IF YOU LOVE CARS, LIKE WORKING with your hands, and have a knack for solving problems, becoming an automotive technician or mechanic is a great career option. Getting started requires less formal education than most other jobs, yet it has the potential to become a rewarding career. Auto technicians and mechanics keep vehicles on the road by providing routine maintenance and doing repairs to correct problems when they occur. On any given day, they could change oil and rotate tires, install alarms and sat-navs, use diagnostic equipment to identify a faulty component, replace worn brakes, adjust timing, rebuild a transmission, and road-test repaired vehicles.Auto technicians and mechanics both have the mechanical ability to work on vehicles. There is one key difference, however, and that is their technical expertise. Vehicles today are increasingly complex, with computers and electronics integrated into nearly every system. Auto technicians are specifically trained to work with computers and other technical aspects of vehicles. This training is important since computerized diagnostics tools have become standard equipment. Once training is complete, auto technicians are certified and earn the designation of "technician." While mechanics do not have the same formal technical training as technicians, there is often little difference in job duties. There are several ways to learn the necessary skills for this work, from an informal apprenticeship to earning an associate degree at a community college. Programs offered by vocational schools are the most popular. These typically last between six months and a year and offer a certificate upon completion. Though relatively short, these programs are intense and packed with a great deal of knowledge and hands-on experience. Regardless of the type and length of formal training, however, on-the-job training is usually needed after graduation to qualify for the best jobs. Employers also prefer candidates with certification from the National Institute for Automotive Excellence. Certification is available in a number of areas, each focused on a specific automotive system, such as automatic transmissions, engine repair, or heating and air conditioning. Those who achieve certification in core areas can earn Master Technician status.Trained and skilled auto technicians and mechanics enjoy a high level of job security. This has become a high-tech career that is always in demand and cannot be outsourced overseas. The job outl
