About the Massachusetts Master Electrician
Granted by Massachusetts Board of State Examiners of Electricians
Massachusetts Board of State Examiners of Electricians Master (Class A) exam (PSI): two open-book parts, 90 questions in 4 hours and a 50-question Business and Law part in 2 hours, 70% required on each part. Questions follow the 2026 NEC as amended by 527 CMR 12.00, and Massachusetts business, licensing and lien law.
Eligibility Requirements
One year as a licensed Massachusetts journeyman electrician and the 150-hour master curriculum, plus a certificate for the 15-hour code update course.
On the 2026 NEC, with the Massachusetts amendments
Massachusetts adopted the 2026 NEC, amended by 527 CMR 12.00, on April 24, 2026. The Board can add questions on a new code seven months after it takes effect, so 2026 NEC questions can appear from November 24, 2026. Our practice questions are built on the 2026 edition. Where Massachusetts changes a rule, the question follows 527 CMR 12.00, not the national text.

Frequently asked questions
What do I need before I can sit the Master exam?+
One year as a licensed Massachusetts journeyman electrician and the 150-hour master curriculum, plus a certificate for the 15-hour code update course. The Board must approve your application, and the approval lasts 12 months.
What is on the Business and Law part?+
Fifty questions in two hours. Sixteen are on Massachusetts licensing: the Board’s rules (237 CMR) and the electrician licensing law (M.G.L. c. 141). The rest cover estimating, contracts, project management, financial management, tax, labor law, risk management and safety, from the NASCLA contractor’s guide, the state’s wage, workers’ compensation and lien laws, and OSHA’s construction standards.
Is the exam open book? What can I bring?+
Yes. You can bring the NEC, NFPA 72, the Massachusetts amendments (527 CMR 12.00), the Board’s rules (237 CMR) and the General Laws that apply, tabbed or untabbed, with highlighting and handwritten notes in the margins. Formulas may be written on the blank pages of your code book beforehand. Calculators must be silent, battery-operated and non-programmable.
How is the exam scored?+
It is two parts, and each part is scored on its own: you need 70% on each one. If you fail one part, you only retake that part, and you have 12 months from your application approval to pass it. You must wait at least 24 hours before retesting.
What happens if I fail several times?+
After three attempts, the Board requires proof that you reviewed your weak areas with a Board-approved provider, an exam preparation course, or the 15-hour continuing education course. After six attempts you must repeat the full education required for the license.
Where do I take it, and what does it cost?+
PSI gives the exam only at its Massachusetts centers in Auburn, Boston (Charlestown), Fall River, Lawrence and West Springfield. The exam fee is $135: $80 for Part 1 and $55 for Part 2. Application and license fees are paid separately in the state’s eLIPSE portal. To cancel, call PSI at (855) 834-8745 at least two days before your date; a voicemail does not count.
How often do I renew, and how much continuing education is required?+
Licenses expire on July 31 every third year. To renew you need 21 clock hours of continuing education in the three-year period, which includes the 15-hour course on the current Massachusetts Electrical Code.
Does Massachusetts accept a license from another state?+
Massachusetts has no automatic reciprocity list. State law lets the Board license an electrician from another state without the exam when it judges that state’s standards substantially the same, so ask the Board about your license before you apply.
