Description

1. Course Objective: Description: (from catalog)


The Diesel‐Heavy Truck (DHT) diploma program is designed to prepare the student for a career in the diesel medium‐heavy truck technician industry. Classes combine theory with practical application of hands‐on job skills. All courses include the use of hand and specialty tools and emphasize equipment and shop safety procedures. Students should be prepared to sit for the Automotive Service Excellence (ASE) exams and the EPA 609 A/C Technician certification test.


The DHT diploma program is intended for persons with a high school diploma, GED, or recognized equivalent who desire a career inspecting, diagnosing, servicing, and repairing diesel powered medium and heavy trucks and buses.


The DHT diploma graduate may be qualified for entry‐level employment in general diesel medium/heavy truck service positions. As an entry‐level diesel‐heavy truck technician, the DHT graduate will be working with both computerized and mechanical systems.

7. Additional information:





    • Background check requirements for licensing and background restrictions for working in the occupation:




All students applying for admission are required to undergo a background check. The campus uses an unaffiliated service provider to perform these background checks. The campus may deny admission to a prospective student based on the results of his/her background check, or may deny enrollment into certain programs based on those results. The campus may also dismiss an enrolled student as a result of a criminal conviction during the student’s course of study. Certain programs offered by the campus require students to successfully complete externship, practicum or clinical coursework at unaffiliated sites. Before accepting students, certain sites require background checks of their own. A student who cannot be placed at a site for any reason, including a background check result unsatisfactory to that site, may be unable to finish the program’s required coursework and, therefore, may be unable to graduate. Employers in many fields also require pre- employment background checks of their own. Background check results unsatisfactory to employers in a particular field may limit a student’s employment opportunities even if that student has graduated from a program in that field offered by the campus.
