What the TX-PREI State Exam Actually Tests
The Texas Professional Real Estate Inspector Exam (TREC State Portion) is the state-law and Texas-specific rules companion to the national inspector exam. It is administered by Pearson VUE on behalf of the Texas Real Estate Commission (TREC), and it is entirely distinct from the National Home Inspector Examination (NHIE) that candidates take as part of full licensure. If you're taking both portions separately, TREC requires you to sit for the national exam first and the state portion second - plan your study calendar accordingly.
Where the NHIE tests general home inspection knowledge across the country, the TREC state portion narrows in on Texas Standards of Practice exclusions, unique reporting requirements, and the statutory framework that governs how a Texas-licensed inspector must operate. If you want a deeper breakdown of how this exam differs from other credentials people confuse with the same acronym, see What Is TX-PREI? and TX-PREI Meaning for clarification before you start studying.
Exam Format: 30 Questions, 45 Minutes, One Shot
The state examination is short and tightly timed: 30 multiple-choice questions total, of which 25 are scored and five are unscored pretest items you cannot identify during the test. You have 45 minutes to complete all 30 questions. To pass, you must answer 19 of the 25 scored questions correctly.
Because the unscored items are mixed in randomly, there's no strategy for "skipping" pretest questions - you simply need to be accurate across the board. At roughly 90 seconds per question, pacing matters, but the real bottleneck for most candidates isn't time, it's precision on Licensing Law details. For a full walkthrough of exactly what score you need and how it's calculated, read TX-PREI Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
With only 25 scored questions, missing seven is the maximum margin for error. Every domain matters, but errors on Licensing Law questions are the most costly since that domain has the largest question count.
The Five TREC State-Portion Domains
The Pearson VUE state content outline (effective September 2, 2014, and still linked from the inspector testing page) breaks the 25 scored questions into five domains. The official allocations are 2, 3, 3, 9, and 8 questions respectively, with Licensing Law by far the largest single domain.
Domain 1: Structural Systems - Texas SOP Exclusions and Unique Reporting Requirements
Focuses on what the Texas Standards of Practice explicitly excludes inspectors from reporting on regarding foundations, framing, and structural components, plus how findings must be documented differently than in generic national standards.
- Know which structural conditions are outside the scope of a Texas SOP inspection
Domain 2: Electrical Systems - Texas SOP Exclusions and Unique Reporting Requirements
Covers exclusions and mandatory reporting language specific to electrical systems under Texas rules, distinct from general electrical inspection knowledge tested elsewhere.
- Memorize what must always be noted versus what falls outside SOP scope
Domain 3: Mechanical Systems - Texas SOP Exclusions and Unique Reporting Requirements
Tests the same exclusion/reporting logic applied to HVAC and other mechanical systems as defined by Texas rule text.
- Focus on reporting phrasing requirements, not repair techniques
Domain 4: Licensing Law - Chapter 1102, Texas Occupations Code
The largest domain by far, with 9 of 25 scored questions. This covers the statutory basis for inspector licensure, including definitions, license categories, disciplinary authority, and legal obligations under Chapter 1102.
- Study definitions and licensing categories word-for-word
- Know TREC's enforcement and disciplinary powers
Domain 5: General Provisions - TREC Rules, Chapter 535, Subchapter R
With 8 of 25 scored questions, this domain covers the administrative rules governing real estate inspectors - practice requirements, standards administration, and procedural rules that sit alongside the statutory law in Domain 4.
- Distinguish between statute (Chapter 1102) and rule (Chapter 535, Subchapter R)
Because Domains 4 and 5 together account for 17 of the 25 scored questions, more than two-thirds of your score depends on legal and regulatory knowledge rather than technical system knowledge. For a question-by-question breakdown of study priorities within each domain, see the TX-PREI Exam Domains 2026: Complete Guide to All 5 Content Areas.
| Domain | Scored Questions | Share of 25 |
|---|---|---|
| Structural Systems (SOP Exclusions) | 2 | Smallest |
| Electrical Systems (SOP Exclusions) | 3 | Small |
| Mechanical Systems (SOP Exclusions) | 3 | Small |
| Licensing Law (Ch. 1102) | 9 | Largest |
| General Provisions (Ch. 535 Subch. R) | 8 | Second-largest |
Registration, Fees, and Eligibility Mechanics
Before you can schedule the state portion, TREC must authorize you to test. Eligibility requires being at least 18 years old, being a U.S. citizen or lawfully admitted, satisfying TREC's honesty/trustworthiness/integrity standards, and completing fingerprints and a background check. You must also finish your application within one year of starting it.
Education can be satisfied one of two ways - these are alternatives, not stacked requirements:
- 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 and 175 supervised inspections
Under TREC Rule 535.210, the base Professional Inspector application fee is $120, with a $60 base timely renewal fee - both separate from Pearson VUE's own online scheduling and administration charges. Active licensure also requires at least $100,000 per-occurrence professional liability insurance or equivalent financial responsibility. For the complete eligibility checklist, including the fingerprinting and background-check steps, see TX-PREI Requirements 2026: Eligibility, Prerequisites & How to Qualify, and for a full cost breakdown including renewal cycles, check TX-PREI Certification Cost 2026: Complete Pricing Breakdown.
A Domain-Weighted Study Timeline
Because Licensing Law and General Provisions together make up 17 of 25 scored questions, your study calendar should mirror that weighting rather than splitting time evenly across five domains. A four-week runway before test day works well for most candidates layering state-portion prep on top of their coursework.
Chapter 1102, Texas Occupations Code
- Read the statute section by section; build a glossary of licensing definitions
- Drill disciplinary and enforcement authority questions daily
Chapter 535, Subchapter R Rules
- Compare rule language against statute language to avoid confusing the two
- Focus on practice requirements and administrative procedures
SOP Exclusions Across Structural, Electrical, Mechanical
- Build a single reference sheet of what's excluded from reporting in each system
- Practice distinguishing exclusion language from reporting-requirement language
Timed Practice and Weak-Spot Review
- Run full 30-question, 45-minute timed sets to build pacing instincts
- Revisit any domain where you're missing more than one question consistently

Test Day at Pearson VUE: What to Bring
The state exam is closed-book and computer-based at a Pearson VUE test center. You'll need two unexpired signature IDs, one of which must be a primary government-issued photo ID, and both names must match your test registration exactly. If you plan to bring a calculator, make sure it does not support alphabetic characters - anything with letter keys or text-storage functions will be rejected at check-in.
- Arrive with proper identification matching your registration name precisely
- No study materials, phones, or notes permitted in the testing room
- Confirm your appointment details in advance through Pearson VUE's system
Because this is a short, 45-minute appointment, there's little room to recover from a slow start caused by ID issues or unfamiliarity with the check-in process. Review the current scheduling windows and any blackout considerations in TX-PREI Exam Dates 2026: Testing Windows, Deadlines & Scheduling before you book.
What Happens If You Fail
Passing results are valid for one year, giving you a defined window to complete the rest of your licensing steps once you clear the state portion. But if you fail three times, TREC requires you to complete either a 20-hour Texas Law module or a 24-hour Texas Standards of Practice module before you're reauthorized to test again. That's a meaningful time investment, so it's worth treating your first attempt seriously rather than planning to "learn from" an early fail.
Key Takeaway
Three failed attempts trigger a mandatory remedial course - plan your first attempt as if it's your only shot, especially on the Licensing Law domain.
Who Hires Licensed Inspectors in Texas
Once licensed, Professional Real Estate Inspectors in Texas typically work independently, join established inspection firms, or partner with real estate brokerages that refer inspection clients. Demand tends to track residential real estate transaction volume across Texas metro areas.

For candidates who are still early in the process and want the broader picture of the credential itself - including how it differs from other things sharing similar naming - start with TX-PREI Certification and What Is TX-PREI Certification? before diving into state-portion specifics.
Once you've mapped out your eligibility path and education route, the fastest way to convert study time into a passing score is targeted practice under real exam conditions. You can start running timed, domain-weighted practice questions on the main practice test site to get comfortable with the 45-minute pace before your actual appointment.
If terminology mix-ups are still tripping you up - including confusion with other credentials that happen to share the same four letters - the clarifying posts What Does TX-PREI Stand For?, What Is A TX-PREI?, and What Does TX-PREI Mean? are worth a quick read, alongside TX-PREI Training for coursework provider considerations.

FAQ
The exam has 30 questions total: 25 scored and 5 unscored pretest items. You need 19 of the 25 scored questions correct, meaning you can miss no more than 6 and still pass.
No. The state portion is Texas-specific and administered separately from the NHIE. If taking both, TREC requires the national exam to be completed before the state exam.
Licensing Law (Chapter 1102, Texas Occupations Code) carries 9 of 25 scored questions, the most of any domain, followed by General Provisions (Chapter 535, Subchapter R) with 8. Together they're over two-thirds of your score.
After three failures, TREC requires completion of a 20-hour Texas Law module or a 24-hour Texas Standards of Practice module before you can be reauthorized to retest.
Bring two unexpired signature IDs, including one primary government-issued photo ID, with names that exactly match your test registration. Calculators are allowed only if they don't support alphabetic characters.
