What does a diesel mechanic do, and how do you become one?

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

Each figure is the middle program in that state. Yearly earnings are the reported quarter times four, an estimate. Only programs approved for workforce funding are counted; other schools may offer diesel mechanic training too.

Where the diesel mechanic program numbers by state come from

Which diesel mechanic programs are counted?

Programs each state approved for WIOA funding (public workforce funding under the Workforce Innovation and Opportunity Act), from the US Department of Labor's file for program year 2024 (July 2024 to June 2025), covering programs approved as of June 30, 2025. Each state keeps its approved programs on an eligible training provider list (ETPL).7 Schools that never applied for approval are missing.

What the figures for each state mean

Each figure is the middle program among those that report it: half did better, half did worse. Prices are what most programs cost if you pay yourself (the middle half). Earnings are for the second quarter after students left, times four. Where a figure is missing, the table says why: "Not reported", "Left out" or "Not enough data" (what each means).
