In Wisconsin, 12 of the 20 programs take students without a high school diploma and 8 ask for a diploma or equivalent.

By kind, the 20 programs here are diesel technician certificate or diploma (10 programs), diesel technology (associate degree, 4 programs), heavy equipment mechanic (4 programs), diesel mechanic with CDL (1 program), and 1 more of one other kind.

Which Wisconsin diesel mechanic programs are on this list?

These are the diesel mechanic programs Wisconsin 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).

How the prices and results of Wisconsin diesel mechanic programs are measured

Prices are tuition and required fees for someone paying without workforce funding, as the school reported them; check the current price with the school. Results describe students who left each program in recent years, so they are no guarantee, and the yearly earnings are the reported quarter times four, an estimate. A program without a "Trained with WIOA funding" line may still take WIOA students. Where a field was left empty or withheld, the page says "Not reported", and "Left out" where a figure was filed but failed one of our checks; nothing is estimated to fill a gap. Where the numbers come from explains each figure in full.
