Automotive technology is rapidly increasing in sophistication, and most training authorities strongly recommend that persons seeking automotive body repair and related jobs complete a formal training program in automotive body repair or refinishing. Programs are offered in high school or in postsecondary vocational schools and community colleges, but these programs provide only a portion of the training needed to become fully skilled. Most new repairers receive primarily on-the-job training, supplemented with short-term training sessions given by vehicle, parts, and equipment manufacturers, when available. Training is necessary because advances in technology have greatly changed the structure, components, and materials used in automobiles. As a result, proficiency in new repair techniques is necessary. For example, the bodies of automobiles are usually a combination of materials, traditional steel, aluminum, and a growing variety of metal alloys and plastics. Each of these materials or composites requires the use of somewhat different techniques to reshape parts and smooth out dents and small pits.

Fully skilled automotive body repairers must have good reading ability and basic mathematics and computer skills. Restoring unibody automobiles to their original form requires body repairers to follow instructions and diagrams in technical manuals in order to make precise three-dimensional measurements of the position of one body section relative to another. New repairers begin by assisting experienced body repairers in tasks such as removing damaged parts, sanding body panels, and installing repaired parts. Novices learn to remove small dents and to make other minor repairs. They then progress to more difficult tasks, such as straightening body parts and returning them to their correct alignment.

Generally, to become skilled in all aspects of body repair requires 3 to 4 years of on-the-job training. Certification by the National Institute for Automotive Service Excellence (ASE), although voluntary, is the recognized industry credential for automotive body repairers. Repairers may take from one to four ASE Master Collision Repair and Refinish Exams. Repairers who pass at least one exam and have 2 years of hands-on work experience earn ASE certification. The completion of a postsecondary program in automotive body repair may be substituted for 1 year of work experience. Those who pass all four exams become ASE Master Collision Repair and Refinish Technicians. Automotive body repairers must retake the examination at least every 5 years to retain their certification.

While the ASE designations are the most widely recognized, many vehicle manufacturers and paint manufacturers also have product certification programs available for body repairers. Continuing education is required throughout a career in automotive body repair. Automotive parts, body materials, and electronics continue to change and to become more complex and technologically advanced. To keep up with the technological advances, repairers must continue to gain new skills, read technical manuals, and attend seminars and classes. Many companies within the automotive body repair industry provide ongoing training for workers. As beginners increase their skills, learn new techniques, and complete work more rapidly, their pay increases. An experienced automotive body repairer with managerial ability may advance to shop supervisor. Some workers even open their own body repair shops. Others become automobile damage appraisers for insurance companies.
