In addition to the hands-on training provided, the apprentice must attend at least 144 hours of related classroom instruction per year. In the classroom, apprentices learn blueprint reading, electrical theory, electronics, mathematics, electrical code requirements, and safety and first aid practices. They also receive specialized training in welding, and communications and fire alarm systems. Academic and skills tests must be passed before the apprentice can advance through each phase of the program. Upon successful completion of a Registered Apprenticeship, the apprentice receives a Certificate of Completion from the U.S. Department of Labor, a nationally-recognized credential, and journeyperson electrician status.
Most localities require electricians to be licensed.
Although licensing requirements vary from area to area, electricians generally must pass an examination that tests their knowledge of electrical theory, the National Electrical Code, and local electric and building codes. Electricians periodically take courses offered by their employer or union to keep abreast of changes in the National Electrical Code, materials, or methods of installation. Experienced electricians can become supervisors and then superintendents. Many become construction and safety inspectors in government or business. Some electricians earn university degrees and go on to become industrial technicians and electrical engineers.
