- The exam has 80 scored items plus 8 unscored items, and you need 56 correct (70%) to pass.
- Domain 1 (Oregon Const. Contractor Laws and Regulations) alone accounts for 18 of 80 scored items.
- It's open book from the NASCLA Contractors Guide - Oregon 2nd Edition, but you can't write in it during testing.
- The exam fee is $60, and you have 200 total minutes (180 for scored items, 20 for the unscored set) at a PSI center or via remote proctor.
OR-CCB Exam Overview: Format, Fees, and Logistics
The Oregon CCB Contractor License Exam (OR-CCB) is governed by the Oregon Construction Contractors Board and delivered through PSI testing centers, with a remote-proctor option for candidates who'd rather test from home or the office. The current candidate bulletin has been effective since February 3, 2023, and it's the authoritative source for everything from ID requirements to what you're allowed to bring into the room.
Here's the structure candidates need to internalize before they even open a study guide:
- 80 scored multiple-choice items in 180 minutes
- 8 non-scored (experimental) items in an additional 20 minutes
- 88 total items across 200 total minutes
- Passing score: 70%, meaning 56 of 80 scored items correct
- Exam fee: $60
You won't know which items are the 8 experimental ones, so treat every question on screen as if it counts. The exam is open book, based specifically on the NASCLA Contractors Guide to Business, Law and Project Management, Oregon Construction Contractors, 2nd Edition - not a generic business law text and not a different state's version. If you're still mapping out what the license actually requires beyond the test itself, the OR-CCB Requirements guide covers eligibility in more depth, and our passing score breakdown walks through the scoring math in detail.
The 14 Domains: Where Your Points Actually Come From
The single most important thing you can do before building a study plan is understand how the 80 scored items are distributed. Some candidates spend equal time on every topic in the NASCLA manual, then get blindsided by how heavily one domain is weighted relative to another. A full item-by-item breakdown lives in our OR-CCB Exam Domains guide, but here's the weighting at a glance:
| 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 |
Notice that Domain 1 alone carries more weight than Domains 4, 9, 10, 11, 12, 13, and 14 combined. That's not a coincidence - the Board wants Responsible Managing Individuals who thoroughly understand Oregon-specific licensing law, complaint procedures, and enforcement before they ever touch a jobsite. Contracts (Domain 5) is the second-heaviest domain, which makes sense given how much of a residential or commercial contractor's legal exposure comes down to contract language.
Domain 1: Oregon Const. Contractor Laws and Regulations
This is the backbone of the exam. Expect questions on CCB licensing categories, endorsements, complaint and disciplinary processes, and the statutory duties of a Responsible Managing Individual.
- Know the difference between residential and commercial licensing structures
- Understand what triggers CCB enforcement action
- Be able to locate relevant statute sections quickly in your tabbed manual
Domain 5: Contracts
Nine scored items test your ability to identify required contract disclosures, cancellation rights, and the elements that make a construction contract enforceable in Oregon.
- Memorize which disclosures are mandatory for residential contracts
- Understand change-order documentation requirements
- Know timelines for written notice and cancellation periods
Domain 6: Oregon Lien Law
Five items cover mechanics' liens - who can file, notice requirements, and deadlines. This is dense material, but it's a self-contained section of the manual that rewards focused review.
- Know the notice-of-right-to-lien requirements
- Understand lien filing deadlines relative to project completion
Lower-weighted domains like Working with Subcontractors (2 items) or Environmental Factors (4 items) still deserve a pass through the manual, but don't let them consume study time proportional to Domain 1 or Domain 5. If you're trying to gauge overall difficulty before committing to a study schedule, How Hard Is the OR-CCB Exam? breaks down where most candidates struggle domain by domain.
Working the NASCLA Manual: Open-Book Tactics
The open-book format is a genuine advantage, but only if you've prepared your manual correctly beforehand. The rules are specific: you may highlight, underline, index, and tab the manual - with either removable or permanent tabs - and you may add handwritten notes prepared before test day. What you cannot do is write in the manual during the exam itself, and you cannot bring in loose papers, sticky notes that aren't affixed, or separate reference sheets.
Key Takeaway
Build your tab system around the 14 domains, not the manual's chapter order. Color-code tabs by domain weight - for example, red tabs for Domain 1 and Domain 5 sections - so you spend zero seconds hunting during a 180-minute scored session.
A practical tabbing approach:
- Read through the manual once without tabbing, just to get oriented.
- On a second pass, tab every section that maps to a domain, labeling tabs with domain numbers (1-14).
- Within Domain 1 and Domain 5 - the two heaviest domains - add sub-tabs for licensing categories, disciplinary process, and contract disclosure requirements.
- Write a one-page index by hand (allowed if prepared before testing) listing key page numbers by topic.
Because the exam is timed at roughly 2.25 minutes per scored item on average, flipping through an untabbed 400-plus-page manual page by page is not a viable strategy. Your tabs need to function like a search engine for your own brain.
A Domain-Weighted Study Timeline
Generic study techniques - spaced repetition, timed drills, active recall - work fine here, but only if you apply them against the actual point distribution above. A four-week plan weighted correctly might look like this:
Domain 1 and Domain 5 (27 of 80 scored items)
- Read and tab the Oregon laws/regulations chapter thoroughly
- Read and tab the contracts chapter, focusing on required disclosures
- Build your domain-labeled tab and index system now, while it's fresh
Domains 3, 7, 6, 8 (27 of 80 scored items)
- Hiring and managing employees: worker classification, wage rules
- Bidding and estimating: markup, unit pricing, bid disclosure rules
- Lien law deadlines and scheduling/project management fundamentals
Domains 2, 9, 10, 11, 12, 13, 14 (24 of 80 scored items)
- Business structure options and their liability implications
- Building codes, jobsite safety, exterior shell, and environmental basics
- Financial management and tax basics for contractors
Domain 4 plus full-length review
- Working with subcontractors (only 2 items, but don't skip it)
- Full practice runs under 200-minute timed conditions
- Re-test weak domains identified during practice sessions
For a condensed version of this same logic you can print and keep on your desk during final review, see the OR-CCB Cheat Sheet. And if you want to run full practice sessions that mirror the real 88-item, 200-minute structure, our practice test platform lets you simulate scored and experimental item pacing before test day.
Registration, RMI Eligibility, and Licensing After You Pass
Passing the exam is a milestone, not the finish line. To even sit for the OR-CCB exam as a Responsible Managing Individual, you must be at least 18 years old and be an owner, officer, partner, or an employee who holds management or supervisory authority over construction activity for the applying business. You also generally need to complete at least 16 hours of approved pre-license training before testing.
There's one notable exception: applicants who have already passed the NASCLA commercial general building examination can skip the 16-hour pre-license course, but they still must pass Oregon's own laws, rules, and business-practices exam. That's an important distinction if you're coming to Oregon licensure from out-of-state commercial experience - you're not exempt from Oregon-specific content, only from the training-hour requirement.
Continuing education requirements kick in after you're licensed, and they differ by track:
- Residential CE: three hours of CCB laws, regulations, and business practices plus five other approved hours after six years of licensure, or 13 other approved hours before six years (subject to exemptions).
- Commercial CE, Level 1: ranges from 16 to 80 hours based on the number of key employees.
- Commercial CE, Level 2: totals 32 hours (subject to exemptions).
For a complete walkthrough of every eligibility rule, training hour requirement, and exemption, check the OR-CCB Requirements article. If you're weighing whether the licensing fees, exam cost, and ongoing CE hours are worth it relative to the work you can bid once licensed, Is the OR-CCB Certification Worth It? and the OR-CCB Certification Cost breakdown lay out the full financial picture side by side.
Mistakes That Sink First-Time Candidates
Most repeat test-takers don't fail because the material is unlearnable - they fail because of preventable, structural mistakes:
- Treating the manual as a safety net instead of a tool. If you haven't tabbed and indexed it by domain, "open book" doesn't save you when the clock is running.
- Ignoring the weighting. Spending equal hours on Domain 4 (2 items) and Domain 1 (18 items) is a poor use of limited study time.
- Skipping timed practice. 88 items in 200 minutes feels generous until you're 40 questions in and second-guessing yourself. Simulate the real pacing before test day.
- Assuming personal calculators are allowed. They're not - only the PSI on-screen calculator is permitted, so practice with that interface specifically.
- Missing the two-year application window after passing. A passed exam that isn't converted into a filed application within two years effectively expires.
If you're still building foundational understanding of what this credential actually is and who requires it, our explainer articles - What Is OR-CCB?, OR-CCB Meaning, and What Does OR-CCB Stand For? - are good starting points before you dive into domain-level prep. Once licensed, roles across residential and commercial contracting firms in Oregon typically list active CCB licensure as a hiring prerequisite; see OR-CCB Jobs for how employers frame that requirement.
FAQ
The exam has 80 scored multiple-choice items plus 8 non-scored experimental items, for 88 total. You need 56 correct scored answers - 70% - to pass.
No. The exam is open book only for the NASCLA Contractors Guide to Business, Law and Project Management, Oregon Construction Contractors, 2nd Edition. You may tab, highlight, and add pre-written notes to that manual, but loose papers and outside references are not allowed, and you cannot write in the manual during the test.
You get 180 minutes for the 80 scored items and an additional 20 minutes for the 8 non-scored items, totaling 200 minutes for all 88 questions.
Oregon Const. Contractor Laws and Regulations (Domain 1) carries 18 of 80 scored items, more than any other domain, followed by Contracts (Domain 5) at 9 items. These two domains alone represent roughly a third of your score.
If you've passed the NASCLA commercial general building examination, you can skip the 16-hour pre-license training requirement. You still must pass Oregon's laws, rules, and business-practices exam to become a Responsible Managing Individual.
