Diesel Technology Degree

The Diesel Technology program is designed to provide training in the diagnosis, repair, and maintenance of heavy-duty agricultural equipment, over-the-road diesel trucks, and other heavy-duty diesel systems. The Diesel Technology program will provide training in entry-level skills of mechanical, electrical and fuel systems, power trains, brake systems, air conditioning, welding and hydraulics.

Entrance Advising

Due to the highly technical nature of the Diesel program and NIACC’s commitment to giving students the best possible opportunity for success, students will be scheduled for advisement sessions with counselors and program personnel. In these sessions, the student’s career plans, previous background, transcriptions, test scores, life experiences, and motivation will aid in designing a positive educational experience.

Completion of this program prepares graduates for employment in various occupational areas:

    • Construction companies
    • Consumer product dealerships
    • Engine machine shops
    • Farm agricultural repair shops
    • Heavy equipment shops
    • Independent repair shops
