- The IA-REB exam has 23 total domains: 11 national (75 questions, 80 points) and 12 Iowa-specific (40 questions, 40 points).
- Contracts is the single largest national domain at 19% of the national score.
- Broker Responsibilities is the largest Iowa-specific domain among Domains 12-23.
- You need 60 of 80 national points and 30 of 40 state points to pass - domain-by-domain gaps matter more than overall averages.
Exam Overview: How the Domains Fit Together
The Iowa Real Estate Broker Exam (IA-REB) is built around 23 distinct content areas, split into two very different scoring blocks. Domains 1 through 11 make up the national portion - 75 questions worth 80 points, covering broad real estate principles tested across most U.S. jurisdictions. Domains 12 through 23 make up the Iowa-specific portion - 40 questions worth 40 points, covering the statutes, rules, and licensing procedures unique to Iowa. Together, the exam totals 115 scored questions worth 120 points, delivered in a single 180-minute session administered by PSI on behalf of the Iowa Real Estate Commission within the Iowa Department of Inspections, Appeals, and Licensing.
You may also encounter 5 to 10 additional unscored experimental questions mixed into the exam. These are indistinguishable from scored items, so every question deserves full attention regardless of which domain it appears to test.
National Domains 1-11: What They Cover
The national domains reflect general real estate practice knowledge and account for the majority of the exam's raw question count. Each domain carries a specific weight of the 80 national points, and understanding those weights tells you exactly where to invest study hours.
Domain 1: Property Ownership (10%)
Covers estates in land, forms of ownership, and the legal rights that come with holding real property.
- Fee simple, life estates, and concurrent ownership structures
Domain 2: Land Use Controls (5%)
Covers zoning, deed restrictions, and government controls that limit how property can be used.
- Public vs. private land use restrictions
Domain 3: Valuation (8%)
Covers appraisal approaches and the factors that influence market value opinions.
- Sales comparison, cost, and income approaches
Domain 4: Financing (9%)
Covers mortgage instruments, loan types, and the financing process buyers navigate.
- Conventional vs. government-backed loan features
Domain 5: Contracts (19%)
The single largest national domain. Covers contract formation, essential elements, and remedies for breach.
- Listing agreements, purchase agreements, and contingencies
Domain 6: Agency (13%)
Covers agency relationships, fiduciary duties, and disclosure obligations between brokers and clients.
- Types of agency and duties owed to each party
Domain 7: Property Disclosures (7%)
Covers what must be disclosed to buyers about a property's condition and history.
- Material fact disclosure standards
Domain 8: Property Management (5%)
Covers landlord-tenant relationships and management responsibilities at a national level.
- Lease structures and management duties
Domain 9: Transfer of Title (6%)
Covers deeds, title transfer mechanics, and closing processes.
- Deed types and recording requirements
Domain 10: Practice of Real Estate (12%)
Covers day-to-day brokerage practice, including advertising, fair housing, and licensee conduct.
- Federal fair housing law application
Domain 11: Real Estate Calculations (6%)
Covers the math candidates must perform quickly and accurately during the exam.
- Commission splits, prorations, and loan-to-value ratios
Because Contracts and Agency together represent nearly a third of the national point total, candidates who feel shaky on either topic should prioritize them early. The IA-REB Cheat Sheet is a useful quick-reference once you've built a foundation in these higher-weight domains.
Iowa-Specific Domains 12-23: What They Cover
The Iowa-specific block is where many candidates lose points they didn't expect to lose - not because the material is harder, but because it's unfamiliar if you only studied general real estate principles. These 12 domains draw directly from Iowa Real Estate Commission rules and Iowa Code.
Domain 12: Licensing Requirements
Covers who needs a license, license categories, and the pathway from salesperson to broker.
- Broker licensure requires 24 months of active salesperson experience before application
Domain 13: License Maintenance
Covers renewal cycles, status changes, and keeping a license active in good standing.
Domain 14: Disciplinary Actions - Suspension, Revocation and Voluntary Compliance
Covers Commission enforcement authority and the process behind disciplinary outcomes.
Domain 15: Real Estate Education
Covers prelicense and continuing education rules specific to Iowa.
- 60 hours of Commission-approved prelicense education required within 24 months of the exam
Domain 16: Trust Accounts
Covers proper handling of client funds and trust account recordkeeping obligations.
Domain 17: Contracts
The Iowa-specific counterpart to national contract law, focused on Iowa forms and practice.
Domain 18: Agency
Covers Iowa's specific agency disclosure statutes and representation rules.
Domain 19: Prop Disclosure Requirements
Covers Iowa's statutory seller disclosure obligations.
Domain 20: Iowa Civil Rights Act of 1965
Covers state-level fair housing protections that go beyond federal law.
Domain 21: Unlicensed Assistants
Covers what unlicensed personnel may and may not do in an Iowa brokerage.
Domain 22: Broker Responsibilities
The largest Iowa domain. Covers supervisory duties a designated broker owes to affiliated licensees and clients.
- Supervision, recordkeeping, and office management obligations
Domain 23: Property Management
Covers Iowa-specific property management statutes distinct from the national Domain 8 content.
Key Takeaway
Since Broker Responsibilities carries the most weight in the Iowa block, candidates should treat supervisory duties, trust account rules, and disciplinary procedures as a connected cluster rather than isolated facts.
How Domain Content Is Actually Tested
Knowing the domain list is only half the battle - the question format changes how you should study. The national portion uses scenario-based, best-answer questions, some presenting as many as eight answer options. Rather than a single correct choice, several options may earn partial credit: answers can be worth zero, one, or two points depending on how well they address the scenario.
This scoring structure rewards candidates who can rank options by quality, not just identify a "right" and "wrong" answer. Memorizing definitions from Domains 1-11 in isolation won't be enough; you need to practice applying them inside realistic broker scenarios. This is one reason a resource like the full practice test platform is worth working through - repeated exposure to multi-option, partial-credit style questions builds the judgment the exam actually measures.
Eligibility and Registration Mechanics
Domain mastery only matters if you're eligible to sit for the exam in the first place. Iowa requires 60 hours of Commission-approved broker prelicense education completed within 24 months before your exam date, plus 24 months of active salesperson experience before you can apply for a broker license. Original licensure also requires a criminal history investigation and proof of errors-and-omissions insurance.
- Exam fee: $95, paid through PSI's registration process
- Delivery options: test-center or remote-proctored, both administered by PSI
- Time allowed: 180 minutes for all 115 scored questions plus any experimental items
- Results validity: through the last working day of the sixth month after your passing date
Because results have a firm expiration window, candidates should plan the licensing application steps that follow a pass before sitting the exam, not after. The IA-REB Requirements guide walks through eligibility documentation in more detail, and the IA-REB Exam Dates guide covers scheduling logistics with PSI. For a full accounting of what the exam and licensing pathway cost beyond the $95 fee, see the IA-REB Certification Cost breakdown.
Mapping a Study Timeline to the Domains
Rather than studying domains in numerical order, allocate time based on point weight and personal weak spots. A practical way to structure preparation is to front-load the heaviest national domains, then dedicate focused blocks to the Iowa-specific cluster before a final integration pass.
Highest-Weight National Domains
- Domain 5: Contracts (19%)
- Domain 6: Agency (13%)
- Domain 10: Practice of Real Estate (12%)
Remaining National Domains
- Domains 1, 3, 4, 9, 11: Ownership, Valuation, Financing, Transfer of Title, Calculations
- Domains 2, 7, 8: Land Use Controls, Disclosures, Property Management
Iowa Statutory Core
- Domain 22: Broker Responsibilities
- Domain 12: Licensing Requirements
- Domain 16: Trust Accounts
- Domain 14: Disciplinary Actions
Remaining Iowa Domains and Full Review
- Domains 13, 15, 17-21, 23
- Timed practice sessions mirroring the 180-minute, 115-question format
This sequencing lines up with how the exam is scored: you need 60 of 80 national points and 30 of 40 state points independently, so it's inefficient to over-study one block while neglecting the other. For a complete week-by-week methodology beyond domain sequencing, see the IA-REB Study Guide.
| Block | Domains | Questions | Points | Passing Threshold |
|---|---|---|---|---|
| National | 1-11 | 75 | 80 | 60 points |
| Iowa-Specific | 12-23 | 40 | 40 | 30 points |
