Generally, trainees or helpers must complete a 6-month probationary period. After successful completion, they work toward becoming fully qualified mechanics within 4 to 5 years. In order to be classified a fully qualified mechanic, union trainees must pass a standard mechanics examination administered by the National Elevator Industry Educational Program. Most States and cities also require elevator constructors to pass a licensing examination. Most trainees or helpers assist experienced elevator installers and repairers.
Beginners carry materials and tools, bolt rails to walls, and assemble elevator cars.
Eventually, they learn to do more difficult tasks, such as wiring, which requires a knowledge of local and national electrical codes. High school courses in electricity, mathematics, and physics provide a useful background. Workers with more formal education generally advance more quickly than their counterparts. Many elevator installers and repairers also receive training from their employers or through manufacturers to become familiar with the company's particular equipment. Retraining is very important to keep abreast of technological developments in elevator repair.
