A high school diploma is suggested for this increasingly complex occupation. High school students may prepare by taking courses in mathematics, metalworking, computer-aided drafting and design, and blueprint reading. Persons interested in this career should be mechanically inclined and able to complete highly accurate work that requires concentration. Postsecondary courses in machine shop are offered at most technology centers in Tennessee.
Military job training consists of between 10 and 12 weeks of classroom instruction, including practice in machine operation. Course content typically includes machine types and uses, machine set up and operation, uses of different metals, and safety procedures. Further training occurs on the job and through advanced courses. The Army and Navy offer certified apprenticeship programs for this occupation.
