Diesel Technology - Certificate of Achievement

The Diesel Technology Certificate Program trains students to repair, maintain and operate medium and heavy-duty trucks. The curriculum features hands-on practice of recommended tasks set by the Automotive Service Excellence (ASE) Education Foundation. The certificate program is designed for students who are already working or want to enter the workforce as soon as possible. The program requirements allow students to graduate faster than those pursuing the A.A.S. degree. The course topics cover eight areas: diesel engines, drive trains, brakes, steering and suspension, electrical and electronics, preventive maintenance, gas engines, and heating and air conditioning. The required courses include Diesel Engine Repair, Suspension and Steering, and Heavy Duty Drives. Students will apply their knowledge in small group exercises led by an ASE-certified instructor in state-of-the-art facilities. They will also gain real-world experience as they complete an internship project their last semester.

The Diesel Technology Program is accredited by the National Automotive Technicians Education Foundation (NATEF).
