- The exam has 130 scored questions-80 national, 50 state-in a four-hour window at Pearson VUE.
- State - License Law and Rules of the Idaho Real Estate Commission is 30% of the state portion, the single largest domain.
- You need 90 hours of qualifying broker education plus two years of active salesperson experience within five years.
- Production minimums are 15 completed sales/closed listings totaling at least $2 million before you can even apply.
What the ID-REB Exam Actually Tests
The Idaho Real Estate Broker Exam (ID-REB) is the licensing exam administered on behalf of the Idaho Real Estate Commission, part of the Division of Occupational and Professional Licenses, and delivered through Pearson VUE test centers. It is not a generic national broker exam with a state stamp on it-it's two distinct exams bundled into one appointment, and treating them as identical will hurt you on test day.
If you're still orienting yourself to the credential itself, our overview articles on what ID-REB is and what the acronym stands for are good starting points before you dive into this study guide. For a deeper walk-through of every content area, see our complete guide to all 15 content areas.
Exam Format, Timing, and Fee Mechanics
Candidates sit for a closed-book, computer-based exam at a Pearson VUE center. The mechanics matter as much as the content:
- 130 scored multiple-choice questions - 80 national and 50 state.
- Unscored pretest items - 5 on the national portion and 5-10 on the state portion, mixed in without being flagged.
- Four-hour total time limit covering both portions.
- No personal calculators. An on-screen calculator is provided for the real estate math and closing-cost questions.
- Breaks count against your clock. There's no bonus time for stepping away.
- Exam fee: $83 paid at scheduling.
Because breaks eat into your four hours, plan your pacing before you sit down rather than improvising mid-exam. If you want a granular breakdown of scheduling logistics, registration windows, and deadlines, check testing windows, deadlines, and scheduling. For a full accounting of what the $83 fee does and doesn't cover relative to prelicense education and background checks, see our complete pricing breakdown.
Key Takeaway
Budget your four hours with the split in mind: roughly 60% of your questions are national content and 38% are state content, so allocate time proportionally rather than lingering on early national items.
The 15 Domains: National vs. State Weighting
The exam outline is organized into eight national domains and seven Idaho state domains. The national outline took effect April 1, 2025, and the Idaho state outline has been in effect since July 15, 2017-two different revision cycles, which is a good reminder that state content changes far less frequently than national content.
National Domains (80 Scored Questions)
National - Real Estate Contracts and Agency
This is the largest national domain, so it deserves the most repetition time in your national study block.
- Contract elements, contingencies, and remedies for breach
- Agency relationships and fiduciary duties in a general (non-Idaho-specific) context
Other National Domains
The remaining seven national domains cover real property characteristics and legal descriptions, forms of ownership and title transfer, appraisal and value, general real estate practice, disclosures and environmental issues, financing and settlement, and real estate math calculations.
- Legal descriptions (metes and bounds, government survey) tend to trip up candidates who skip visual practice
- Math calculations rely heavily on proration, loan-to-value, and commission-split problems
State Domains (50 Scored Questions)
State - License Law and Rules of the Idaho Real Estate Commission (30%)
This single domain carries nearly a third of the state portion's weight-more than any other domain on the entire exam. Underinvesting here is the single most common reason candidates fail the state half.
- Idaho Real Estate Commission rule citations and enforcement authority
- Trust account handling and recordkeeping requirements specific to Idaho brokerages
State - Brokerage Representation / Agency Law (20%)
Idaho's agency framework differs from generic agency theory tested on the national side-expect Idaho-specific disclosure timing and representation types.
State - Brokerage Management (20%)
Covers supervisory responsibilities, advertising compliance, and office-level obligations a broker owes the Commission and their agents.
Smaller but Still Scored State Domains
- Duties and Powers of the Real Estate Commission (4%)
- Licensing Requirements (4%)
- Calculations and Closing Costs (10%)
- Idaho Principles and Practices (12%)
Together, License Law and Rules, Brokerage Representation, and Brokerage Management account for 70% of the state portion. That means three of the seven state domains carry the overwhelming majority of your state score. For the exact percentage breakdown and how it maps to question counts, revisit the domain guide, and use our one-page review of must-know facts as a quick recall check once you've studied each area.
| Domain Group | Weight / Volume | Study Priority |
|---|---|---|
| National - Real Estate Contracts and Agency | Largest national domain | High |
| State - License Law and Rules | 30% of state portion | Highest |
| State - Brokerage Representation (Agency Law) | 20% of state portion | High |
| State - Brokerage Management | 20% of state portion | High |
| State - Idaho Principles and Practices | 12% of state portion | Medium |
| State - Calculations and Closing Costs | 10% of state portion | Medium |
| State - Licensing Requirements / Commission Duties | 4% each | Lower, but don't skip |
Eligibility and Registration Mechanics
Before you can even schedule a Pearson VUE appointment, you have to clear Idaho's eligibility gate. This is where the exam differs sharply from entry-level salesperson licensing, and it's a common source of confusion for candidates who assume broker eligibility works the same way.
- Age and education: At least 18 years old with a high school diploma or equivalent.
- Broker prelicense education: A minimum of 90 hours of qualifying broker education completed within the preceding three years.
- Experience: At least two years of full-time active salesperson experience within the preceding five years.
- Production requirement: A current minimum of 15 completed sales and/or closed listings totaling at least $2 million.
- Background check: Fingerprinting and a background check are required before licensure.
Out-of-state brokers who are already active and qualified may receive waivers for the national exam portion, the prelicense education hours, and the broker experience requirement-but they still must pass the Idaho state portion. That waiver pathway is worth understanding fully before you assume you need to start from zero; the full eligibility rundown lives in our requirements and prerequisites guide.
Passing Score: What "Scaled 75" Means
Idaho reports results as a scaled score, not a raw percentage-you need a scaled score of 75 on each portion independently. That's a critical distinction: passing the national portion doesn't offset a weaker state score, and vice versa. Both must independently clear the threshold.
Scaled scoring also means you shouldn't try to reverse-engineer "how many questions I can miss," because the scale accounts for question difficulty rather than a straight percentage-correct calculation. For the full mechanics of how this scoring model works and what it means for your study targets, see our dedicated breakdown of exactly what you need to pass.
Key Takeaway
Study both portions to genuine mastery rather than aiming for a bare minimum-since unscored pretest questions are mixed in undetected, you can't tell in the moment which items count.
A Domain-Weighted Study Timeline
Generic study techniques-spaced repetition, timed drills, active recall-work fine here, but only if you sequence them around the exam's actual weight distribution instead of studying every domain equally. Given that three state domains make up 70% of the state portion, and one national domain is explicitly the largest, your calendar should be lopsided on purpose.
National Foundations
- Real Estate Contracts and Agency (largest national domain) - build this first since it anchors later math and disclosure topics
- Real Property Characteristics and Legal Descriptions
National Depth
- Forms of Ownership, Transfer, and Recording of Title
- Financing and Settlement, plus Real Estate Math Calculations using the on-screen calculator format
Idaho's Heaviest Domain
- State - License Law and Rules of the Idaho Real Estate Commission (30% of the state portion) - dedicate the most hours of any single week here
- State - Duties and Powers of the Real Estate Commission
Brokerage-Level Content
- State - Brokerage Representation (Agency Law)
- State - Brokerage Management
- State - Idaho Principles and Practices and Calculations and Closing Costs
Full-Length Review
- Timed practice sessions on our practice test platform simulating the four-hour, two-portion format
- Targeted review of weak domains flagged by practice results
Running full-length timed sets on a realistic practice test environment before your appointment is the closest you can get to rehearsing the actual break-time and pacing constraints of the real exam. If you're still deciding how much runway to give yourself, our guide on exam difficulty and the data-driven look at what the pass-rate data shows can help you calibrate realistically.
Mistakes That Cost Idaho Candidates a Retake
- Studying national content almost exclusively. With 50 scored state questions and a 30% weight on License Law alone, under-preparing the state portion is the most common failure point.
- Bringing exam-day habits from other calculators. Personal calculators aren't allowed-practice exclusively with an on-screen calculator interface beforehand.
- Ignoring the one-year validity window. Passing one portion and waiting too long to schedule the other can force a retake of content you already mastered.
- Treating pretest questions as scored feedback. Since 5 national and 5-10 state pretest items are unscored and unmarked, don't let one confusing question shake your confidence on the rest.
- Skipping the production-requirement paperwork. Verifying 15 completed sales/listings and $2 million in production takes time-start gathering documentation early, not the week before you want to test.
Once you're licensed, remember that renewal isn't a one-time event either: active licenses renew every two years and require two Idaho Core courses plus 12 elective hours.

Frequently Asked Questions
There are 130 scored questions-80 national and 50 state-plus a handful of unscored pretest items on each portion, all within a four-hour testing window at a Pearson VUE center.
No, but a passed portion is only valid for one year, and both portions plus your license application must be completed within that same one-year period.
State - License Law and Rules of the Idaho Real Estate Commission carries 30% of the state portion, the highest weight of any single domain, making it the top priority for concentrated review.
Qualified active out-of-state brokers may receive waivers for the national exam portion, prelicense education, and broker experience, but they must still pass the Idaho state portion.
Idaho requires a scaled score of 75 on each portion independently rather than a raw percentage, so both the national and state portions must each clear that threshold on their own.
