- The ID-RES is the Idaho Real Estate Salesperson Exam, governed by the Idaho Real Estate Commission and delivered via Pearson VUE.
- It has 120 scored questions - 80 national, 40 state - plus a handful of unscored pretest items, all within a four-hour window.
- You need a scaled score of 70 on both the national and state portions, not a raw percentage.
- State - License Law and Rules of the Idaho Real Estate Commission carries 40% of the state portion, the heaviest single domain.
What Is the ID-RES, Exactly?
ID-RES stands for the Idaho Real Estate Salesperson Exam - the licensing test every prospective real estate salesperson in Idaho must pass before they can legally represent buyers and sellers in the state. It's governed by the Idaho Real Estate Commission, which sits inside the Division of Occupational and Professional Licenses, and it's administered at physical Pearson VUE test centers rather than online or at home.
This is not a certificate you earn after a weekend seminar. It's a gatekeeping exam tied directly to state law, and passing it is a legal prerequisite for holding an active salesperson license in Idaho. If you've landed here searching "what is a ID-RES," you're most likely a prelicense student trying to understand what stands between you and your license application.
For a broader breakdown of naming and terminology confusion around this credential, see our companion pieces on the ID-RES Meaning and What Does ID-RES Stand For? - both clarify why this acronym gets confused with unrelated credentials outside Idaho.
How the ID-RES Exam Is Structured
The ID-RES is split into two distinct portions that are scored separately, even though they're taken in one sitting:
- National portion: 80 scored questions, plus 5 additional unscored pretest questions mixed in without identification.
- State portion: 40 scored questions, plus 5-10 unscored pretest questions.
That totals 120 scored multiple-choice questions, delivered within a four-hour testing window. The exam is closed-book - no notes, no textbooks, no personal calculator. Pearson VUE provides an on-screen calculator for the math-heavy questions, and it's worth practicing with a similar interface before test day since fumbling with an unfamiliar calculator eats into your limited time. One detail candidates often miss: break time counts against the examination clock, so stepping away to reset mentally isn't "free" time - it's borrowed from your four hours.
Key Takeaway
Because break time is deducted from your four-hour limit, plan your pacing assuming you won't take a break at all, and treat any pause as a deliberate trade-off.
If you want a deeper dive into how difficult this pacing and question load actually feels in practice, our How Hard Is the ID-RES Exam? Complete Difficulty Guide 2026 breaks down the experience question by question.
The 14 Domains That Define the ID-RES
The ID-RES outline splits cleanly into eight national domains and six Idaho-specific state domains. The national outline took effect April 1, 2025, while the state outline has been effective since July 15, 2017 - meaning the state content has had far longer to stabilize, while the national content reflects a more recent revision.
National Domains
- Real Property Characteristics, Legal Descriptions, and Property Use
- Forms of Ownership, Transfer, and Recording of Title
- Property Value and Appraisal
- Real Estate Contracts and Agency
- Real Estate Practice
- Property Disclosures and Environmental Issues
- Financing and Settlement
- Real Estate Math Calculations
Among these, Real Estate Contracts and Agency is the largest national domain - meaning offer/acceptance mechanics, contract elements, and agency relationships deserve outsized attention relative to the other seven.
State Domains and Their Weights
License Law and Rules of the Idaho Real Estate Commission (40%)
This is the single heaviest domain on the entire state portion. Candidates must understand licensing statutes, commission rules, disciplinary authority, and the specific regulatory framework unique to Idaho.
- Know the commission's enforcement powers cold - this domain alone can decide your state score.
Brokerage Representation / Agency Law (25%)
The second-largest state domain, covering how agency relationships are formed, disclosed, and terminated under Idaho-specific rules - distinct from the national agency questions.
Idaho Principles and Practices (15%)
Practical, day-to-day application of Idaho real estate practice standards.
Licensing Requirements (10%)
Covers the pathway into licensure itself - education hours, background checks, and application mechanics.
Duties and Powers of the Real Estate Commission (5%)
A smaller but still testable domain focused on the commission's administrative authority.
Calculations and Closing Costs (5%)
Idaho-specific math applications, separate from the broader national math domain.
Notice the imbalance: two domains - License Law and Rules, plus Brokerage Representation - account for 65% of the entire state portion. That's not a minor detail; it should directly shape how you allocate study hours. For the full breakdown of every domain with sub-topics, see our ID-RES Exam Domains 2026: Complete Guide to All 14 Content Areas.
Scoring: What "Passing" Actually Means
The ID-RES doesn't use a simple raw percentage. Each portion - national and state - is reported as a scaled score, and you need a scaled score of 70 on each portion independently. Passing the national portion with a high score doesn't offset a weak state score; you must clear the threshold on both sides.
| Portion | Scored Questions | Unscored Pretest Questions | Passing Standard |
|---|---|---|---|
| National | 80 | 5 | Scaled score of 70 |
| State | 40 | 5-10 | Scaled score of 70 |
Because scaled scoring adjusts for question difficulty behind the scenes, you can't reliably back into your score from a raw count of correct answers. For the mechanics of how scaled scoring works and what it means for your prep, read ID-RES Passing Score 2026: Exactly What You Need to Pass.
Who Takes the ID-RES, and Why
Anyone pursuing an Idaho real estate salesperson license must pass the ID-RES - there's no way around it, and no employer or brokerage can waive it on your behalf. Idaho brokerages hire licensed salespeople to represent buyers and sellers, and the license itself is the credential that lets you legally earn commission on transactions. Until you hold that license, you cannot practice.
There's one meaningful exception built into the rules: qualified active out-of-state licensees moving to Idaho may receive waivers for the national portion and for prelicense education, but they still must pass the Idaho-specific state portion. If you're relocating with an existing license, this matters a great deal for how you plan your timeline.

Eligibility and Registration Mechanics
Before you can even sit for the ID-RES, you need to satisfy a specific set of prerequisites:
- Be at least 18 years old
- Hold a high school diploma or equivalent
- Complete two 45-hour prelicense education modules within the preceding three years, with full attendance and a passing grade on the course final
- Complete fingerprinting and a background check
Registration is handled through Pearson VUE, and the examination fee is $83. This is a closed-book, computer-based test taken at a physical Pearson VUE test center - there is no remote or at-home option. For a full cost breakdown including prelicense education and application fees beyond just the exam itself, see ID-RES Certification Cost 2026: Complete Pricing Breakdown, and for the complete eligibility checklist see ID-RES Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
Your prelicense education has a three-year shelf life relative to your exam date - don't let coursework go stale before you schedule the ID-RES.

Building a Study Plan Around Domain Weight
Generic study techniques only matter to the extent they respect how the ID-RES actually weights content. Since License Law and Rules of the Idaho Real Estate Commission alone is 40% of the state portion, and Brokerage Representation is another 25%, a smart plan spends the majority of state-side study time on those two domains before touching the smaller ones.
National Foundations
- Real Property Characteristics, Legal Descriptions, and Property Use
- Forms of Ownership, Transfer, and Recording of Title
- Property Value and Appraisal
National Contracts, Practice, and Math
- Real Estate Contracts and Agency (largest national domain - prioritize)
- Real Estate Practice, Disclosures, Financing, and Settlement
- Real Estate Math Calculations drills
Idaho License Law and Agency
- License Law and Rules of the Idaho Real Estate Commission (40% of state portion)
- Brokerage Representation / Agency Law (25% of state portion)
Remaining State Domains and Full Simulation
- Idaho Principles and Practices, Licensing Requirements
- Duties and Powers of the Commission, Calculations and Closing Costs
- Full-length timed practice runs at four-hour pacing
Notice the practice runs in week four are timed at four hours, matching the actual exam clock - including the reality that break time counts against you. Rehearsing that constraint matters more for the ID-RES than for exams with untimed breaks. For a structured week-by-week plan with more detail, see the ID-RES Study Guide 2026: How to Pass on Your First Attempt, and once you're ready to test your recall under pressure, our practice test platform mirrors this domain weighting question by question.
After You Pass: Licensing and Renewal
Passing the ID-RES doesn't end your obligations to the Commission - it starts them. Your license must be renewed every two years, and the requirements differ depending on whether it's your first renewal:
- First active salesperson renewal: two Idaho Core courses plus 12 hours of post-license education
- Later active renewals: two Idaho Core courses plus 12 elective hours
Also remember the one-year validity rule: once you pass a portion, you have one year to pass the other portion (if you haven't already) and submit your license application. All of this must fall inside that single window, or you risk having to retest. This timing detail catches candidates who pass early, then delay their application while finishing other requirements.

Frequently Asked Questions
No. The ID-RES combines an 80-question national portion with a 40-question Idaho-specific state portion in one four-hour exam, scored separately, both administered through Pearson VUE under the Idaho Real Estate Commission.
No. Personal calculators are prohibited. Pearson VUE provides an on-screen calculator for the math questions, so it helps to practice with a similar tool beforehand.
A passed portion stays valid for one year. You must pass the remaining portion and submit your license application within that same one-year period, or the passed portion may no longer count.
Qualified active out-of-state licensees may be waived from the national portion and prelicense education, but they still must pass the Idaho-specific state portion.
License Law and Rules of the Idaho Real Estate Commission, which makes up 40% of the state portion - the single largest domain on that side of the exam.
