- ND-ME stands for the North Dakota Master Electrician License Exam, administered directly by the North Dakota State Electrical Board (NDSEB).
- The exam runs four hours 30 minutes total: a one-hour closed-book section plus a three-hour-30-minute open-book section.
- Passing requires a 70% score across three domains: fundamental electricity, North Dakota laws/rules/wiring standards, and the National Electrical Code.
- Most journeymen qualify with one year and 2,000 hours under a contracting master or master of record, not the full 10,000-hour route.
What ND-ME Stands For
ND-ME stands for the North Dakota Master Electrician License Exam. It is the credentialing exam that North Dakota requires electricians to pass before they can be licensed to work as a master electrician in the state - the license level that sits above journeyman and typically authorizes supervising work, pulling permits, and (with additional business/insurance compliance) operating as a contracting master.
The acronym gets reused across other industries and states, so it's worth being precise: on this site, and in every fact referenced below, ND-ME refers exclusively to the electrical licensing exam overseen by North Dakota's electrical regulator. If you found this page while researching a different "ND-ME," the details here - fees, timing, domains - will not transfer, because they are specific to North Dakota's electrical trade licensure.
Who Administers the Exam
The North Dakota State Electrical Board (NDSEB) directly administers the master electrician examination and approves every applicant before a test date can be reserved. This matters practically: you cannot simply register for a seat the way you might for a generic proctored exam. You apply to the Board first, wait for approval, and only then schedule. If you're unclear on what the Board expects in that application, the ND-ME Requirements 2026 guide walks through eligibility and prerequisites in more depth.
Because NDSEB both writes and grades the exam, its published materials - exam dates page, qualifications page, and application forms - are the only authoritative sources for anything related to ND-ME. Third-party prep content (including this site) should always be checked against current NDSEB guidance for dates and fees before you finalize plans.
Exam Format and Structure
The ND-ME exam is split into two timed sections that combine for four hours and 30 minutes:
- Closed-book section: one hour
- Open-book section: three hours, 30 minutes
A passing score is 70%. The Board supplies code books, calculators, and pencils on exam day - you don't need to bring your own reference materials or calculator, which also means you can't bring in personally tabbed or annotated code books. For a full breakdown of what "passing" actually requires numerically, see the ND-ME Passing Score guide.
Key Takeaway
The closed-book hour tests what you know cold - definitions, formulas, and North Dakota-specific rules you can't look up. The open-book 3.5 hours tests how efficiently you can navigate the NEC under time pressure, not just whether you know the answer exists somewhere in the book.
One scheduling detail candidates often miss: the Board ties exam content to the invitation you receive, not to a fixed calendar date for code adoption. The July 2026 Board newsletter announced that examinations would move to NEC 2026 starting in early fall 2026 - but that switch is separate from the July 1, 2026 construction-code adoption date. Match your study materials to the code edition referenced in your actual exam invitation, not to the adoption date alone. The ND-ME Exam Dates 2026 guide covers this timing distinction in detail.
The Three Exam Domains
NDSEB's published exam scope breaks the ND-ME into three domains. Every question you see on exam day maps back to one of these three areas.
Domain 1: Fundamental Electricity
This covers the core electrical theory a master electrician is expected to know without a reference book open - the material tested in the closed-book hour.
- Ohm's Law and power calculations
- Series and parallel circuit behavior
- Basic motor and transformer principles
Domain 2: Laws, Rules, and Wiring Standards of North Dakota
This domain tests state-specific licensing law and wiring standards that exist outside the national code - material you won't find by studying the NEC alone.
- NDSEB licensing statutes and Board rules
- Contracting master vs. master of record vs. non-contracting master distinctions
- State-specific wiring standards and administrative requirements
Domain 3: National Electrical Code
The largest practical portion of the open-book section, testing your ability to locate and apply NEC rules quickly and accurately.
- Article navigation speed under time pressure
- Load calculations and sizing requirements
- Common code cross-references (grounding, overcurrent protection, branch circuits)
For a deeper dive into how these three domains are weighted and tested, review the ND-ME Exam Domains 2026 guide. If you're still gauging overall difficulty, the How Hard Is the ND-ME Exam guide breaks down where most candidates lose points.
Eligibility Before You Apply
NDSEB documents two experience routes in its application packet:
- Standard journeyman route: at least one year and 2,000 hours working as a licensed journeyman under a contracting master electrician or master of record.
- Full master route: 10,000 hours of overall qualifying experience.
If most of your experience was earned in North Dakota, you'll also need one of: an approved two-year electrical school, 576 hours of approved training, or a recognized professional apprenticeship. Every employer you list must complete a separate experience verification form, signed before a notary - there's no shortcut around this documentation requirement, and incomplete verifications are a common cause of delayed approval.
Fees, Scheduling, and Retakes
The master examination application and re-examination fee is $50. After passing, a separate $50 fee issues your initial master license. For a complete accounting of every cost in the process, see the ND-ME Certification Cost breakdown.
Scheduling has a firm sequence: you must apply and receive Board approval before reserving a test date, and you must test within six months of receiving your examination invitation. Missing that window, cancelling, or no-showing all require submitting a new application and paying the fee again - there's no free reschedule.
| Failed Score Range | Waiting Period Before Retake |
|---|---|
| 60-69% | None |
| 50-59% | Three months |
| 0-49% | Six months |
In every retake scenario, reapplication and another exam fee are required. If you want a realistic sense of how often candidates need a retake and why, the ND-ME Pass Rate data guide is a useful companion read.
After You Pass: Licensing and Renewal
Master licenses expire annually on April 30. Renewal costs $50 and requires eight Board-approved continuing education hours, including at least four code-related hours. Providers must report your completed hours within 15 days, so leaving CE until the last minute leaves little margin if a provider is slow to file.
Passing the exam also doesn't automatically make you a contracting master. North Dakota distinguishes between contracting master, master of record, and non-contracting master statuses - contracting authority specifically requires separate business and insurance compliance on top of the license itself. Understanding which status you're aiming for matters for career planning; the ND-ME Salary Guide and ROI analysis both touch on how license status affects earning potential and job opportunities.
A Domain-Aware Approach to Preparation
Rather than studying generically, sequence your prep around the exam's actual structure. Since Domain 1 (fundamental electricity) is tested closed-book, it rewards memorization and repetition early. Domain 3 (National Electrical Code) is tested open-book, so speed navigating the code - not memorizing article numbers - is the higher-value skill. Domain 2 (North Dakota laws, rules, and wiring standards) is often underweighted by candidates who assume it's "just admin," yet it covers material the NEC doesn't touch at all.
Fundamentals First
- Drill Ohm's Law, power formulas, and circuit theory until closed-book recall is automatic
- Review North Dakota-specific licensing statutes and Board rules (Domain 2)
Code Navigation
- Practice locating NEC articles quickly rather than re-reading passively
- Work load calculation and sizing problems under a timer
Full-Length Simulation
- Take timed practice sessions matching the 1-hour/3.5-hour split
- Review missed questions by domain to target remaining gaps
For a structured week-by-week plan built around this exact split, see the ND-ME Study Guide 2026. And once you're ready to test your recall under realistic time constraints, practice tests on the main site are built around the same three-domain structure NDSEB uses.
Key Takeaway
Don't split study time evenly across all three domains by default - allocate time based on where questions actually live: heavy Domain 3 code-navigation practice, dedicated Domain 2 rule review, and early Domain 1 memorization.
If you're weighing whether pursuing the master license is worth the time and cost relative to staying at journeyman level, the Is the ND-ME Certification Worth It analysis and the ND-ME Jobs overview both give useful context on what the license opens up. And if you're just getting oriented to the credential generally rather than the exam mechanics, What Is ND-ME? and ND-ME Meaning cover the broader picture. For a one-page reference once you're deep into review, bookmark the ND-ME Cheat Sheet, and consider running a few timed sessions on the practice test platform before your invitation date arrives.
