maintenance knowledge.
What experience is required for ASE G1?
ASE G1 requires only 1 year of relevant maintenance experience — lower than the 2-year requirement for A-Series tests. This makes it ideal for technicians in their first year at a quick-service or lube shop. Automotive technology program graduates may qualify for experience credit, making G1 accessible even before formal employment.
What is a multi-point inspection and how is it tested on G1?
A multi-point vehicle inspection (MPI) is a systematic check of a vehicle's key systems during a maintenance visit — typically checking fluid levels, brake pad thickness, tire tread depth and pressure, battery condition, belts, hoses, lights, and wiper blades. G1 tests proper inspection procedure, how to communicate findings to service advisors, and how to identify items needing immediate attention vs. monitoring.
How difficult is the ASE G1 exam and what pass rate can I expect?
The ASE G1 (Auto Maintenance and Light Repair) exam is considered entry-level compared to the A-Series tests. Pass rates are generally higher, often in the 70–80% range, since the content focuses on routine maintenance tasks rather than complex diagnosis.
What are the eligibility requirements for ASE G1 certification?
Like all ASE certifications, passing the G1 exam alone does not award certification. You must document at least one year of relevant work experience in maintenance and light repair. Some training program completions can partially satisfy the experience requirement.
How long should I study to pass the ASE G1 exam?
Two to four weeks of focused preparation is typical for most candidates. The G1 covers oil changes, fluid checks, belts, filters, tires, and basic electrical tasks — all areas that on-the-job experience reinforces well.
What jobs does the ASE G1 certification open up?
The G1 is ideal for quick-lube technicians, service advisors who need a credential, and entry-level shop technicians. It signals competence in routine maintenance and positions holders for advancement toward the full A-Series.
What is the ASE G1 retake policy if I fail?
A 30-day waiting period applies before retesting after a failed attempt. Candidates must pay a new registration fee for each attempt.
How long does the ASE G1 certification last?
ASE G1 certification is valid for five years. A recertification exam is required to renew before the expiration date.
How does the G1 compare to the full ASE A-Series?
The G1 is an entry-level credential focused on maintenance and light repair, while the A-Series tests cover advanced diagnostics, electrical systems, engine performance, and more complex repairs. The G1 is often a stepping stone toward pursuing the full A-Series suite.
