An ASE Certified mechanic is a mechanic who has fulfilled the voluntary requirements for certification by the US National Institute for Automotive Service Excellence. Mechanics who have ASE certifications are generally viewed as better candidates for employment by companies that hire these workers, such as auto body shops, car dealers, and bus yards. Certification can also be reassuring for individual consumers who want to ensure that their vehicles receive work from competent, highly professional mechanics.
To become ASE certified, a mechanic has to demonstrate at least two years of work experience and pass at least one specialty test. ASE testing is offered twice a year to candidates who are interested in certifying. When a test-taker passes the test, he or she becomes an ASE Certified mechanic, with a requirement to renew every five years. Mechanics can take tests in a wide variety of systems, such as heating/cooling systems, brakes and suspension, or drive train.
