The Full Guide
The electrician licensing exam tests your knowledge of electrical theory, the National Electrical Code (NEC), and safe wiring practices. Depending on your license level, the exam may cover residential wiring, commercial systems, grounding and bonding, load calculations, and code compliance.
Most states require separate exams for different license tiers. Apprentice programs often include a written test at the end of each training year. Journeyman exams focus on the NEC and hands-on trade knowledge needed for unsupervised electrical work. Master electrician exams go deeper into project planning, service sizing, and code interpretation.
