Quick answer: An ASE Certified Master Automobile Technician has passed a series of ASE certification tests across the main areas of automotive service and met ASE’s work-experience requirements. It is a recognized sign of technical knowledge and professional standards.
What is ASE?
ASE is the National Institute for Automotive Service Excellence. It runs certification testing for automotive professionals. Each certification requires qualifying experience and a passed test, and technicians must recertify over time. ASE certification is not a government license, and it does not guarantee the result of any single repair.
Why certification matters, and why it doesn’t replace diagnosis
Many symptoms have more than one possible cause, so technical knowledge matters. A good technician listens, tests the right systems and explains what they found before recommending a repair. That clear explanation is what lets you make an informed decision about safety, cost and next steps.
Meet Rafael Cedillo
Rafael Cedillo owns Cedillo’s Classic & Auto Repair at 1010 W Commonwealth Ave in Fullerton. He is an ASE Certified Master Automobile Technician with more than 25 years of experience. His family-owned shop takes care of everyday cars, pickups and SUVs, as well as classic and vintage vehicles.
Did you know? ASE certification belongs to the individual who earned it, not to every person who works at a shop.
Cedillo’s tip: When you choose a shop, ask what testing they recommend and how they will explain the findings. Clear communication is a big part of peace of mind.
Safety first: Credentials never replace a proper check of new brake, steering, electrical or engine warning signs.
