Program Information

The trucking industry can be very profitable for those who keep vehicles in tip-top condition. You can learn that trade by enrolling in Iowa Western’s Diesel Mechanics program of study, which stresses over-the-road diesel truck maintenance. In just one year, you can earn a Diploma and join this important career field.

Smaller class sizes allow students one-on-one time with instructors. Rather than starting with automotive classes, you will immediately enroll in diesel classes, where we will use our state-of-the-art facility and high-quality equipment to turn you into a top-notch mechanic.

With paid internships available during the summer months, it’s no wonder that this program results in 100 percent job placement. Among the employers who hire Iowa Western graduates are A&M Greenpower, Caterpillar, Cornhusker International, Omaha Truck Center, Penske, Peterbilt Council Bluffs, Werner Enterprises, and many more. The current market is strong, and demand is high.

Students who complete this diploma will earn credit toward completion of the Diesel Technology, A.A.S. degree.
