How to Get a Diesel Mechanic Apprenticeship (2026)

If you are looking for a formal, state registered diesel mechanic apprenticeship, you will have a hard time finding one. Most people who get paid to learn diesel work do it through a dealer sponsored program or a trainee job, which give you the same deal an apprenticeship does. You earn a paycheck while you learn the trade.

This guide covers where those programs are, what they pay, and how to get into one.

Are There Registered Diesel Mechanic Apprenticeships?

Yes, but very few. Montana is one of the states that publishes active apprenticeships by job, and in 2026 it reported 3 for diesel mechanics, compared with 1,117 for electricians.

That gap tells you to look beyond registered apprenticeships.

What Is the Best Way to Get Paid While You Learn Diesel Work?

For most people, the best path is a dealer sponsored program, where an equipment or truck dealer hires you, sends you to school, and pays you to work in its shop between classes. Caterpillar's ThinkBIG program is the best known example. Here is how it typically works, based on the dealers and colleges that run it:

• Length - About two years, ending with an associate degree in diesel or heavy equipment technology.
• Schedule - You rotate between classes at the college and paid work at the dealership.
• Pay - You earn wages during the work rotations.
• Tuition - Many sponsoring dealers pay tuition or offer reimbursement, and some help you buy tools.
• School weeks - Some dealers do not pay wages during classroom weeks, though benefits may continue.

Lake Area Tech lists about $27,000 for its ThinkBIG program (2024 to 2025) and says its sponsoring dealer's scholarship and paid internship package starts at $30,000, so a sponsored spot can cover most or all of what you would otherwise pay out of pocket.

Dealer programs also lead straight into the highest paying part of the trade. Equipment dealers pay heavy equipment mechanics more than most employers, as the heavy equipment mechanic salary guide shows. You can also browse heavy equipment technician jobs to see which dealers near you are hiring.

How to Get Into a Dealer Sponsored Program

You apply to the dealer first, not the college. Some colleges only admit ThinkBIG students who already have a sponsoring dealer. If you cannot find a sponsor, the diesel mechanic school guide compares what paying your own way costs.

1. Find your local dealers - Look up the Caterpillar dealer and other equipment or truck dealers that cover your area, and check their careers pages for "student technician" or "ThinkBIG" openings.
2. Apply early - Some dealers ask for applications in the spring, roughly January through March, for the next class.
3. Meet the basic requirements - Expect to need a high school diploma or GED, be at least 18 by your first work rotation, and pass the college's placement test.
4. Plan your travel - You will travel between the college and the dealership, so you need reliable transportation.

If a dealer program does not fit, look at diesel technician trainee jobs, which hire people with little or no experience and train them on the job.

How Much Do Diesel Apprentices and Trainees Make?

Expect to start at about half of what a fully trained mechanic earns, then get raises as you learn. According to the Bureau of Labor Statistics, apprentices typically train while "earning about half of what a fully qualified worker makes," with pay increases as they advance.

For diesel work, a fully trained mechanic earns a median of about $61,800 a year, according to BLS May 2025 data, so half of that is about $30,900. Dealer programs often pay more per hour than that during work rotations, which is one more reason they are the better deal when you can get in. Once you finish, the lowest paid 10% of diesel mechanics earn about $44,500, so your pay should jump as soon as you are working full time. The diesel mechanic salary guide shows typical pay in your state.

Can You Get Hired as a Diesel Trainee Without School?

Yes. Truck leasing companies, fleets, and dealers post trainee roles for people with mechanical aptitude and little shop experience, and they train you on the job. Trainee roles usually start with basic work like inspections and preventive maintenance before you move into diagnostics.

Two things make you a stronger trainee candidate. Some fleet trainee roles prefer a CDL, so check whether you need a CDL to be a diesel mechanic for the jobs you want. Once you have about two years of experience, you can sit for ASE certification, which the ASE diesel certification guide walks through.

If you are coming from a different job, build your resume around anything mechanical you have done, from farm equipment to working on your own truck. PopResume is a resume builder you can use for that.
