Diesel mechanic training in Colorado

10 diesel mechanic programs with costs, results and funding that can make them free

4 schools offer these diesel mechanic programs, and Colorado has approved every one for workforce funding. Each shows its price if you pay yourself and how past students did.

Diesel mechanics inspect and repair buses and trucks and maintain diesel engines of every kind. Community colleges and technical schools offer certificates and degrees in diesel repair, employers may require or prefer certification, and some jobs need a commercial driver's license to test-drive trucks and buses.1 In Colorado, 7 of the 10 programs take students without a high school diploma, and 5 are taught partly or fully online.

How to pay for diesel mechanic training in Colorado

WIOA funding can pay for diesel mechanic training in Colorado

Every program on this page is approved for WIOA funding: public workforce funding under the Workforce Innovation and Opportunity Act. It can pay for training for eligible adults, people who lost their job and young people.2People on public assistance, with a low income or lacking basic skills come first, and veterans have priority.3Your state or local area may limit how much WIOA pays and for how long. If a program costs more, a Pell Grant, a scholarship or severance pay can cover the rest.4

Ask at an American Job Center

Eligibility rules apply, and services vary from state to state. Your local American Job Center can tell you whether you qualify. The Department of Labor's page links to the center finder, or call 1-877-US-2JOBS (1-877-872-5627).5

Financial aid and grants for diesel mechanic training

Most students can get federal student aid for college, career school or trade school. A Federal Pell Grant, unlike a loan, usually doesn't have to be repaid. Ask the school whether its program qualifies.67

GI Bill for diesel mechanic training

Veterans, service members and qualified dependents can use GI Bill benefits for non-college training programs.8

The program list does not show which programs accept these. Ask the school.

Where the Colorado diesel mechanic program numbers come from

Which Colorado diesel mechanic programs are on this list?

These are the diesel mechanic programs Colorado approved for WIOA funding (public workforce funding under the Workforce Innovation and Opportunity Act), as reported to the US Department of Labor for program year 2024 (July 2024 to June 2025). Each state keeps its approved programs on an eligible training provider list (ETPL).9 The list here covers programs approved as of June 30, 2025. Schools that never applied for approval are missing, so this is a part of what Colorado offers.

How Colorado diesel mechanic program prices are reported

The price is tuition and required fees for someone paying without workforce funding, as the school reported it. "Trained with WIOA funding" on a program counts the people whose training there WIOA paid toward through a training account in program year 2024; the file never gives counts under 3, so a program without the line may still take WIOA students. It does not say how much of the price WIOA covered. Prices under $100 are treated as not reported, because the file holds many blanks entered as $0. Check the current price with the school.

What the graduate results of these programs measure

The figures at the top of this page are the middle program among those that report results: half did better, half did worse. Results describe students who left each program in recent years: the share who finished, the share working in the second quarter after leaving, and the middle earnings of those working in that quarter. States report earnings for that one quarter because they take them from the wage reports employers file every three months. The yearly figure here is that quarter times four, rounded to the nearest $100: an estimate, and an early one, since it is measured about half a year after training. The quarter as reported is under "More details" on each program. Results are withheld for small programs, and they describe past students, so they are no guarantee.

Why do some diesel mechanic programs say "Not reported"?

Where a school or the state left a field empty, or the Department of Labor withheld it, the page says "Not reported". Nothing here is estimated to fill a gap.

Why the kind of school is left off each program

The file also records whether a school is public, private or nonprofit, but those entries are wrong too often to print next to a school's name, so this page leaves them out.

How reliable are the Colorado figures?

The US Department of Labor's own results site lists Colorado among the states with "known data quality concerns".10 The figures here are shown as the state reported them; check them with the school before you enroll.
