10.2 Massachusetts Licensing, Supervision, Practice & Continuing Education

Key Takeaways

  • M.G.L. c. 141 distinguishes Class A Master, Class B Journeyman, Class C Systems Contractor, and Class D Systems Technician licenses; their scopes are not interchangeable.
  • A Massachusetts Journeyman is qualified to perform electrical work as an individual and may be legally hired; the law does not reduce every Class B holder to an employee who can never contract, advertise, or obtain a permit.
  • 237 CMR 18 limits a Journeyman to one apprentice under direct supervision and requires license type and number on covered signs, advertisements, or business communications.
  • Current Journeyman examination eligibility includes 600 hours of approved education, a 15-hour Code Update class, and 8,000 hours over at least four years under a licensed Massachusetts Journeyman, plus the documentation rules of 237 CMR 13.
  • For renewal, 237 CMR 17 requires 21 hours: 15 hours of mandatory code/law/business content through an approved provider and 6 hours of qualifying professional development.

10.2 Massachusetts Licensing, Supervision, Practice & Continuing Education

Quick Answer: A Class B Journeyman Electrician is not merely an employee forbidden to deal with the public. M.G.L. c. 141 and the Board's consumer guidance recognize a Journeyman as qualified to perform electrical work as an individual, and 237 CMR 18 requires a Journeyman who installs electrical work to comply with the permit process. A Master license becomes essential when employing Journeymen or apprentices in the manner defined for a Master or when acting as licensee of record for a business entity.


1. License Classes and Statutory Roles

M.G.L. c. 141, § 1 defines the principal categories:

  • Class A — Master Electrician: a person, firm, or corporation having a regular place of business that, by employment of Journeymen or apprentices, performs electrical work under the statute.
  • Class B — Journeyman Electrician: an individual qualified to perform electrical work.
  • Class C — Systems Contractor: the contracting classification for the limited systems scope defined by law.
  • Class D — Systems Technician: the individual technical classification for that systems scope.

M.G.L. c. 141, § 3 authorizes a Class B holder to engage in the occupation of Journeyman Electrician. The Board's official consumer fact sheet says only a licensed Master or Journeyman can legally be hired for electrical work and describes the Journeyman as working as an individual. Therefore, an exam answer stating that a Journeyman can never contract with a customer, advertise, or file a permit is overbroad.

A business organized as a corporation, LLC, LLP, or other entity has separate licensing and licensee-of-record requirements. The right answer depends on whether the question concerns an individual Journeyman, a Master employing others, or a business entity.

2. Permits and Business Communications

237 CMR 18.01 requires any Master, Journeyman, or Systems Contractor performing electrical installations to comply with the permit process required by M.G.L. c. 143, § 3L. The rule separately says a Systems Technician may not file for permits on the technician's own behalf. That contrast is important: the Board did not state that only a Class A Master can ever file an electrical permit.

Local forms and project facts still matter. The permit applicant must be authorized for the work and the permit must identify the responsible installing entity. A Journeyman cannot use individual Class B status as a way to operate a business entity that legally requires a Master licensee of record or to employ multiple licensees outside the statutory structure.

Under 237 CMR 18.01(2), covered signs, advertisements, or other business communications of a Master, Journeyman, or Systems Contractor must display the license type and license number. This rule regulates Journeyman advertising; it does not prohibit all Journeyman advertising. Board policy distinguishes a basic no-cost telephone-directory listing from a paid or enhanced advertisement.

3. Apprentice Supervision

M.G.L. c. 141, § 8 and 237 CMR 18 limit a Journeyman to one apprentice under direct supervision or employment at a time. A compliant two-apprentice crew therefore needs two appropriately licensed supervising electricians, not one Journeyman nominally checking both crews.

“Direct supervision” should be applied from the actual regulation and work circumstances. An apprentice may not be used as an unsupervised substitute for a licensee. The supervising licensee remains responsible for work performed under that supervision. Do not add unsupported universal statements about a particular number of feet, continuous line of sight, or a rule number different from the current text.

4. Journeyman Eligibility and Application

The current Massachusetts application page lists these core Journeyman requirements:

  • 600 hours of Board-approved education;
  • a 15-hour Code Update class;
  • 8,000 hours of electrical work over at least four years under a licensed Massachusetts Journeyman;
  • submission of the online application and supporting documents to PSI.

237 CMR 13 governs education, experience, equivalency, documentation, and special pathways. It also includes the high-school-diploma or equivalent requirement. Out-of-state, military, vocational-school, and organization-based training credits have detailed limits; candidates should never assume all hours transfer automatically.

Current application and examination charges total $226 for a Journeyman candidate: $60 PSI processing, $80 trade-portion administration, $55 applied-portion administration, and $31 Massachusetts processing. The state page identifies a military-related waiver for the $31 fee. Licensing after passing is a separate fee.

5. Examination Status and Repeat Attempts

Both parts must be passed within the candidate's 12-month approval period. A candidate who passes one part and fails the other can retake the failed part while the approval and passed result remain valid.

Current 237 CMR 14 adds education consequences to repeated failure. A candidate who fails must wait at least 24 clock hours to reschedule and sit again. After three unsuccessful attempts, the candidate must furnish proof of reviewing and addressing deficiencies with a Board-approved provider; the requirement can instead be met by an examination-preparation course or a Board-approved 15-hour continuing-education course if not previously taken. After six unsuccessful attempts, the candidate must repeat the full initial education applicable to the license. If the examination changes to a later code, regulation, or law after the candidate failed, the required 15-hour code-update education also matters. Read the current regulation and PSI instructions for documentation and scheduling rather than relying on a generic waiting-period rule.

6. Continuing Education for Renewal

237 CMR 17 requires 21 clock hours during the applicable renewal cycle for Master and Journeyman licensees:

  • 15 hours on the current electrical code and related Massachusetts law, regulations, and business subjects, completed through the prescribed approved-provider framework;
  • 6 hours of professional development selected from qualifying subjects such as electrical code, business, law, first aid, safety, and related building-code material.

The six professional-development hours are not accurately described as always requiring a Board-approved provider. The regulation permits the licensee to choose qualifying content under its conditions. Keep completion records as required.

For reinstatement, a licensee lapsed beyond 90 days who had not completed continuing education before expiration must complete the latest approved 15-hour course and a six-hour professional-development course. If the license has been expired for more than three years (one license cycle), the former licensee must pass the Massachusetts examination for that license to reinstate. Apply current Board procedure as well as 237 CMR 17.

8. Exam Decision Pattern

When a licensing question asks who may act:

  1. identify the license class;
  2. distinguish an individual from a business entity;
  3. determine whether the person employs others;
  4. check the work scope;
  5. apply permit, advertising, and supervision rules separately.

This prevents the common error of transferring a business-entity restriction to every individual Journeyman.
