If you’re thinking about becoming a mechanic, one of the first questions is how long training will take. The answer depends on the type of mechanic you want to be. Automotive, diesel, aviation, and other specialties each have their own timelines, credentials, and program formats.
Automotive Technology
Certificate and diploma programs in automotive technology typically take 10 months to 1 year for full-time students. Associate degrees usually take 2 years. Many automotive technology schools also offer part-time or evening options that may extend the timeline slightly.
- Certificate/Diploma: 10–12 months
- Associate Degree: 2 years
- Focus Areas: engines, transmissions, brake systems, electrical, diagnostics
Diesel Technology
Diesel programs train you to service and repair heavy trucks, buses, and equipment. These can be completed in as few as 10 months for a certificate, while associate degree programs generally last 18–24 months.
- Certificate/Diploma: 10–15 months
- Associate Degree: 2 years
- Focus Areas: diesel engines, hydraulics, powertrains, electronic systems
Aircraft & Aviation Maintenance
Aviation mechanics must meet FAA standards, so programs are more structured. Training at an aviation mechanic school generally takes 18–24 months for a certificate or associate degree, covering both airframe and powerplant (A&P) systems.
- Certificate: 17–24 months
- Associate Degree: 2 years
- Focus Areas: airframes, powerplants, avionics, FAA regulations
Heavy Equipment Mechanics
Heavy equipment mechanic training usually takes 1–2 years, depending on the program. These mechanics service bulldozers, cranes, loaders, and other construction and agricultural equipment.
- Certificate/Diploma: 1 year
- Associate Degree: 2 years
- Focus Areas: hydraulics, transmissions, electrical systems, diagnostics
Motorcycle & Small Engine Mechanics
Training for motorcycle, ATV, and small engine repair is typically shorter. Many programs can be completed in 6 months to 1 year. These are great entry-level programs for those who want to work with powersports or lawn/garden equipment.
- Certificate/Diploma: 6–12 months
- Associate Degree: 2 years (optional)
- Focus Areas: 2-stroke and 4-stroke engines, electrical, fuel systems, diagnostics
Marine Mechanics
Marine technician programs cover boat engines and outboard systems. Training usually takes 1 year for a diploma or certificate. Advanced programs may run up to 2 years if combined with business or electronics coursework. Read: What does a marine mechanic do?
