Things to Know

Look for programs that are approved by the National Institute for Automotive Service Excellence (ASE).

The military may also provide training. The armed forces use a large number of vehicles and diesel generators, so they need to train specialists to do the maintenance and repair work.

Most programs require students to purchase their own tools, safety equipment, and work clothes.

As diesel technology continues to advance, you will need to keep your skills up to date. Expect to take classes throughout your career. Your employer may pay for this training.

You can become certified by the National Institute for Automotive Service Excellence (ASE). To become certified, you need two years of work experience and must pass an exam (postsecondary education in this field can substitute for one of those years).
