- OR-CCB is the Oregon Construction Contractors Board's licensing exam, administered by PSI.
- The test has 80 scored items plus 8 unscored items, and requires 56 correct answers (70%) to pass.
- It's open book, based specifically on the NASCLA Contractors Guide, Oregon Construction Contractors, 2nd Edition.
- The exam fee is $60; the follow-up CCB license application adds a $400 fee for a two-year license.
What Is An OR-CCB, Exactly?
"OR-CCB" refers to the Oregon Construction Contractors Board licensing exam - the state-mandated test that construction business owners and their designated Responsible Managing Individuals (RMIs) must pass before the CCB will issue a contractor license. It is not a generic industry credential; it is a specific, state-governed exam tied directly to Oregon statute and administered through PSI testing centers and remote proctoring.
The exam is built around a single reference: the NASCLA Contractors Guide to Business, Law and Project Management, Oregon Construction Contractors, 2nd Edition. Every scored question traces back to content in that manual, which makes the OR-CCB exam distinct from broad trade-knowledge tests - it is heavily weighted toward Oregon-specific law, business practice, and contractor obligations rather than hands-on construction technique.
If you're just starting your research, it helps to also read our companion pieces on what OR-CCB stands for and the meaning behind the acronym, since both dig into the regulatory background in more depth.
Who Needs To Pass The OR-CCB Exam
Not every construction worker in Oregon needs this exam - it applies specifically to the person who will serve as the Responsible Managing Individual (RMI) for a contracting business. To qualify as an RMI, a candidate must:
- Be at least 18 years old
- Be an owner, officer, partner, or an employee with management or supervisory authority over the company's construction activity
- Complete at least 16 hours of approved pre-license training (unless exempt)
- Pass the Oregon CCB exam
There's one notable shortcut: applicants who have already passed the NASCLA commercial general building examination can skip the 16-hour pre-license course. They still must sit for and pass the Oregon-specific exam covering laws, rules, and business practices - the state portion isn't waivable. For a full breakdown of every eligibility path, see OR-CCB Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
Passing the NASCLA commercial exam only exempts you from the 16-hour training requirement - you must still pass Oregon's own laws/business-practices exam.
Exam Format, Fees, and Scoring
The OR-CCB exam is computer-based and multiple-choice, delivered at PSI test centers or via remote proctoring for candidates who prefer to test from home or office. Understanding the exact structure matters because time management inside the test is different from most licensing exams you may have encountered.
| Detail | Value |
|---|---|
| Exam fee | $60 |
| Scored items | 80 |
| Time for scored items | 180 minutes |
| Non-scored (experimental) items | 8 |
| Time for non-scored items | 20 minutes |
| Total items / total time | 88 items / 200 minutes |
| Passing score | 70% (56 of 80 scored items correct) |
| Format | Open book, computer-based, multiple-choice |
Because 8 of the 88 items are unscored experimental questions mixed in anonymously, you won't know which questions count and which don't - every item deserves full attention. For the precise math behind the passing threshold and why 56 correct answers is the number to know cold, read OR-CCB Passing Score 2026: Exactly What You Need to Pass.
On calculators: PSI supplies an on-screen calculator built into the testing software, and personal calculators are not permitted. If you're used to bringing your own, practice with an on-screen version beforehand so the interface doesn't slow you down on test day.
The 14 OR-CCB Exam Domains
The exam draws its 80 scored questions from fourteen content domains, and they are not weighted equally. Knowing the item counts per domain lets you prioritize study time realistically instead of spreading effort evenly across topics that carry very different point values.
Domain 1: Oregon Const. Contractor Laws and Regulations (18 items)
This is the single largest domain by a wide margin - nearly a quarter of the scored exam. It covers CCB statutes, licensing rules, and regulatory obligations specific to Oregon contractors.
- Prioritize this domain first in any study plan
Domain 5: Contracts (9 items)
Contract law, required contract provisions, and consumer protection language make this the second-heaviest domain on the exam.
- Know what Oregon law requires in written contracts with homeowners
Domain 3: Hiring and Managing Employees (7 items)
Covers employment classification, supervisory responsibility, and labor obligations tied to running a licensed contracting business.
Domain 7: Bidding and Estimating (6 items)
Focuses on how contractors build accurate bids and estimates within Oregon's regulatory and business framework.
The remaining domains - Choosing Your Business Structure (4), Working with Subcontractors (2), Oregon Lien Law (5), Scheduling and Project Management (5), Oregon Building Codes (4), Jobsite Safety (4), Environmental Factors (4), Building Exterior Shell (4), Financial Management (4), and Tax Basics (4) - round out the remaining scored items. Even the smaller domains matter: with only 80 scored items total, a handful of missed questions across "minor" domains can be the difference between passing and retaking the exam.
For a full walkthrough of every domain with detailed subtopics, our OR-CCB Exam Domains 2026: Complete Guide to All 14 Content Areas covers each one individually. And if you're trying to gauge overall difficulty before committing to a study timeline, How Hard Is the OR-CCB Exam? Complete Difficulty Guide 2026 breaks down what makes this test challenging beyond raw content volume.
Why "Open Book" Doesn't Mean Easy
The OR-CCB exam is open book, which sounds like a relief - but the practical reality trips up a lot of candidates. You're allowed to bring your NASCLA Contractors Guide manual and use it during the test, and you can prepare it extensively beforehand:
- Highlighting and underlining are allowed
- Indexing and tabbing (removable or permanent tabs) are allowed
- Handwritten notes made before the test are allowed
- Writing in the manual during the exam is not allowed
- Loose papers or separate notes brought into the testing room are not allowed
In practice, this means your manual's organization is a study tool in itself. Candidates who build a detailed tabbing system by domain - especially for the heavily-weighted Oregon Const. Contractor Laws and Regulations and Contracts domains - move through the exam far faster than those flipping through an unmarked book under a 180-minute clock.
Key Takeaway
Tab your manual by domain before test day. With 180 minutes for 80 scored questions, you don't have time to search a disorganized book.
What Happens After You Pass
Passing the exam is a milestone, not the finish line. Candidates must file the CCB license application within two years of passing - let that window lapse and you'll need to retest. The application requires:
- Proof of a surety bond
- Evidence of liability insurance
- A $400 fee for a two-year license
Once licensed, ongoing continuing education keeps the license active. For residential licensees, requirements are 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 of licensure (subject to exemptions). Commercial continuing education is more involved: Level 1 ranges from 16 to 80 hours depending on the number of key employees, while Level 2 totals 32 hours, both subject to exemptions.

Building A Domain-Weighted Study Plan
Rather than studying every domain equally, allocate time in proportion to scored item counts. A simple four-week structure built around the actual domain weights looks like this:
Heaviest Domains
- Oregon Const. Contractor Laws and Regulations (18 items)
- Contracts (9 items)
Mid-Weight Domains
- Hiring and Managing Employees (7 items)
- Bidding and Estimating (6 items)
- Oregon Lien Law (5 items)
- Scheduling and Project Management (5 items)
Lighter Domains
- Choosing Your Business Structure (4 items)
- Oregon Building Codes, Jobsite Safety, Environmental Factors, Building Exterior Shell, Financial Management, Tax Basics (4 items each)
- Working with Subcontractors (2 items)
Manual Prep and Timed Practice
- Finalize tabbing and index in your NASCLA manual
- Run full-length timed practice sessions under 180-minute conditions
- Review weak domains identified during practice
This kind of proportional scheduling - spending the most hours where the most points live - is a far better use of prep time than generic study techniques applied evenly across all content. For a day-by-day version of this plan with specific manual sections mapped to each domain, see OR-CCB Study Guide 2026: How to Pass on Your First Attempt. You can also check OR-CCB Exam Dates 2026: Testing Windows, Deadlines & Scheduling to work backward from your target test date, and use a condensed reference like the OR-CCB Cheat Sheet 2026: One-Page Review of Must-Know Facts during your final review week.
Running full-length timed practice questions on our practice test platform before test day is one of the most reliable ways to confirm your pacing works within the 180-minute scored window. Because the real exam mixes 8 unscored items in with the 80 scored ones, practicing under realistic time pressure - rather than untimed review - better simulates what test day actually feels like. Many candidates preparing through OR-CCB Exam Prep also cross-reference domain-specific practice sets with their tabbed manual sections to reinforce both recall and manual navigation speed at the same time.
Frequently Asked Questions
No. Passing the OR-CCB exam is one requirement for licensure. You still need to file a CCB license application with bond and insurance evidence and pay the license fee before you're legally licensed to contract in Oregon.
No. Personal calculators are prohibited. PSI provides an on-screen calculator within the testing software for use during the exam.
You need 56 correct answers out of 80 scored items, which is 70%. That means you can miss up to 24 scored questions and still pass, though you won't know which of the 88 total items are the 8 unscored ones.
If you passed the NASCLA commercial general building examination, you can skip Oregon's 16-hour pre-license training course. You must still pass the Oregon-specific exam covering laws, rules, and business practices.
The CCB license application must be filed within two years after passing the exam. Missing that window generally means you'll need to retake the exam before applying.
