ID-REB Exam Domains 2026: Complete Guide to All 15 Content Areas

How the ID-REB Exam Is Structured

Before you can plan a domain-by-domain study strategy, you need to understand how the Idaho Real Estate Broker Exam is actually built. The exam is administered by Pearson VUE on behalf of the Idaho Real Estate Commission, a division of the Idaho Division of Occupational and Professional Licenses. It is a closed-book, computer-based test taken at a physical Pearson VUE test center - no personal calculator allowed, though an on-screen calculator is provided for the math-heavy sections.

The exam contains 130 scored multiple-choice questions split across two portions within a four-hour window:

• National portion: 80 scored questions plus 5 unscored pretest questions
• State portion: 50 scored questions plus 5-10 unscored pretest questions

Each portion is graded on a scaled score, and you need a 75 on each side independently to pass - not a raw percentage. Break time counts against your four-hour clock, so budgeting time across all 15 domains matters more than it might seem at first glance. For a deeper look at exactly what that scaled score means and how it's calculated, see ID-REB Passing Score 2026: Exactly What You Need to Pass.

The 8 National Content Domains

The national portion of the ID-REB draws on broker-level knowledge that's consistent across most U.S. jurisdictions, but it's tested at a broker level of depth - not the entry-level salesperson depth you may remember from your original licensing exam. Here are all eight national domains you'll be tested on:

For a candidate-friendly breakdown of how to actually prepare for these eight areas, the ID-REB Study Guide 2026: How to Pass on Your First Attempt walks through a full preparation sequence rather than just listing topics.

The 7 Idaho State Content Domains

The state portion is where the ID-REB becomes distinctly Idaho. This is also the portion that trips up out-of-state candidates and even experienced Idaho salespeople who haven't studied broker-level state rules before. Here are the seven state domains, with their official weight:

Why License Law Carries the Most Weight

It's worth pausing on why Domain 11 is weighted at 30% while domains like Duties and Powers of the Commission or Licensing Requirements sit at only 4% each. The exam is designed around the responsibilities a designated broker actually carries once licensed - supervising agents, managing trust funds, and staying compliant with Idaho Real Estate Commission rules. That responsibility profile is reflected directly in the weighting: brokers are expected to know rules and compliance cold, and to understand agency and management duties in near-equal measure.

If you're trying to gauge how difficult this makes the exam overall compared to other credentialing tests, How Hard Is the ID-REB Exam?

Mapping Domains to Question Counts

Weights are only published within the state portion, but you can still estimate roughly how many of the 50 scored state questions each domain represents. At 30%, License Law and Rules accounts for roughly 15 of the 50 scored state questions. Brokerage Representation and Brokerage Management, each at 20%, account for roughly 10 questions apiece. Idaho Principles and Practices (12%) lands around 6 questions, Calculations and Closing Costs (10%) around 5, and the two smallest domains - Duties and Powers of the Commission and Licensing Requirements, each 4% - likely contribute only 2 questions each.

On the national side, weights aren't broken out individually, but Real Estate Contracts and Agency is confirmed as the largest of the eight national domains, spread across the 80 scored national questions. Treat the other seven national domains as roughly evenly weighted unless your study materials tell you otherwise, and don't neglect Real Estate Math Calculations simply because it isn't the largest - a missed math question is just as costly as any other.

Scheduling Your Study Around the 15 Domains

Rather than studying all 15 domains with equal intensity, allocate your time in proportion to both scope and weight. A simple way to do this is to dedicate early weeks to the two largest concentrations of material - national contracts/agency and state license law - then layer in the mid-weight domains, and finish with review and math drills.

This kind of proportional scheduling - spending more calendar time on high-weight, high-scope domains rather than splitting study hours evenly across 15 topics - is the single most ID-REB-specific study tactic available to you.

Registration, Fees, and Timing Mechanics

Understanding the domains only helps if you also understand the mechanics around them. The ID-REB examination fee is $83, paid through Pearson VUE when you schedule your test center appointment. Before you're even eligible to sit for the exam, you must:

• Be at least 18 years old with a high school diploma or equivalent
• Complete at least 90 hours of qualifying broker education within the preceding three years
• Document at least two years of full-time active salesperson experience within the preceding five years
• Meet the current production requirement: 15 completed sales and/or closed listings totaling at least $2 million
• Complete fingerprinting and a background check

Qualified active out-of-state brokers may be eligible for waivers on the national portion, prelicense education, and broker experience, but they must still pass the Idaho state portion. Once you pass a portion, that pass is valid for one year, and both portions plus your license application must be completed within that same one-year window - miss it, and you'll need to retest.
