- The ND-ME passing grade is a flat 70% across the entire exam, set by the North Dakota State Electrical Board.
- The exam runs four hours 30 minutes total: a one-hour closed-book section plus a three-hour-30-minute open-book section.
- Scores of 60-69 allow immediate retake; 50-59 require a three-month wait; 0-49 require six months.
- Every retake, cancellation, or no-show requires a new $50 application and fee, so scoring 70% the first time matters financially.
What "Passing" Actually Means on the ND-ME
There's no curve, no scaled score, and no partial-credit adjustment on the North Dakota Master Electrician License Exam. The North Dakota State Electrical Board (NDSEB), which directly administers and grades the exam, sets a single passing grade: 70%. That number applies to the exam as a whole, combining your closed-book and open-book performance into one result that either clears the bar or doesn't.
That simplicity is deceptive. A flat 70% threshold across a four-hour-30-minute exam means there is very little room to write off entire content areas as "not my strength." Weak performance in one domain has to be offset elsewhere, and because the exam blends fundamental theory, state-specific law, and full NEC application, a shaky score in any one area puts real pressure on the other two. If you haven't yet mapped out what each domain actually tests, the ND-ME Exam Domains 2026: Complete Guide to All 3 Content Areas breaks down the scope area by area before you start building a study plan around this passing score.
The Two-Part Exam Format and How Scoring Works
Understanding the passing score requires understanding the structure it's applied to. The ND-ME is split into two timed sections that together total four hours 30 minutes:
- One-hour closed-book section - no code book, no references. This section leans on memorized fundamentals and frequently cited rules you should already know cold.
- Three-hour-30-minute open-book section - code books, calculators, and pencils are supplied directly by the Board, and you'll spend most of this time navigating the National Electrical Code and North Dakota's specific rules to answer application-based questions.
Because the Board supplies the reference materials, part of hitting 70% is simply being fast and accurate at finding the right table, exception, or article under time pressure - a skill that's very different from recalling a fact. Candidates who assume the open-book section is "easier" because references are allowed often underestimate how much time evaporates flipping through an unfamiliar index. If you're unsure how tough this format actually is relative to other trade exams, How Hard Is the ND-ME Exam? Complete Difficulty Guide 2026 covers the practical difficulty factors in more depth.
Key Takeaway
Treat the closed-book hour as a memorization checkpoint and the open-book three-hour-30-minute block as a speed-and-navigation test - both feed into the same 70% total, so neither can be neglected in prep.
The 70% Threshold, Domain by Domain
The Board's exam scope is organized into three published content areas. While the Board doesn't publish a public weighting breakdown for each domain's share of the total score, every question you'll face falls under one of these three areas, and a passing strategy has to account for all of them.
Domain 1: Fundamental Electricity
This covers the theoretical backbone - Ohm's Law relationships, circuit calculations, power formulas, and the physics of how electricity behaves in conductors and components. It's tested heavily in the closed-book hour since it doesn't require a reference to solve.
- Series and parallel circuit math
- Power, voltage, current, and resistance relationships
- Transformer and motor theory basics
Domain 2: Laws, Rules, and Wiring Standards of North Dakota
This is the domain most candidates from out of state, or those who trained mostly in another jurisdiction, underestimate. It covers North Dakota-specific statutes, licensing rules, and wiring standards that sit alongside - and sometimes modify - the national code.
- NDSEB licensing structure: contracting master, master of record, non-contracting master
- State-specific amendments and administrative rules
- Business, insurance, and compliance obligations tied to contracting authority
Domain 3: National Electrical Code
The bulk of the open-book section draws from here. Success depends less on memorizing article numbers and more on being able to locate the correct section fast, under a strict clock, and apply it to a specific scenario.
- Load calculations and service sizing
- Grounding and bonding requirements
- Branch circuits, feeders, and overcurrent protection
For a deeper walkthrough of exactly what falls inside each of these three areas - and how much study time each one realistically deserves - the ND-ME Exam Domains 2026 guide is the natural next stop after this article. Pair that with structured practice on the ND-ME practice test platform so you can see, in real numbers, which of the three domains is dragging your score below 70%.
What Happens If You Fail: Retake Rules
Because the passing score is a hard 70%, it's worth knowing exactly what your score means if you land under it. The Board tiers its waiting periods based on how far below passing you scored - not a flat "wait six months" rule for everyone.
| Score Range | Waiting Period Before Retake | Next Step |
|---|---|---|
| 70% or higher | None - you passed | Pay the $50 fee to receive your initial master license |
| 60% - 69% | No waiting period | Reapply, pay the $50 re-examination fee, schedule again |
| 50% - 59% | Three months | Reapply, pay the $50 re-examination fee, schedule again |
| 0% - 49% | Six months | Reapply, pay the $50 re-examination fee, schedule again |
Notice that a near-miss score in the 60s doesn't buy you a waiting period, but it still costs another $50 application and re-examination fee - the Board doesn't discount retakes. The same is true if you cancel a scheduled exam or simply don't show up: a new application and fee are required to get back in the queue. If you want a full breakdown of every fee tied to the license process, including the separate $50 that issues your initial license once you clear the 70% mark, see the ND-ME Certification Cost 2026: Complete Pricing Breakdown.
Registration, Fees, and Scheduling Mechanics
Passing the exam is only half the equation - getting seated for it correctly matters too, because scheduling mistakes can cost you a testing window. Here's the sequence the Board requires:
- Submit your master examination application along with the $50 application and re-examination fee.
- Wait for Board approval before attempting to reserve a test date - you cannot book a slot on your own timeline before approval comes through.
- Once approved and invited, you must test within six months of the examination invitation.
- After passing, a separate $50 fee issues your initial master license.
Experience documentation has to be airtight before you even reach the scheduling stage. Applicants need at least one year and 2,000 hours working as a licensed journeyman under a contracting master electrician or master of record, and each employer who verifies that experience must complete a separate verification form signed before a notary. If most of your experience was earned in North Dakota, the application also calls for an approved two-year electrical school, 576 hours of approved training, or a recognized professional apprenticeship. Candidates coming from the broader 10,000-hour overall master route face a different documentation path entirely. These requirements are detailed fully in the ND-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify article, and the scheduling windows themselves are laid out in the ND-ME Exam Dates 2026: Testing Windows, Deadlines & Scheduling guide.
Key Takeaway
Approval has to happen before you book a date, and your six-month testing clock starts at invitation - don't let paperwork delays eat into your study runway.
NEC Edition Confusion: The 2026 Newsletter Update
One detail trips up more candidates than it should: which NEC edition governs your exam. The July 2026 Board newsletter announced that updated examinations using NEC 2026 begin in early fall 2026. That's a separate timeline from North Dakota's July 1, 2026 construction-code adoption date - the two are easy to conflate but they are not the same trigger.
The rule that actually matters for your prep is simple: match the examination edition to what's stated on your specific invitation, not to the general construction-code adoption date. If you're approved and invited before the early-fall 2026 switch, you'll likely be tested on the prior edition; if your invitation lands after the switch, expect NEC 2026 references throughout the open-book section. Studying the wrong edition's article numbers and table layouts under a strict clock is one of the most avoidable ways to miss the 70% threshold.
A Short Study Timeline Anchored to the Domains
General study techniques only help if they're pointed at the right material in the right order. Since Domain 1 (fundamental electricity) is tested almost entirely closed-book, it rewards early, repeated recall practice - the kind spaced repetition is built for. Domain 3 (National Electrical Code) rewards timed, open-book navigation drills instead of pure memorization, since you'll have the book in hand. Domain 2 (North Dakota-specific laws and wiring standards) needs dedicated, standalone review because it won't come up naturally while you're drilling national code questions.
Domain 1 Foundations
- Drill Ohm's Law and power-formula problems until they're automatic
- Use short, spaced review sessions rather than one long cram block
Domain 2 State Rules
- Study licensing statuses (contracting master, master of record, non-contracting) and NDSEB administrative rules directly
- Note where state amendments diverge from the base NEC
Domain 3 Code Navigation
- Practice locating load-calculation, grounding, and overcurrent sections against a timer
- Tab your code book for the edition confirmed on your invitation
Full Simulation
- Run a full-length timed practice session on the ND-ME practice test covering all three domains together
- Review the ND-ME Cheat Sheet 2026 for last-pass fact checks

FAQ
You need 70% overall, combining the one-hour closed-book section and the three-hour-30-minute open-book section into a single graded result.
The Board applies one overall passing grade of 70% across the exam. The three scope areas - fundamental electricity, North Dakota laws and wiring standards, and the National Electrical Code - all feed into that single score.
It depends on your score: 60-69% has no waiting period, 50-59% requires a three-month wait, and 0-49% requires six months. A new application and $50 fee are required in every case.
Cancellations and no-shows don't produce a score, but they do require submitting a new application and paying the fee again before you can test.
It changes which code edition your open-book questions reference. The Board's July 2026 newsletter set an early-fall 2026 start for NEC 2026 exams, so confirm the edition listed on your specific invitation rather than assuming based on the construction-code adoption date.
