- The Prov-administered ME-ME exam fee is $90; the initial master license adds $150 plus a $21 criminal-history report fee.
- Licensing requires a 45-hour NEC course completed within two years of application, on top of 576 hours of approved study.
- Wiring Methods & Materials (24%) and Wiring & Protection (19%) together make up 43 of the 100 exam questions.
- Licenses last two years; renewal costs $150, and each three-year code cycle requires a Board-required 15-hour NEC update.
What the ME-ME Exam Actually Costs
Before you can call yourself a Maine master electrician, you have to clear the state's computer-based exam and pay a specific set of fees along the way. The Maine Electricians' Examining Board, housed inside the Office of Professional and Occupational Regulation, sets the licensing requirements, but the exam itself is delivered through Prov, either at a physical Prov test center or remotely through Examroom.
The exam fee itself is $90. That single payment covers your seat for the 100-question, multiple-choice, open-book exam, which you're given four hours to complete. A passing score requires answering 70% of questions correctly. Once you pass, licensing itself carries its own separate charges - the initial master license costs $150, plus a $21 criminal-history report fee that's processed as part of the application.
Full Cost Breakdown Table
Here's how the mandatory fees line up. Note that this table reflects only the costs specified for the Maine Master Electrician License Exam - not generic "exam cost" figures you might see floating around for other credentials that also use the ME-ME abbreviation.
| Item | Cost | When It's Paid |
|---|---|---|
| ME-ME Exam Fee (Prov) | $90 | At scheduling, after Board approval |
| Initial Master License | $150 | After passing, at application |
| Criminal-History Report | $21 | Bundled with license application |
| License Renewal (every 2 years) | $150 | Each renewal cycle |
| 45-Hour NEC Course | Varies by provider | Within 2 years before application |
| 15-Hour NEC Update | Varies by provider | Each 3-year code cycle |

Costs Before You Even Sit the Exam
The $90 exam fee is the smallest line item in most candidates' total spend. The real cost of becoming a Maine master electrician is the time and coursework required to become eligible in the first place - and that time has a dollar value attached, whether through lost wages, tuition, or both.
Maine recognizes several standard eligibility routes, each paired with 576 hours of approved study:
- 12,000 hours as a licensed helper/apprentice, plus 576 hours of approved study
- 4,000 journeyman hours, plus 576 hours of approved study
- 6,000 journeyman-in-training hours, plus 576 hours of approved study
- Board-accepted comparable qualifications, evaluated case by case
On top of whichever route you qualify under, the Board requires a 45-hour NEC course completed within the two years immediately before you apply. This course isn't optional padding - it's a hard prerequisite, and its cost varies depending on the training provider you choose. Because Board approval has to happen before you're allowed to schedule your test, it pays to get your hours documentation and course completion certificate in order early rather than scrambling near a deadline.
Key Takeaway
Budget for the 45-hour NEC course as a real cost center, not an afterthought - it's required regardless of which hours-based eligibility route you use, and Board approval won't happen without it.
Retake and Rescheduling Costs
If you don't pass on your first attempt, Maine allows electrician retakes within the two-year testing window tied to your eligibility approval. Each retake requires paying the $90 exam fee again, which is exactly why so many candidates treat first-attempt preparation seriously rather than treating the exam as a low-stakes trial run.
Scheduling logistics matter financially, too. You must cancel or reschedule at least three business days before your test date - miss that window and you risk forfeiting your fee entirely and having to pay again to rebook. Whether you test at a physical Prov center or remotely through Examroom, the same rescheduling rule applies.
Understanding exactly how the test is scored also helps you avoid an unnecessary repeat purchase. The ME-ME Passing Score 2026: Exactly What You Need to Pass guide walks through the 70% threshold in detail, and pairing that with a look at How Hard Is the ME-ME Exam? Complete Difficulty Guide 2026 gives a realistic sense of where most first-time candidates lose points.
Renewal and Ongoing Costs
Passing the exam and getting licensed isn't the end of the spending. A Maine master electrician license lasts two years, and renewal costs $150 each cycle. That's a predictable, recurring cost that should factor into any long-term financial planning around the credential.
Beyond the renewal fee itself, license holders must complete a Board-required 15-hour NEC update course for each three-year code cycle. This is separate from license renewal timing and tied instead to the code adoption cycle - so it's worth tracking both dates independently rather than assuming they align.
What You're Paying For: Format and Domains
It helps to know exactly what that $90 buys you on test day. The ME-ME exam is a computer-based, multiple-choice, open-book test: 100 questions, a four-hour time limit, and a 70% passing threshold. "Open-book" here means the approved softcover 2023 NEC - you're allowed to bring the book with tabs, writing, highlighting, and underlining already in it, but you cannot add or insert extra material like sticky notes with formulas or extra reference sheets. A simple four-function calculator is permitted, and you'll need current government-issued photo ID to test.
The 100 questions are distributed across ten domains, and two of them dominate the exam:
Wiring Methods & Materials (24%)
The single largest domain on the exam. Candidates need fluency with conductor types, raceway and cable systems, boxes and fittings, and installation methods as codified in the NEC.
- Expect the highest raw question count of any domain - treat it as your top study priority
Wiring & Protection (19%)
Covers overcurrent protection, grounding and bonding, and circuit protection principles. Combined with Wiring Methods & Materials, these two domains account for 43 of the 100 questions.
- Nearly half the exam sits in just these two domains - study time should reflect that weighting
General Electrical Knowledge (15%) & Equipment for General Use (15%)
Two mid-weight domains covering foundational electrical theory and the equipment rules that apply broadly across installation types.
- Together with the two domains above, these four areas account for 73% of the exam
The remaining six domains - Communication Systems, Service Feeders and Branch Circuits, Motors & Controls, Special Conditions, Special Equipment, and Special Occupancies - carry smaller individual weights (2% to 7% each) but still contribute real points. For a complete breakdown of every domain and how to sequence your review, see the ME-ME Exam Domains 2026: Complete Guide to All 10 Content Areas guide.
Fitting Costs Into Your Study Timeline
Because every retake costs another $90 and reschedules require three business days' notice, it's worth pacing your preparation so you only pay the exam fee once. A weighting-aware timeline helps you avoid wasting study hours - and money - on low-yield domains while under-preparing for the ones that carry the most questions.
Wiring Methods & Materials + Wiring & Protection
- These two domains alone cover 43 of 100 questions - start here
- Work through NEC sections tied to conductor types, raceways, grounding, and overcurrent protection
General Electrical Knowledge + Equipment for General Use
- Each is worth 15% - reinforce foundational theory and general equipment rules
- Practice open-book navigation using your tabbed softcover 2023 NEC, since it's what you'll rely on during the real exam
Remaining Six Domains
- Special Equipment (7%), Special Occupancies (6%), Service Feeders and Branch Circuits (4%), Motors & Controls (4%), Special Conditions (4%), Communication Systems (2%)
- Lower weight, but still 27 combined questions - don't skip them entirely
Simulated Timing + Book Prep
- Practice full 100-question sets under the four-hour limit
- Confirm your NEC book has only allowed tabs, writing, and highlighting - no inserted material
For a structured, day-by-day version of this plan, the ME-ME Study Guide 2026: How to Pass on Your First Attempt goes deeper into how to convert this weighting into a full preparation schedule. Running timed practice sets on our practice test platform is one of the more efficient ways to confirm your pacing before committing to a $90 exam slot.
Is the Investment Worth It?
Between exam fees, the initial license, the 45-hour NEC course, and recurring renewal and NEC update costs, the total financial commitment to earning and maintaining a Maine master electrician license adds up over time. Whether that investment pays off depends on your career trajectory, the kind of electrical work you plan to take on, and how the credential positions you with employers who specifically require a master-level license.
If you're weighing this against other paths, the Is the ME-ME Certification Worth It?
