- You need 19 of 25 scored questions correct; five additional pretest items don't count toward your score.
- Licensing Law (Chapter 1102) carries 9 of 25 scored points - the single largest domain on the exam.
- You get 45 minutes for all 30 multiple-choice questions administered via Pearson VUE.
- Three failed attempts trigger a mandatory 20-hour Texas Law or 24-hour Texas Standards of Practice module before retesting.
What Passing Actually Means on the TX-PREI State Exam
The Texas Professional Real Estate Inspector Exam (TREC State Portion) is not scored on a curve, and it's not a percentage-based "70% to pass" test in the way many licensing exams are marketed. The Texas Real Estate Commission (TREC) sets a fixed numeric requirement: you must answer 19 of the 25 scored questions correctly. That's it. There's no partial credit, no weighting by difficulty, and no bonus for finishing early.
What trips up candidates is not knowing the exam actually contains 30 total questions, not 25. Five of those are unscored pretest items that TREC and Pearson VUE use to evaluate future exam content. You won't know which five are unscored, so every question deserves your full attention - but your pass/fail outcome hinges only on the 25 that count.
The Math Behind 19 of 25
Converted to a percentage, 19 of 25 works out to 76%. That number matters less than understanding where your margin for error actually lives. With only 25 scored items, missing 7 questions still passes you - but missing an 8th fails you. That's a razor-thin buffer once you consider how the questions are distributed across five very unevenly weighted domains.
This is why generic "study everything equally" advice doesn't work well for this particular exam. A candidate who is weak on one heavily-weighted domain and strong everywhere else can fail outright, while a candidate with moderate knowledge spread evenly across all five domains often passes comfortably. Understanding the weighting isn't optional strategy - it's arithmetic.
How the 25 Scored Questions Break Down
TREC's outline (administered through Pearson VUE, with the current state outline effective since September 2, 2014) allocates the 25 scored questions across five domains in fixed proportions: 2, 3, 3, 9, and 8. Here's how those numbers map to the actual content areas:
| Domain | Approx. Scored Questions | Focus |
|---|---|---|
| Domain 4: Licensing Law (Chapter 1102, Texas Occupations Code) | 9 | Largest domain - statutory licensing framework |
| Domain 5: General Provisions (TREC Rules, Chapter 535, Subchapter R) | 8 | Rules governing inspector conduct and practice |
| Domain 1: Structural Systems - Texas SOP Exclusions | 3 | Texas-specific reporting deviations from standard structural inspection |
| Domain 3: Mechanical Systems - Texas SOP Exclusions | 3 | Texas-specific reporting deviations for HVAC and mechanical items |
| Domain 2: Electrical Systems - Texas SOP Exclusions | 2 | Smallest domain - Texas-specific electrical reporting nuances |
Notice that the three "systems" domains (structural, electrical, mechanical) together only account for 8 of 25 points - the same as General Provisions alone. That's a signal worth internalizing: this is fundamentally a law-and-rules exam wearing an inspector's hat, not a technical building-science exam. For a full breakdown of what each domain actually tests, see the TX-PREI Exam Domains 2026 guide.
Domains 1-3: Systems Exclusions
These domains don't ask you to re-learn structural, electrical, or mechanical inspection from scratch. They test where the Texas Standards of Practice diverge from general inspection norms - what you're required (or not required) to report, and how Texas-specific exclusions change your documentation obligations.
- Know which components are explicitly excluded from mandatory reporting under Texas SOP
- Understand how exclusions differ across structural, electrical, and mechanical categories
- Focus on reporting language, not repair techniques
Why Licensing Law Carries the Most Weight
Domain 4, covering Chapter 1102 of the Texas Occupations Code, is the single largest scored domain at 9 of 25 questions - more than a third of your entire scored total. This domain covers the legal foundation of who can practice as a real estate inspector in Texas, licensing authority, and the statutory boundaries of the profession.
Pair that with Domain 5's 8 questions on TREC Rules (Chapter 535, Subchapter R), and you're looking at 17 of 25 scored questions - 68% of your entire score - coming from law and rules content rather than technical systems knowledge. If you only have time to master two domains deeply, these are the two.
Key Takeaway
Spend disproportionately more study time on Licensing Law and General Provisions than the systems domains combined - the point allocation makes this the highest-leverage decision you'll make in prep.
Format, Timing, and Test-Day Mechanics
The exam is administered as closed-book, computer-based testing at a Pearson VUE test center. You have 45 minutes to complete all 30 multiple-choice questions - scored and unscored combined. That works out to roughly a minute and a half per question, which is generous if you know the material but punishing if you're second-guessing licensing statute citations.
- Bring two unexpired signature IDs, including one primary government-issued photo ID, with names matching your registration exactly.
- Calculators are permitted but must not support alphabetic characters - leave anything with text-entry functions at home.
- This is a closed-book exam; no reference materials, printed statutes, or notes are allowed at the workstation.
Because the format is fixed and unchanging year over year, a lot of the "unknowns" candidates worry about are actually knowable in advance. The TX-PREI Cheat Sheet condenses the must-know statutory and rule references into a single review page, which is useful the night before your test date.
What Happens If You Don't Pass
A passing result on the state portion remains valid for one year, which matters if you're sequencing your national and state exams or waiting on other license application steps. If you don't clear 19 of 25, you can retest - but TREC builds in a specific consequence for repeated failure.
After three failed attempts at the state portion, you must complete either a 20-hour Texas Law module or a 24-hour Texas Standards of Practice module before you're reauthorized to sit for the exam again. This isn't optional remediation - it's a hard gate. It's also a strong argument for treating your first attempt seriously rather than planning to "learn the test" through repeated tries.
Eligibility and Fee Facts That Affect Prep
Passing score aside, TREC requires several eligibility conditions before you're even authorized to sit for the exam: candidates must be at least 18, be U.S. citizens or lawfully admitted, meet honesty/trustworthiness/integrity standards, and clear fingerprinting and background checks before receiving TREC authorization to test.
On the education side, TREC offers two alternative - not cumulative - paths to qualify:
- Substitute-education route: 194 total hours (154 coursework hours plus a 40-hour practicum).
- Sponsored route: 134 coursework hours, plus 12 months active as a Real Estate Inspector within the preceding 24 months, plus 175 supervised inspections.
Active licensure also requires maintaining at least $100,000 per-occurrence professional liability insurance or equivalent financial responsibility, and applications must be completed within one year of initiation. Under TREC Rule 535.210, the base Professional Inspector application fee is $120, with a $60 base timely renewal fee (renewal is required every two years, with online-system charges billed separately). Renewal itself requires 32 CE hours - 8 non-elective hours covering legal, ethics, standards-of-practice, and report-writing topics, plus 24 elective hours, with no more than 16 hours concentrated in a single subject.
None of these numbers directly change your 19-of-25 passing threshold, but they shape how much runway you have to prepare and retest.

Building a Domain-Weighted Study Plan
Given the fixed 2/3/3/9/8 allocation, a study plan that spends equal time on all five domains is mathematically inefficient. A domain-weighted approach - allocating study time roughly proportional to scored questions - gets you the most points per hour invested.
Licensing Law (Chapter 1102)
- Read through the statutory framework governing inspector licensure
- Drill practice questions specifically on Domain 4 topics
- Use short, focused review blocks rather than marathon sessions - this domain rewards repetition over cramming
General Provisions (TREC Rules, Subchapter R)
- Study TREC Rules governing inspector conduct and practice standards
- Cross-reference rules against real scenarios you might encounter on the job
- Combine review with Week 1 material in mixed practice sets
Structural and Mechanical SOP Exclusions
- Focus on what Texas SOP excludes from mandatory reporting
- Compare exclusion language across the two domains side by side
Electrical Exclusions and Full Timed Review
- Finish the smallest domain last since it carries the least weight
- Run full 30-question timed simulations under the 45-minute limit
- Review the complete TX-PREI Study Guide 2026 for gap-filling before test day
Practicing under realistic time pressure matters more than most candidates expect. Working through timed sets on the TX-PREI practice test platform lets you feel the actual 45-minute pace before you're sitting in a Pearson VUE testing center, and repeated exposure to Domain 4 and Domain 5 question styles builds the pattern recognition that a percentage-based study plan alone won't give you.
