ND-ELEC-B Pass Rate 2026: What the Data Shows

Understanding "Pass Rate" for the ND-ELEC-B

Candidates searching for an "ND-ELEC-B pass rate" are usually hoping for a single percentage that tells them how hard the exam really is. The North Dakota State Electrical Board (NDSEB) does not publish an aggregate pass-rate figure for the Class B electrician exam, so any number you see attached to this specific credential elsewhere on the internet should be treated with suspicion. What NDSEB does publish, clearly and consistently, is the passing grade: 70%. That single number is the real data point worth building a study plan around, and it is the same threshold referenced throughout our ND-ELEC-B Passing Score guide.

Instead of chasing an unofficial pass-rate statistic, it is more useful to look at the structural signals NDSEB does release: the score bands used for retest waiting periods, the exam's time allocation between closed-book and open-book sections, and the eligibility hurdles a candidate must clear before ever sitting for the test. Together, these paint a far more accurate picture of exam difficulty than a borrowed percentage ever could.

How NDSEB Scores the Exam

The Class B exam is scored on a straightforward pass/fail basis at the 70% mark. There is no partial credit narrative published by the board, and no domain-by-domain minimum score requirement disclosed publicly - you need an overall 70% across the combined closed-book and open-book sections. This is why understanding the weight and content of each domain matters more than memorizing isolated facts.

NDSEB supplies the codebooks, calculators, and pencils used during testing, which tells you something important: this is not an exam where you bring your own annotated references. Whatever tabbing or organizational system you plan to use on the open-book portion needs to be compatible with what the board hands you the day of the test, per the examination invitation instructions.

The Three Domains and Where Candidates Struggle

NDSEB organizes the exam content into three subject areas. Each one draws from a different body of knowledge, and candidates who treat them as interchangeable tend to underperform on at least one section. Our ND-ELEC-B Exam Domains guide breaks each area down question by question; here is the short version.

What Failing Actually Costs You

Because there's no published pass-rate percentage, the closest thing to real performance data NDSEB provides is its retest waiting-period structure. The board tiers consequences by how far below passing a candidate scored, which implicitly tells you how it categorizes failure severity:

This tiering is genuinely useful as a study benchmark. If your practice exam scores are consistently landing in the 60-69 range, you're close and should focus on shoring up whichever domain is weakest rather than restarting your prep. If you're scoring in the 50s or below on practice material, that's a signal to slow down and revisit fundamentals before scheduling, since a low score triggers a mandatory multi-month wait plus a brand-new application and fee.

Eligibility Gates Before You Ever Sit the Exam

A meaningful chunk of "pass rate" conversation is really about who gets to the exam room prepared in the first place. NDSEB's eligibility requirements filter candidates before scoring ever enters the picture, and understanding them is covered in depth in our ND-ELEC-B Requirements guide.

• You need at least 18 months and 3,000 hours of qualifying farmstead or one- and two-family residential wiring performed under a master or Class B electrician.
• Commercial wiring experience does not count toward this requirement, regardless of how extensive it is.
• An approved two-year electrical school can supply up to 1,000 hours of experience credit toward the total.
• If the majority of your practical experience was obtained in North Dakota, you must also satisfy an approved electrical-school, related-training, or apprenticeship-program requirement and provide employer verification.
• You must receive approval before scheduling, and once invited, you must test within six months of that invitation.

This structure means the pool of people sitting the exam has already cleared a substantial experience filter - nobody walks in cold. That context matters when you read anecdotal "pass rate" claims online: they're describing a population of candidates who already met a 3,000-hour, farmstead/residential-specific experience bar, not a general test-taking public.

Exam Format: Closed-Book vs. Open-Book Timing

The exam totals 4 hours 30 minutes, split into two distinct sections with very different rules:

• 1 hour, closed book - no codebook access, typically theory and fundamentals.
• 3 hours 30 minutes, open book - codebook access permitted, covering the bulk of state rules and NEC application questions.

The imbalance in time allocation is itself informative: nearly 78% of your total exam time is spent with reference materials in hand. That doesn't make the open-book section easier - it means the questions assume you'll need to look things up, so navigation speed through the NEC and North Dakota's wiring standards becomes as important as raw knowledge. Our How Hard Is the ND-ELEC-B Exam guide goes deeper into how this timing affects difficulty perception among first-time takers.

Building a Study Plan Around the Score Bands

Rather than a generic multi-week calendar, the most useful approach ties directly to the three domains and the retest score bands above. If you're early in preparation, front-load fundamental electricity and state-specific rules, since those tend to be smaller, more discrete bodies of knowledge than the full NEC. Save the largest block of study time for NEC navigation, since it dominates the 3.5-hour open-book portion.

For a condensed reference during this final phase, our ND-ELEC-B Cheat Sheet consolidates the must-know facts in one page, and our ND-ELEC-B Study Guide lays out a fuller first-attempt strategy. You can also run realistic timed sessions through the practice tests on our main site to get comfortable with the pacing before exam day.

After You Pass: Renewal and Compliance

Passing is not the finish line - it's the start of an annual compliance cycle. Class B licenses expire every year on April 30, and renewal requires eight continuing-education hours, at least four of which must be code hours. Missing this rhythm can put your contracting eligibility at risk even after you've cleared the exam itself. The application fee, initial issuance, and each annual renewal are each set at $40, a detail we unpack fully in our ND-ELEC-B Certification Cost breakdown.

Because the license is contracting-only - covering farmstead wiring or one- and two-family residential wiring in cities of 2,500 population or fewer - it's worth understanding exactly what job opportunities it opens up before you invest in exam prep. That's covered in our ND-ELEC-B Salary Guide and our broader ROI analysis, and you can browse practice scenarios anytime on the main practice test platform.
