- You need 56 of 80 scored items correct (70%) to pass the OR-CCB exam.
- Domain 1, Oregon Const. Contractor Laws and Regulations, carries the most scored items at 18.
- Eight unscored experimental items are mixed in, so every question deserves real attention.
- The exam is open book against the NASCLA Contractors Guide, but tabbing and prep still decide outcomes.
What "Pass Rate" Really Means for OR-CCB Candidates
Anyone researching the OR-CCB Contractor License Exam eventually asks the same question: what percentage of people actually pass? The Oregon Construction Contractors Board and PSI, which administers the exam, do not publish a rolling public pass-rate percentage the way some national certifications do. What is publicly documented - and far more useful to you as a candidate - is the exact scoring structure of the exam itself.
That structure tells a more actionable story than any single pass-rate figure could. The exam is built from 80 scored multiple-choice items plus 8 unscored experimental items, for 88 total questions delivered in 200 minutes (180 minutes for the scored portion, 20 for the experimental set). You need 56 correct scored answers - 70% - to pass. Because you cannot tell scored items apart from experimental ones during the test, the only realistic strategy is to treat all 88 questions with equal seriousness.
The Number That Actually Matters: 56 of 80
Rather than chasing an unofficial pass-rate percentage, focus on the one number the Oregon CCB actually publishes: 56 correct answers out of 80 scored items. That's the passing threshold, and it's fixed - there's no curve, no rounding in your favor, and no partial credit for near-miss answers.
For a full breakdown of how this threshold is calculated and what it means for your margin of error, see the dedicated OR-CCB Passing Score 2026 guide. In short: you can miss up to 24 scored questions and still pass, which gives you more room than many candidates assume - but only if you know where those misses are most likely to occur.
Key Takeaway
Missing 24 scored questions is survivable; missing them disproportionately in one or two high-weight domains, like Oregon Const. Contractor Laws and Regulations or Contracts, is what typically pushes a score below 70%.
How the 80 Scored Items Break Down Across 14 Domains
Because there's no published pass-rate breakdown by topic, the smartest proxy for "where candidates struggle" is item weight. Domains with more scored questions carry more risk if you're weak there, and more opportunity if you're strong. Here's the official distribution:
| Domain | Scored Items |
|---|---|
| 1. Oregon Const. Contractor Laws and Regulations | 18 |
| 5. Contracts | 9 |
| 3. Hiring and Managing Employees | 7 |
| 7. Bidding and Estimating | 6 |
| 6. Oregon Lien Law | 5 |
| 8. Scheduling and Project Management | 5 |
| 2. Choosing Your Business Structure | 4 |
| 9. Oregon Building Codes | 4 |
| 10. Jobsite Safety | 4 |
| 11. Environmental Factors | 4 |
| 12. Building Exterior Shell | 4 |
| 13. Financial Management | 4 |
| 14. Tax Basics | 4 |
| 4. Working with Subcontractors | 2 |
Domain 1 alone accounts for over a fifth of your scored total, and Domain 5 (Contracts) is second by a wide margin. Together with Domain 3, these three domains make up nearly half the exam. For a full walkthrough of what each domain actually tests, see the OR-CCB Exam Domains 2026 complete guide.
Domain 1: Oregon Const. Contractor Laws and Regulations
This is the single largest domain and the most common place for scores to slip if a candidate underestimates it. It covers CCB statutes, licensing rules, and regulatory obligations specific to Oregon.
- Know the licensing categories and what triggers a violation.
- Understand CCB enforcement authority versus other agencies.
- Tab this section of the NASCLA manual first - it will get referenced most often.
Where Candidates Lose Points
Without an official published pass-rate percentage, the best evidence of where candidates struggle comes from the structure of the exam itself and patterns anecdotally reported by RMI candidates and instructors. A few recurring themes show up consistently:
- Treating Domain 1 as "common sense." Oregon-specific statutory details (bonding requirements, license categories, CCB authority) don't always match general contracting intuition.
- Underestimating Contracts (Domain 5). Nine scored items on contract law, required clauses, and dispute language is a lot of room to lose points if this section is skimmed.
- Poor manual organization. The exam is open book, but a NASCLA manual without tabs or a working index costs candidates precious minutes per question across 180 timed minutes.
- Ignoring the low-item domains entirely. Domains like Working with Subcontractors (2 items) or Environmental Factors (4 items) feel skippable, but a handful of easy points left on the table across several small domains adds up fast.

The Open-Book Factor: Helpful, Not a Shortcut
One reason raw pass-rate speculation is misleading is that the OR-CCB exam isn't a closed-book memorization test. It's open book, based directly on the NASCLA Contractors Guide to Business, Law and Project Management, Oregon Construction Contractors, 2nd Edition. You're allowed to highlight, underline, index, and tab the manual, and to bring in handwritten notes prepared before test day. You cannot write in the manual during the exam itself, and loose papers aren't permitted.
This changes what "studying" should actually look like. It's less about memorizing every statute word-for-word and more about knowing exactly where in the manual each domain's answers live, so you can locate them inside your 180 scored minutes. Candidates who treat the open-book allowance as a reason to under-prepare tend to run out of time; candidates who over-index without understanding the material tend to second-guess themselves on Domain 1 and Domain 5 questions that require applied judgment, not just lookup.
Registration, Fees, and What Happens If You Don't Pass
Understanding the logistics around the exam also puts pass-rate anxiety in perspective. The exam fee is $60, and testing is available at PSI test centers or via remote proctoring, so scheduling flexibility isn't the obstacle it is with some other exams. The exam window itself is generous - 200 total minutes for 88 items - which reduces the odds that time pressure alone causes a failing score.
If you do pass, you're not done yet: the CCB license application must be filed within two years of your passing date, and it requires bond and liability-insurance evidence along with a $400 fee for a two-year license. Missing that two-year window means your passing score effectively expires for licensing purposes, so treat exam day as the start of a filing clock, not the finish line.

Building a Study Plan Around Domain Weight
Since there's no published pass-rate curve to reverse-engineer, the most reliable strategy is to let item counts drive your study allocation. Spend the most hours where the most points live, then reserve enough time to shore up every smaller domain so nothing is a total blind spot.
Domain 1 and Domain 5
- Read and tab Oregon Const. Contractor Laws and Regulations and Contracts first - together they're 27 of 80 scored items.
- Build your manual index for these two sections before moving on.
Domain 3, 7, 6, 8
- Hiring and Managing Employees, Bidding and Estimating, Oregon Lien Law, and Scheduling and Project Management cover 23 more scored items.
- Practice the on-screen calculator for bidding math.
The remaining eight domains
- Business Structure, Building Codes, Jobsite Safety, Environmental Factors, Exterior Shell, Financial Management, Tax Basics, and Subcontractors - 30 items combined, at 2 to 4 items each.
- Don't skip Working with Subcontractors just because it's only 2 items; an easy question is still a point.
Full-length practice and manual timing
- Run full 88-item, 200-minute simulations under real time constraints.
- Time how long it takes to find answers in your tabbed manual per domain and tighten your index accordingly.

The RMI Requirement and the NASCLA Exemption
Pass-rate discussions often skip over eligibility, but who is even sitting for this exam matters. To qualify as the Responsible Managing Individual (RMI), a candidate must be at least 18, hold an ownership, officer, partner, or management/supervisory role over construction activity, complete at least 16 hours of approved pre-license training, and pass the Oregon exam.
There's one notable shortcut: applicants who already passed the NASCLA commercial general building examination can skip the 16-hour pre-license course entirely. They still must pass the Oregon laws, rules, and business-practices exam - meaning the Oregon-specific content, especially Domain 1, remains non-negotiable regardless of prior credentials. Full eligibility details are covered in OR-CCB Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
The NASCLA exemption removes a training requirement, not a testing requirement - every RMI candidate still faces the same 80 scored items and 70% threshold.
Once licensed, ongoing continuing education keeps the knowledge current: residential licensees need three hours of CCB laws, regulations, and business practices plus five other approved hours after six years of licensure (13 other hours before six years), while commercial Level 1 ranges from 16 to 80 hours based on key-employee count and Level 2 totals 32 hours, both subject to exemptions. That ongoing requirement is a good reminder that the exam isn't testing trivia - it's testing baseline competence for a career. For context on what that career looks like day to day, see OR-CCB Jobs and OR-CCB Salary Guide 2026.
FAQ
No public rolling pass-rate percentage is published by the CCB or PSI for this exam. The verifiable, official numbers are the scoring structure itself: 80 scored items, 56 correct required, which equals 70%.
You can miss up to 24 of the 80 scored items and still pass, since 56 correct answers meets the 70% threshold. The 8 experimental items are unscored but indistinguishable during the test, so answer everything carefully.
Domain 1, Oregon Const. Contractor Laws and Regulations, carries 18 of 80 scored items - by far the largest share. Contracts (Domain 5) at 9 items is the next highest-weight domain.
Not reliably. The manual helps you verify details, but within 180 scored minutes across 80 questions, an untabbed or unfamiliar manual costs time you likely don't have if you're also unsure of the underlying concepts.
Yes. You must file the CCB license application within two years of passing, along with bond and liability-insurance evidence and a $400 fee for a two-year license.
