Apprentice – Journeyman – Master

Would you like to become a licensed electrician? According to the Massachusetts State Board of Electrical Examiners, before you take the licensing exam you must complete 8000 hours of employment (approximately 4 years) as an apprentice under the direct supervision of a holder of a MA Class B Journeyman’s license and 600 hours of classroom instruction (8 modules – approximately 75 hours each) in electrical code and theory from an approved school based on the current National Electrical Code. Apprentices will not be given credit for work experience completed 6 years prior to the successful completion date of their Board approved education.

There is no set order for the two requirements listed above. For example, you may start working as an electrical apprentice first, or you may start classes first, or do both concurrently.

Employment is expected to increase by 9% from 2016 – 2026 with a 2018 median annual wage of $55,190 (Bureau of Labor Statistics Employment Projections).

All students must bring a current NFPA 70 National Electrical Code Book to all classes. Approved school by the MA Board of State Examiners of Electricians.
