Diesel mechanic training in Arizona

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

4 schools offer these diesel mechanic programs, and Arizona 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 Under federal rules, anyone paid to handle the refrigerant in a truck's cab air conditioning must be certified by an EPA-approved program.2

In Arizona, 1 of the 6 programs takes students without a high school diploma, 3 ask for a diploma or equivalent and 2 ask for earlier courses first.

By kind, the 6 programs here are diesel technician certificate or diploma (3 programs), diesel technology (associate degree, 2 programs) and medium and heavy truck technician (1 program).

Where the Arizona diesel mechanic program numbers come from

Which Arizona diesel mechanic programs are on this list?

These are the diesel mechanic programs Arizona 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).10 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 Arizona offers.

How the prices and results of Arizona 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.
