Education: An increasing number of employers look for workers with postsecondary training in diesel engine repair. Many community colleges and trade and vocational schools offer certificate or degree programs in diesel engine repair. Programs mix classroom instruction with hands-on training, including the basics of diesel technology, repair techniques and equipment, and practical exercises. Students also learn how to interpret technical manuals and electronic diagnostic reports.</p>

Over the course of their careers, diesel technicians must learn to use new techniques and equipment. Employers often send experienced technicians to special training classes conducted by manufacturers and vendors to learn about the latest diesel technology. </span>

Licenses, Certifications, and Registrations: Certification from the National Institute for Automotive Service Excellence (ASE) is the standard credential for diesel and other automotive service technicians and mechanics. Although not required, this certification demonstrates a diesel technician’s competence and experience to potential employers and clients, and often brings higher pay.</p>

Diesel technicians may be certified in specific repair areas, such as drive trains, electronic systems, or preventative maintenance and inspection. To earn certification, technicians must have 2 years of work experience and pass one or more ASE exams. To remain certified, diesel technicians must pass a recertification exam every 5 years. Many diesel technicians are required to have a commercial driver’s license so they may test-drive buses and large trucks. </span>
