Each one passed a written test and proved **hands-on experience** before working on your car in Upland. Route 66 Auto Repair in Upland, CA has ASE-certified technicians in the bays. ASE, the National Institute for Automotive Service Excellence, certifies individual technicians, not shops, after they pass a written test in a specific area and show hands-on work experience. That means the certification belongs to the person working on your car. ## What does ASE certification actually mean? [ASE](https://www.ase.com/) is an independent nonprofit that tests automotive professionals. A technician chooses a test area, such as brakes, engine performance, electrical systems or heating and air conditioning, and sits for a proctored exam. Passing the test is not enough on its own: ASE also requires documented work experience before it issues the certification. Certifications expire. To keep one, a technician has to recertify on a schedule set by ASE. So a current certification tells you the person has recently shown they know the subject, not just that they passed something years ago. ## Why does it matter that ASE certifies people, not shops? Because a sign on a building does not fix your car. When a shop says it has ASE-certified technicians, the honest follow-up question is: which technicians, and in which areas? Ask us at the counter and a service writer will tell you. It is a fair question and we would rather you ask it than assume. It also means certification is a floor, not a finish line. The diagnosis still has to be right on your specific vehicle, which is why we pair it with testing, photos and a road test. ## How does certification show up on your repair? - Testing before parts: a scan, a pressure test or a voltage reading, depending on the system, before anything is replaced. - Specs, not guesses: torque values, fluid types and service procedures come from the vehicle's specifications. - Clear notes: what was found, what was measured and what failed goes on the repair order in plain words. - A quality check and road test before you get the call that the car is ready. ## Where do technicians use that training most? In the jobs where guessing costs you money. A [check engine light diagnosis](https://route66autorepairshop.com/engine-services/check-engine-light-diagnostics) can point to a dozen parts; the skill is proving which one. Brake work needs measurements and the right parts for how you drive around Upland and on the freeway. Cooling systems in Inland Empire heat need a pressure test, not just a top-off. See our [brake services](https://route66autorepairshop.com/brake-services) and [cooling system work](https://route66autorepairshop.com/cooling-heating-ac-services) for how that plays out. ## Frequently asked questions ### Are all of your technicians ASE-certified? Our technicians are ASE-certified, and the specific test areas vary by person. Ask a service writer at the counter which certifications apply to the work on your vehicle and we will tell you plainly. ### Does ASE certification mean a repair can't go wrong? No. It shows knowledge and experience, not perfection. That is why we also road-test repairs and put comebacks at the front of the line, with the root cause written on the repair order. ### How can I learn more about ASE? Visit ase.com to read how testing and recertification work and which areas ASE covers. The site explains the program from the certifying body itself, which is better than taking any shop's word for it. --- Call (909) 608-7699 or visit https://route66autorepairshop.com/contact for a written estimate.
