What the Massachusetts Master Electrician License Actually Opens Up
Job seekers often ask what a "master electrician job" even means in Massachusetts, because the license itself doesn't put you on a ladder wiring a panel - it changes what kind of business you're legally allowed to run. In Massachusetts, a Class A master electrician license is the credential that authorizes operating an electrical contracting business: pulling permits, bidding jobs, hiring crews, and taking legal responsibility for work performed under your name. A Class B journeyman license, by contrast, is what's required to personally perform hands-on electrical work as an employee.
That distinction matters for anyone researching MA-ME jobs. The Massachusetts Master Electrician License Exam (Part 1, the technical exam) plus the separate Business and Law Part II are what stand between a licensed journeyman and business ownership, supervisory authority, or a contractor title on a job site. If you're unclear on what the credential is at a foundational level, What Is MA-ME? and MA-ME Meaning cover the basics before you dive into exam mechanics.
Who Hires Massachusetts Master Electricians
Employers and clients who need a Class A license on file typically fall into a few categories:
- Electrical contracting firms that need a licensed master to pull permits and supervise crews across residential, commercial, and industrial jobs.
- General contractors and construction firms that require a master electrician of record for larger commercial or multi-family projects.
- Facilities and property management companies overseeing ongoing electrical maintenance, upgrades, and code compliance across a portfolio of buildings.
- Specialty installers in growing areas like photovoltaic systems and energy storage, where a master's oversight is often required for permitting and inspection sign-off.
- Solo contractors who complete their journeyman years, pass both exam parts, and open their own shop rather than working under someone else's license.
Whatever direction you're aiming for, the entry point is the same: passing the Massachusetts Master Electrician License Exam Part 1 and the Business and Law Part II. If you're still weighing whether the investment of time and fees is worth it relative to staying a journeyman, Is the MA-ME Certification Worth It? Complete ROI Analysis 2026 and MA-ME Salary Guide 2026: Complete Earnings Analysis dig into that decision in more depth.
The Exam Standing Between You and These Jobs
The technical exam, Part 1, is administered by PSI and consists of 90 questions with a 4-hour limit. You need 70% correct - 63 of 90 - to pass. It's computer-based and open-book at approved Massachusetts testing centers, which means you're allowed reference material during the exam, but not just any material: Ugly's Electrical References and the American Electricians' Handbook are explicitly prohibited, and only a silent, nonprinting, nonprogramming battery-operated calculator is permitted.
Separately, the Business and Law Part II covers 50 questions with a 2-hour limit, also requiring 70% (35 correct) to pass. Both parts must be passed within 12 months after your application is approved - miss that window and you're looking at reapplying. For a full breakdown of exactly what "passing" means numerically, see MA-ME Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Treat Part 1 and Part II as two separate hiring gates on the same clock. Passing the technical exam but letting the 12-month window lapse on Business and Law resets your progress toward a Class A job or business launch.
Domains That Show Up Most on the Job Site - and on the Exam
Part 1's 90 questions are distributed unevenly across 14 domains, and that distribution mirrors what actually comes up on Massachusetts job sites. Wiring Methods and Devices is the single largest domain at 15 questions, followed by Services at 11, then Grounding and Bonding and Special Occupancies and Equipment tied at 10 each. If you want the complete question allocation across all 14 areas, MA-ME Exam Domains 2026: Complete Guide to All 14 Content Areas lays it out domain by domain.
Domain 5: Wiring Methods and Devices
The heaviest-weighted domain on Part 1, and arguably the most day-to-day relevant on any job site - conduit and cable systems, box and device installation, and code-compliant terminations.
- Expect the largest single share of questions here: 15 of 90.
Domain 3: Services
Service entrance sizing, equipment, and disconnect requirements are central to almost every new-construction and upgrade job a master electrician signs off on.
- Carries 11 of 90 questions - second-highest weight on the exam.
Domains 4 and 9: Grounding and Bonding; Special Occupancies and Equipment
Grounding and bonding errors are among the most common code violations inspectors flag, and special occupancies cover the higher-risk environments - hazardous locations, health care facilities, and similar spaces - that a master electrician is expected to supervise correctly.
- Each domain carries 10 of 90 questions.
Beyond the heavyweights, don't overlook the lighter domains - Transformers and Alarm Systems each carry only 1 and 2 questions respectively, but a wrong answer there still counts against your 70% threshold. Employers hiring for photovoltaic or energy storage installation work will also expect familiarity with Domains 13 and 14, even though they're lightly weighted on the exam itself, because those specialties are expanding fast in Massachusetts.
Requirements, Fees, and Timeline to Get Licensed
Before you can even schedule the exam, Massachusetts requires you to hold a Massachusetts journeyman electrician license, have at least one year actively engaged in electrical work as a licensed journeyman, and complete 150 hours of approved master-electrician education, along with required code-update and CORI documentation. If you're still confirming you meet these thresholds, MA-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify walks through each one.
Applications go through PSI online. Once approved, the cost structure looks like this:
| Item | Cost |
|---|---|
| PSI processing fee | $75 |
| Technical exam (Part 1) | $80 |
| Business and Law exam (Part II) | $55 |
| State application charge | $66 |
| Initial package total | $276 |
| Initial license issuance | $155 |
| Retake, Part 1 | $80 |
| Retake, Part II | $55 |

Scheduling Your Prep Around a Working Job
Most candidates pursuing MA-ME jobs are already working full-time as journeymen, so prep has to fit around shift schedules rather than assume open days. A domain-weighted approach makes the limited hours count more than generic review.
Heaviest domains first
- Wiring Methods and Devices (15 questions) and Services (11 questions) - the two domains worth the most points
- Cross-reference the NEC and Massachusetts amendments in 527 CMR 12.00 for each topic as you go
Second-tier weight
- Grounding and Bonding and Special Occupancies and Equipment (10 questions each)
- State Specific Electrical Requirements and Overcurrent Protection (4 and 6 questions)
Business and Law Part II
- 50 questions, 2-hour limit, separate 70% threshold - don't let Part 1 prep crowd this out
Timed practice and open-book pacing
- Simulate the 4-hour, open-book, computer-based format at ../ under realistic time pressure
- Confirm which reference material and calculator type are permitted before test day
If you'd rather follow a more detailed week-by-week plan built specifically around the exam's domain weighting, MA-ME Study Guide 2026: How to Pass on Your First Attempt expands on this structure, and How Hard Is the MA-ME Exam? Complete Difficulty Guide 2026 is worth reading if you want a realistic sense of where candidates typically struggle. For a quick reference during final review, MA-ME Cheat Sheet 2026: One-Page Review of Must-Know Facts condenses the numbers covered here into one page.
Life After the License: Renewal and Career Growth
Getting licensed is the entry ticket to Class A work, not the end of the obligation. Massachusetts renewal runs on a three-year cycle ending July 31, costs $117, and requires 21 continuing-education hours - 15 hours of mandatory code, business, law, and related instruction plus 6 hours of professional development. Employers evaluating master electricians for supervisory or ownership roles will expect this to be current and documented.
It's also worth watching code-adoption timing if you're job hunting near a transition period. Massachusetts adopted its 2026 Electrical Code on April 24, 2026, and board minutes from May 18, 2026 anticipated examination changes by November - but code adoption and exam-content updates don't happen on the same day. Always confirm the PSI-tested edition for your specific appointment rather than assuming the newest code is already reflected on test day.
For candidates weighing whether this whole path is worth pursuing versus staying at journeyman level, or comparing it against other credentials in the trade, MA-ME Certification and What Is MA-ME Certification? give a broader view of what the license represents in Massachusetts specifically. And if you want to see how outcomes actually trend for candidates who complete the process, MA-ME Pass Rate 2026: What the Data Shows is the place to look rather than relying on anecdote.
Key Takeaway
A Class A license is a recurring professional obligation, not a one-time badge - plan continuing education into your calendar the same way you planned your original exam prep.
Whether you're aiming to launch your own contracting business, take on a supervisory role with an existing firm, or move into a growing specialty like solar or energy storage installation, the path runs through the same two-part exam described above. Running through timed practice sessions at ../ before your scheduled test date is one of the more reliable ways to confirm you're actually ready for the 4-hour, open-book format rather than guessing based on how comfortable the material feels on paper.
