Associate of Applied Sciences Certificate

Are you interested in preparing for a rewarding career?
Do you want to study in a well-equipped shop?
Do you want to be taught by ASE certified instructors?

We can help you achieve these outcomes by obtaining a Certificate or Associate Degree in Diesel Technology — Heavy Equipment Technology or Medium/Heavy Duty Trucks.

Southeastern's Diesel Technology program is certified by the National Institute for Automotive Service Excellence (ASE) and the National Automotive Technicians Education Foundation (NATEF). As an ASE/NATEF certified program, students leave the program with skills sought after by employers across the nation! The program is also a member of the Association of Diesel Specialists (ADS), an organization "dedicated to the highest level of service on diesel fuel injection and related systems."  All of our instructors are certified by the ADS.

Our Diesel Technology program is in training with Fabick CAT and Cummins Engine Corporation.  The program also has great working relationships with John Deere, Cummins, Fabick CAT, and Pepsi MidAmerica. The instructors work hard to keep these relationships so that our students can experience the best education possible and intern with some of the best companies.  We often get calls from employers wanting our students to apply for employment with their companies.
