How to become a master mechanic?

To become a master mechanic, you need at least a high school diploma or GED certificate. You can take courses in automotive technology through a vocational school to gain the skills necessary to work in a repair shop. After gaining two or more years of experience and completing training in engine repair and automotive computer systems, you can apply for certification through the National Institute for Automotive Service Excellence (ASE). The examination series needed to achieve master mechanic status includes tests in collision repair and truck equipment. You need to take a recertification exam every five years to maintain your status.
