How to become a Diesel Mechanic

There are two educational pathways to a career in diesel mechanics. Certificate programs last from six to nine months. Associate degree programs, which incorporate some general education classes, are typically two years in duration.

Students are encouraged to seek out a program which prepares them for the exams administered by the National Institute for Automotive Service Excellence (ASE). The ASE certification exams related to diesel mechanics cover light vehicle diesel engines, diesel engines (transit bus), electronic diesel engine diagnosis specialist, diesel engines (school bus), and diesel engines (medium-heavy truck). Licensing and certification requirements for diesel mechanics vary from state to state.

The core curriculum of both certificate and associate degree programs is designed around classroom and hands-on learning. Per the sample program summary below, heavy truck maintenance is often the focus of these programs.

• Diesel Mechanics / Heavy Truck Maintenance
