Exam Snapshot: Numbers to Memorize
Before you touch a single domain outline, lock in the mechanical facts of the IA-RES. These numbers show up in how you pace yourself on exam day, and they're the kind of detail that trips up otherwise well-prepared candidates. The exam is administered by PSI on behalf of the Iowa Real Estate Commission, part of the Iowa Department of Inspections, Appeals, and Licensing, and it costs $95 per attempt.
- Total scored questions: 120 (80 national + 40 Iowa state)
- Unscored experimental items: 5 to 10, mixed in without identification
- Time allowed: 180 minutes total
- Passing threshold: 56 of 80 national questions, 28 of 40 state questions
- Delivery options: PSI test center or remote proctoring
- Result validity: through the last working day of the sixth month after passing

If you want the exact score math explained line by line, the IA-RES Passing Score 2026: Exactly What You Need to Pass guide walks through both cut scores independently.
National Domains 1-11 at a Glance
Domains 1 through 11 make up the national portion and cover concepts tested across most U.S. real estate licensing exams. Here is the weighting breakdown, condensed for quick review.
| Domain | Topic | Weight |
|---|---|---|
| 1 | Property Ownership | 10% |
| 2 | Land Use Controls | 5% |
| 3 | Valuation | 8% |
| 4 | Financing | 10% |
| 5 | Contracts | 19% |
| 6 | Agency | 13% |
| 7 | Property Disclosures | 7% |
| 8 | Property Management | 3% |
| 9 | Transfer of Title | 6% |
| 10 | Practice of Real Estate | 12% |
| 11 | Real Estate Calculations | 7% |
Domain 6: Agency (13%)
The second-largest national domain. Candidates must clearly distinguish fiduciary duties, types of agency relationships, and disclosure obligations to buyers and sellers.
- Know the fiduciary duties owed to a client versus a customer
- Understand dual agency and designated agency distinctions
- Be ready for scenario questions, not just definitions
Domain 10: Practice of Real Estate (12%)
This domain tests day-to-day operational knowledge: advertising rules, license law application, and professional conduct scenarios that mirror what a new salesperson actually encounters.
- Fair housing advertising compliance
- Proper handling of earnest money and client funds
- Supervision requirements between agents and brokers

Iowa Domains 12-23 at a Glance
Domains 12 through 23 are unique to Iowa and make up the 40-question state portion. These questions reference the Iowa Real Estate Commission's rules directly, so generic national prep will not cover them.
- Domain 12: Licensing Requirements
- Domain 13: License Maintenance
- Domain 14: Disciplinary Actions - Suspension, Revocation and Voluntary Compliance
- Domain 15: Real Estate Education
- Domain 16: Trust Accounts
- Domain 17: Contracts
- Domain 18: Agency
- Domain 19: Property Disclosure Requirements
- Domain 20: Iowa Civil Rights Act of 1965
- Domain 21: Unlicensed Assistants
- Domain 22: Broker Responsibilities
- Domain 23: Property Management
Domain 16: Trust Accounts
Trust account handling is a favorite testing area because errors here carry real disciplinary consequences in practice. Know deposit timelines, commingling prohibitions, and record-keeping duties tied to broker responsibilities in Domain 22.
Domain 20: Iowa Civil Rights Act of 1965
This state-specific fair housing law extends beyond federal protections. Candidates should be able to identify protected classes under Iowa law specifically, not just the federal list.
Key Takeaway
Do not assume national fair housing knowledge covers Domain 20. Study the Iowa Civil Rights Act of 1965 as its own topic with its own protected-class list.
Why Contracts Dominates Both Sections
Contracts appears twice in the domain list - as Domain 5 nationally (19%, the single largest national weight) and again as Domain 17 on the Iowa side, where it is also the largest state domain. That means contract law questions can appear from two different angles: general contract principles (offer, acceptance, consideration, capacity, statute of frauds) and Iowa-specific contract forms, disclosure timing, and remedies.
Treat Contracts as a single study unit that gets revisited twice - once for the universal legal concepts, once for how Iowa applies them. Skipping either half leaves points on the table in the highest-weighted domain on the exam.
Registration and Eligibility Mechanics
Before you can even schedule the IA-RES, you need to satisfy prelicense education requirements set by the Iowa Real Estate Commission:
- A Commission-approved 60-hour prelicense course, completed within the 12 months immediately before your exam date
- Minimum age of 18
- Three additional 12-hour live courses required for original licensure (separate from the 60-hour course)
- A national criminal history check
- Errors-and-omissions insurance coverage
- A sponsoring broker to hold your license once issued
The $95 exam fee covers a single sitting. Once you pass, your results remain valid only through the last working day of the sixth month after your passing date, so don't let licensing paperwork sit too long after testing. Full eligibility detail, including how the timing windows interact, is covered in IA-RES Requirements 2026: Eligibility, Prerequisites & How to Qualify, and the complete cost picture - course fees, insurance, and the exam fee together - is broken down in IA-RES Certification Cost 2026: Complete Pricing Breakdown.
After licensure, maintaining active status requires 36 continuing-education hours every three-year renewal cycle: 8 hours of Law Update, 4 hours of Ethics, and 24 elective hours, with at least 12 of those 36 hours completed through live instruction rather than self-study formats.
Final-Week Review Schedule
In the last stretch before your scheduled test, structure your remaining review time around domain weight rather than domain number order. This is the one place a generic study technique - spaced repetition of weak-area flashcards - pays off specifically for the IA-RES, because the domain weights tell you exactly which cards deserve the most repetitions.
Contracts, both sides
- Review Domain 5 (national, 19%) and Domain 17 (Iowa) together
- Drill offer/acceptance scenarios and Iowa-specific contract forms
Agency and Licensing
- Cover Domain 6 (13%) and Domain 18 (Iowa agency)
- Review Domain 12 Licensing Requirements and Domain 13 License Maintenance
Financing, Valuation, Practice
- Domain 4 Financing (10%), Domain 3 Valuation (8%), Domain 10 Practice of Real Estate (12%)
- Work Domain 11 Real Estate Calculations problems by hand, no calculator shortcuts
Iowa-only cleanup
- Trust Accounts, Disciplinary Actions, Unlicensed Assistants, Iowa Civil Rights Act of 1965
- Light review only - no new material the night before

Test Day Checklist
Whether you test at a PSI center or via remote proctoring, the mechanics of the day matter as much as your content knowledge.
- Arrive (or log in for remote proctoring) with valid, unexpired photo ID matching your registration name exactly
- Budget your 180 minutes across 120 scored questions - roughly 1.5 minutes per question, leaving buffer for calculation items in Domain 11
- Remember that 5 to 10 unscored experimental questions are mixed in unlabeled; don't waste time trying to identify them
- Flag uncertain questions and return to them rather than freezing your pace on one item
- Confirm your remote-proctoring workspace meets PSI requirements the night before if you chose that delivery option
Key Takeaway
Because national and state sections are scored separately, mentally treat the exam as two back-to-back tests rather than one continuous 120-question block.
Once you're licensed, opportunities open with residential brokerages, property management firms, and commercial teams across Iowa that need agents versed in both national practice standards and Iowa-specific compliance.

Frequently Asked Questions

Your passing result remains valid through the last working day of the sixth month after the date you passed, so complete your licensing steps within that window.
Contracts, since it's the largest domain on both the national side (Domain 5, 19%) and the Iowa side (Domain 17), makes it the single highest-value topic to master.
