ASE Certification Overview & Renewal
What Is ASE?
ASE (National Institute for Automotive Service Excellence) is the organization that provides certification for automotive technicians in the United States. ASE certification is the industry-recognized credential that demonstrates a technician's knowledge and competence across multiple automotive service areas.
ASE offers a series of certification tests organized by specialty area. The main A-series tests cover topics including engine repair, automatic transmission, manual drivetrain, suspension and steering, brakes, electrical/electronic systems, heating and air conditioning, and engine performance.
Certification Renewal
ASE certifications must be renewed every 5 years. Technicians must pass a recertification test in each area to maintain their credentials. This ensures technicians stay current with evolving automotive technology and repair practices.
ASE Renewal App - Continuous Credential Maintenance
ASE now offers the ASE Renewal App as an alternative path for continuous credential maintenance without visiting a testing center. The app works as follows:
- ASE pushes one question per certification area to the technician each month
- Answering correctly earns 1 credit
- Accumulating 8 credits earns a 1-year extension of the certification
- Technicians can maintain certifications indefinitely through the app by staying current on monthly questions
Remote Proctoring for Recertification
Physical Prometric testing centers are no longer the only option for ASE recertification. ASE allows online recertification exams via Prometric ProProctor remote testing from a technician's home or office, with the following limitations:
- Available for most ASE recertification tests
- Exception: L1 and L2 advanced diagnostics tests are not available for remote proctoring and still require an in-person testing center
- Technicians must meet technical requirements (webcam, stable internet, clean room environment)
In-Person Testing (Prometric)
Available for: All ASE tests including L1/L2
Location: Authorized Prometric testing center
Scheduling: Book in advance
Remote Testing (ProProctor)
Available for: Most recertification tests except L1/L2
Location: Home or office
Requirement: Webcam, stable internet, private room
Why ASE Matters
Many employers require or prefer ASE-certified technicians. Certification provides:
- Professional credibility recognized nationwide
- Higher earning potential through demonstrated expertise
- Customer confidence in the quality of service
- Career advancement opportunities in dealerships and independent shops
Exam Tip
When asked "What organization provides certification for automotive technicians in the United States?" - the answer is always ASE (National Institute for Automotive Service Excellence). Do not confuse with OSHA (safety), EPA (environment), or DOT (transportation).
ASE certifications must be renewed every 5 years. The ASE Renewal App allows continuous maintenance by answering one monthly question per certification area - 8 correct answers earns a 1-year extension without visiting a testing center. Most recertification tests can be taken via Prometric ProProctor remote proctoring from home or office, except L1/L2 advanced tests which still require an in-person center.
