  • MTECH Program Certificate in Diesel Technology

  • 609 Certification (EPA 609 MVAC)

  • Students are prepared to take ASE certification tests as they complete each course in the program.

What types of diesels do students work on?
Students will work on heavy duty semi truck systems. Students will learn every part of the truck – not just the diesel engine.

How physically difficult is the work?
The work can be difficult, but there are tools that will make make the job easier. Mechanic shops usually require employees and students to lift a minimum of 50lbs.

What tools are required and how should I dress for the class?
A tools list will be given to you on the first day of class. You should be dressed ready to get dirty. Safety toed shoes, safety glasses, and clothes that cover your body well will be important throughout the program. Jewlrey and hair can be a hazard, so it will be impoant to find ways to keep those out of the way.

I already took some classes at my high school, can I skip any of the MTECH classes?
Yes, you can test out of any MTECH diesel course by taking the Professional ASE Certifican Exam that proves your compentency in that area of study.

What if I have my learner’s permit but not my Driver’s License?
A learner permit can be used to register for the course, but you must have a Driver’s License prior to the first day of class. Email of photo of your license or learner’s permit to diesel@mtec.edu.

Is passing the ASE tests required?
No. These tests are challenging. Many experienced technicians do not pass on their first attempt. We use the ASE test as a “high bar to shoot for” rather than a requirement to complete/pass each course. These tests measure mastery rather than proficiency.

What is Hybrid Learning?
This refers to online learning. On the 1st and 3rd Friday Diesel students will have an online assignment that they can complete from home rather than coming to campus.
