Program Overview

The Diesel Applied Technology curriculum offers an opportunity to receive knowledge and develop skills necessary to function as a diesel service technician and mechanic. The curriculum is designed to give a practical approach, under job shop performance conditions, to the study of diesel mechanics.

Diesel service technicians and mechanics are primarily employed by the truck transportation industry, although some are employed by local governments, mainly to repair school buses, waste removal trucks, and road equipment. Employment of diesel service technicians and mechanics is expected to grow about as fast as the average for all occupations. Additional trucks - and truck repairs - will be needed to keep pace with the increasing volume of freight shipped nationwide.
