Certification for heavy equipment mechanics is optional. The National Institute for Automotive Service Excellence (ASE) certifies mechanics. Certification by the ASE is recognized as a standard of achievement. Mechanics may be certified in one or more of six different repair areas. These include brakes, gasoline engines, diesel engines, drive trains, electrical systems, and suspension and steering. For certification in each area, mechanics must:

• pass a written exam, and
• have at least two years of experience.

Completion of an automotive mechanic program may be substituted for up to one year of experience. To retain certification, mechanics must retake the tests at least every five years. For more information about licensing, contact:
