- The NC Licensing Board for General Contractors does not publish an official NCGC-B pass rate figure.
- Passing requires 70% correct on 90 scored questions within 200 minutes.
- 5 to 10 unscored experimental questions are mixed in and don't count against your time or score.
- Your PSI eligibility notice is valid for 120 days and covers one exam appointment, with retesting allowed within the 12-month application period.
Why There's No Published NCGC-B Pass Rate
If you've searched for a specific pass rate percentage for the North Carolina General Contractor License Exam (Building Contractor), you've likely come up empty. The North Carolina Licensing Board for General Contractors, which oversees this credential with computer-based testing administered by PSI, does not release a public pass/fail percentage for the Building Contractor exam. That's a meaningful distinction from how some other licensing programs operate, and it means candidates researching "pass rate" content elsewhere online should be cautious about numbers that aren't sourced to the Board or PSI directly.
What we can do instead is look at the structural facts the Board and PSI do publish - the scoring threshold, question format, retesting policy, and domain weighting - and use those to understand what actually drives a candidate's odds of passing. That's the approach this article takes, and it's the same evidence-based approach used throughout the NCGC-B Study Guide 2026.
What the 70% Threshold Actually Means
The Building Contractor exam requires a 70% score to pass. With 90 scored multiple-choice questions on the exam, that works out to needing roughly 63 correct answers out of 90 - though the Board scores based on percentage, not a fixed raw count, so treat that as an approximation rather than an exact cutoff. For a full breakdown of how the score threshold is calculated and reported, see the dedicated NCGC-B Passing Score 2026 guide.
Two structural details matter here that are easy to overlook:
- The exam is open-book, meaning approved references may be used during testing. PSI allows these references to be permanently tabbed ahead of time, which rewards candidates who prepare their reference materials in advance rather than scrambling to flip through them mid-exam.
- Alongside the 90 scored questions, PSI may include 5 to 10 unscored experimental questions. These look identical to real questions, but neither your answers nor the time you spend on them counts against your scored performance or the clock in a way that affects your outcome - the point is simply that you can't tell which questions are experimental, so every question deserves full attention.
Key Takeaway
Because references can be pre-tabbed, spend prep time organizing your open-book materials by domain, not just reading them once. A well-tabbed reference set can save minutes per question during the 200-minute exam.
Exam Structure That Shapes Outcomes
The mechanics of the exam itself heavily influence how candidates perform, independent of any published statistic. Consider the pacing: 200 minutes for 90 scored questions (plus a handful of unscored ones) gives most candidates over two minutes per question on average - generous by licensing exam standards, but only if you're not stuck re-deriving formulas or hunting through unfamiliar reference material for the first time during the actual test.
Registration mechanics also affect readiness. The exam fee is $79, and eligibility to sit isn't automatic - applicants must be at least 18 years old, demonstrate good moral character and financial responsibility, pay the applicable application fee, consent to a background check if required, and designate a qualifier who passes a Board-approved examination. Once PSI issues your eligibility notice, it's valid for 120 days and permits one examination appointment. If you don't test within that window, or if you need to retest, you'll do so within your 12-month application period. These timelines are covered in more depth in the NCGC-B Exam Dates 2026 guide and the NCGC-B Requirements 2026 overview.
The current PSI candidate bulletin was updated November 19, 2025, so candidates studying from older materials should verify they're working from the latest version before test day.
The Domain Weighting Behind the Numbers
Because there's no published pass rate to analyze, the most useful "data" a candidate actually has is the domain weighting itself - it tells you exactly where the 90 scored questions are concentrated. The full breakdown lives in the NCGC-B Exam Domains 2026 guide, but the distribution below is worth internalizing on its own.
| Domain | Weight |
|---|---|
| Estimating, Plan Reading & General Building Code Requirements | 15.6% (14 questions) |
| Concrete | 14.4% |
| Metals | 13.3% |
| Carpentry | 7.8% |
| Business and Law | 7.8% |
| Site Work | 6.7% |
| Masonry | 6.7% |
| Roofing | 6.7% |
| Sports Fields | 5.6% |
| Safety | 4.4% |
| Associated Trades | 3.3% |
| One Call | 2.2% |
| Erosion and Sedimentation Control | 2.2% |
| Licensing | 2.2% |
| Liens | 1.1% |
Four domains - Estimating/Plan Reading/Code Requirements, Concrete, Metals, and the combined Carpentry/Business & Law tier - account for close to half of the entire scored exam. That concentration means preparation time isn't evenly distributed either. A candidate who is strong on Liens (1.1%) but weak on Estimating (15.6%) faces a much bigger risk than the reverse.
Estimating, Plan Reading & General Building Code Requirements
This is the largest domain on the exam at 14 of 90 questions. Candidates should expect material covering quantity takeoffs, reading construction drawings, and applying general building code requirements to real-world building scenarios.
- Practice reading plan sets, not just memorizing code sections in isolation
- Cross-reference your tabbed materials so code lookups are fast under timed conditions
- Treat this domain as the anchor of your prep schedule given its 15.6% weight
Concrete and Metals
Combined, Concrete (14.4%) and Metals (13.3%) make up nearly a third of the scored exam. These domains reward candidates who understand structural specifications, mix and material properties, and connection details rather than pure memorization.
- Work through calculation-based problems using your approved calculator
- Review both domains together since structural questions often overlap conceptually
Retesting Rules and the 120-Day Eligibility Window
One of the more practical "data points" affecting outcomes is timing. Because a PSI eligibility notice is only valid for 120 days and covers a single exam appointment, candidates who delay scheduling risk losing that window entirely and having to restart part of the eligibility process. Retesting is available, but it happens within your overall 12-month application period - so a failed attempt doesn't reset your clock indefinitely.
This has a direct implication for how seriously to treat your first attempt: since scheduling and eligibility renewal take administrative time, treating the exam as "practice" with the intent to retake it casually isn't a great strategy. Go in prepared to pass the first time, using resources like the NCGC-B Cheat Sheet 2026 for last-mile review of must-know facts across all 15 domains.
Where Candidates Typically Lose Points
Without an official pass rate to point to, the more useful question is qualitative: what actually trips people up on an open-book, 90-question, 70%-threshold exam like this one? A few patterns show up consistently in how the exam is structured:
- Underestimating the smaller domains collectively. One Call, Erosion and Sedimentation Control, Licensing, and Liens each carry small individual weights (1.1%-2.2%), but together they represent nearly 8% of the exam - enough to matter if ignored entirely.
- Treating "open-book" as a substitute for knowledge. Flipping through untabbed references costs time you don't have across 200 minutes and 90 questions. Familiarity still has to come from actual study, not just access to the material.
- Neglecting Business and Law and Licensing content. These domains test the regulatory side of contracting - qualifier responsibilities, financial requirements, and licensing structure - which candidates focused purely on trade knowledge sometimes underweight.
- Poor time allocation across a long exam. Two hundred minutes sounds like a lot until it isn't; getting stuck early on a difficult Concrete or Metals calculation can cascade into rushed answers later in the test.

Building a Study Plan Around the Real Numbers
Rather than a generic weekly template, the most defensible study plan for this exam is one that mirrors the domain weighting directly. Heavier domains get more weeks; lighter ones get focused review sessions rather than full weeks of dedicated study.
Estimating, Plan Reading & Code Requirements
- Work through plan-reading exercises and takeoff practice
- Build and tab your open-book reference set for code lookups
Concrete and Metals
- Drill calculation-based problems using your approved calculator
- Review structural specification questions from both domains together
Carpentry, Business and Law, Site Work
- Cover qualifier and licensing responsibilities under Business and Law
- Review carpentry framing and site work fundamentals
Remaining Domains and Full Review
- Consolidate Masonry, Roofing, Safety, Sports Fields, and the small-weight domains
- Run full-length timed practice sessions to simulate the 200-minute format
This weighted approach is expanded in full in the NCGC-B Study Guide 2026: How to Pass on Your First Attempt, which walks through resource selection and pacing strategy in more detail.
License Tiers and What's Actually at Stake
Passing the exam is only one part of the licensing equation - the license tier you're qualifying for determines what you can legally build. A state general contractor license is required for any project valued at $40,000 or more, and the tier you hold determines the project size ceiling.
| License Tier | Financial Requirement | Project Limit |
|---|---|---|
| Limited | $17,000 working capital or $80,000 net worth | Up to $750,000 |
| Intermediate | $75,000 working capital | Up to $1.5 million |
| Unlimited | $150,000 working capital | No single-project limit |
Licenses renew annually, and the qualifier for Building licenses must complete 8 hours of Board-approved continuing education each year - a 2-hour mandatory course plus 6 elective hours. This ongoing obligation is worth factoring into the overall cost and time commitment of holding the license, which is broken down further in NCGC-B Certification Cost 2026: Complete Pricing Breakdown.
Once licensed, the practical value of the credential shows up in the types of projects and employers open to you - a topic explored further in Is the NCGC-B Certification Worth It?

Frequently Asked Questions
No. There is no publicly released pass rate percentage for this exam. The most reliable indicators of difficulty are the documented facts: 90 scored questions, a 70% passing threshold, and the 200-minute time limit.
You need to score 70% on the 90 scored questions, which is roughly 63 correct answers, though the Board scores by percentage rather than a fixed raw count. See the NCGC-B Passing Score 2026 guide for more detail.
Your eligibility notice permits one examination appointment within that 120-day window. If it lapses, you'll need to work with the Board and PSI on next steps to regain eligibility, and any retesting still falls within your overall 12-month application period.
No, and that's intentional. The exam may include 5 to 10 unscored experimental questions mixed among the 90 scored ones, so candidates should treat every question on the exam as if it counts.
Estimating, Plan Reading and General Building Code Requirements is the largest domain at 15.6% of the exam (14 of 90 questions), followed closely by Concrete at 14.4% and Metals at 13.3%. These three domains are the highest-leverage use of limited study time.
