Eligibility for the Master Electrician (Class A) License

Ana's first question for Frank was the obvious one: was she even eligible yet? She had passed the journeyman exam in May 2024 and received her license that June. She had worked full time for Quabbin since then, running service upgrades in Worcester three-deckers and the electrical side of a dental office build-out in Framingham. In the fall of 2025 she had finished a 150-hour master course at a night school in Worcester. Frank pulled up the Board's regulation on his laptop. "Two things," he said. "Time as a Massachusetts journeyman, and the classroom hours. Let's check both."

This lesson works through the eligibility rules for the master exam, how they connect to the journeyman requirements that came before, what counts and what does not, and how to document it so the application goes through the first time.

The two requirements

The master exam eligibility rule is in 237 CMR 13.01. An applicant must already be a licensed Massachusetts journeyman electrician, and must provide documentary proof, satisfactory to the Board, of two things. The first is at least one year of experience as the holder of a Massachusetts journeyman electrician license, actively engaged in electrical work. The second is completion of 150 clock hours of classroom instruction, without substantial interruption, in the subjects described in 237 CMR 22.02. Both must be satisfied before the Board approves the application.

The statute says the same thing in older words. Section 3 of chapter 141 requires that a master license applicant, or a member of the applying firm or an officer of the applying corporation, has passed the examiners' exam and has held a certificate B license, which is the journeyman license, for at least twelve months. The regulation adds the education requirement and the requirement that the year be spent actively doing electrical work.

The journeyman year

The one-year clock starts when the journeyman license is issued, not when the journeyman exam is passed and not when the apprentice hours were finished. Ana passed her exam in May 2024, but her license was issued on June 14, 2024, so the earliest date she could show a full year as a license holder was June 14, 2025. Time spent as an apprentice does not count toward the master year, however skilled the apprentice was.

The regulation also requires that the applicant be actively engaged in electrical work during that year. A journeyman who holds a license but spends the year selling insurance has the license but not the experience. Common summaries of the Board's rules add that experience limited to fire warning, security or other inherently power-limited systems does not qualify. A journeyman who spends the year installing only access control and cameras will be asked to show more general electrical work.

from datetime import date

def master_ready(license_issued, today, course_hours):
    # Earliest date one full year as a licensed journeyman is complete
    try:
        one_year = license_issued.replace(year=license_issued.year + 1)
    except ValueError:                      # license issued on Feb 29
        one_year = date(license_issued.year + 1, 3, 1)
    year_ok = today >= one_year
    hours_ok = course_hours >= 150
    return one_year, year_ok, hours_ok

for name, issued, hrs in [("Ana", date(2024, 6, 14), 150),
                          ("Devon", date(2025, 9, 2), 150),
                          ("Kim", date(2023, 3, 10), 120)]:
    when, y, h = master_ready(issued, date(2026, 1, 20), hrs)
    print(name, "| one year on", when, "| year ok:", y, "| hours ok:", h)

Ana | one year on 2025-06-14 | year ok: True | hours ok: True
Devon | one year on 2026-09-02 | year ok: False | hours ok: True
Kim | one year on 2024-03-10 | year ok: True | hours ok: False

Ana passes both checks. Devon, who became a journeyman in September 2025, has the course but not the year. Kim has more than enough time as a journeyman but only 120 of the 150 classroom hours, so she needs to finish an approved course before applying.

The 150 classroom hours

The 150 hours must come from instruction approved under 237 CMR 22.00, the Board's rules on required electrical education. Approved master courses are offered by vocational schools, community colleges, union training programs and private schools. A typical course covers the current code in depth, advanced calculations, motors and transformers, special occupancies and the business and law topics on Part II of the exam. The regulation says the hours must be completed without substantial interruption, so a course started in 2019 and finished in 2026 may be questioned.

Continuing education does not count toward the 150 hours. A journeyman who takes the 21-hour renewal course every three years is meeting a different requirement. Seminars from manufacturers, online videos and self-study are useful but are not approved master education unless the provider and course have Board approval for that purpose. Common summaries also say education limited to fire warning, security or power-limited systems does not qualify.

Documenting it

The phrase that matters in the regulation is documentary proof satisfactory to the Board. For the journeyman year, that usually means employer certification of the dates and type of work, with payroll records available if the Board asks. For the education, it means a certificate or transcript from the approved provider showing the course, the hours and the completion date. A journeyman who has changed employers during the year needs a certification from each one. Self-employed journeymen should keep permit records, invoices and inspection sign-offs that show the work they performed in their own name.

Gaps cause delays. The Board may ask questions about months with no documented work, about education taken from a provider whose approval had lapsed, or about experience that looks like it was mostly systems work. It is faster to answer those questions in the application than to answer them in a letter after the application has been set aside.

Background: how the journeyman license is earned

The master path starts with the journeyman license, so it helps to know what that license required. Secondary sources describe the Massachusetts journeyman requirement as about 8,000 hours of supervised work over at least four years, together with 600 hours of classroom instruction, followed by the journeyman exam. Those numbers come from a well-known industry summary rather than the regulation itself, so treat them as background and check 237 CMR before advising an apprentice. The point for a master candidate is that the journeyman license already reflects years of supervised field work. The master requirement adds one more year of active work as a licensed journeyman and a classroom course aimed at the master level.

Ana's own path shows how the pieces stack. She registered as an apprentice in 2018, worked under Frank and other licensed electricians at Quabbin, finished her classroom hours at night, passed the journeyman exam and was issued her journeyman license on June 14, 2024. She was actively working as a journeyman from that day on, so her one-year requirement was met on June 14, 2025. She started the 150-hour master course that summer and finished it in November 2025.

Common eligibility problems

Most eligibility problems are paperwork problems. A candidate counts the year from the date of the journeyman exam instead of the date the license was issued. A candidate who left the trade for part of the year assumes the time still counts, when the rule refers to a year of active engagement in electrical work. A candidate takes a course that was not approved for the master requirement, or takes it so long ago that the Board asks questions. A candidate licensed in another state assumes that a license there satisfies the Massachusetts journeyman requirement without checking whether the Board will accept it. Each of these can delay an application by months.

Secondary sources also mention reciprocity between Massachusetts and New Hampshire for some license classes. Reciprocity agreements change and have conditions, so a candidate with an out-of-state license should ask the Board directly what it will accept before paying for courses or exam fees. Luis, the New Hampshire master who moved to Lowell, learned that the hard way when his first plan assumed his license would simply transfer.

Ana also checked her own records against the Board's before applying. The license lookup showed her journeyman license number, issue date and expiration date, and those matched the employer letter Frank wrote describing her work since June 2024. Her course certificate showed the provider, the 150 hours and the completion date. With all three documents agreeing, the Board had nothing to question, and her application was approved on February 10, 2026, without a single follow-up letter. That is the goal for every candidate: an application so complete that the reviewer has no reason to write back.

The Board is the final word on eligibility, and it is far better to ask before applying than to be surprised after paying.

Before and after the exam

Eligibility is checked when the Board reviews the application, before the applicant is allowed to book the exam. After approval, the candidate has a limited time to pass. The bulletin describes a window of twelve months from the application approval date to pass both parts, and limits on the number of sittings before more education is required. Lesson 3 covers those limits. Meeting the eligibility rules does not license anyone; it only lets them take the exam.

Ana's documents were straightforward: her license card with the issue date, a letter from Frank certifying her employment and duties since June 2024, and the certificate from her night school showing 150 hours of approved master instruction completed in November 2025. Frank told her to scan everything into one file before she started the online application.
