- TX-PREI is TREC's state-portion exam: 30 questions (25 scored, 5 pretest), 45 minutes, via Pearson VUE.
- You need 19 of 25 scored questions correct to pass - there's no partial credit for pretest items.
- Licensing Law carries the heaviest weight of the five scored domains, out of allocations of 2, 3, 3, 9, and 8.
- Passing results are valid for one year, and you must complete your application within one year too.
What Is A TX-PREI, Exactly?
TX-PREI refers to the Texas Professional Real Estate Inspector Exam - the TREC State Portion. It's the Texas-specific licensing exam administered through Pearson VUE on behalf of the Texas Real Estate Commission (TREC), and it's the piece of the licensing puzzle that tests whether you understand Texas inspection law, TREC's rules, and the state's specific reporting requirements - not general home inspection knowledge.
This is a critical distinction: the state portion is separate from the National Home Inspector Examination (NHIE). Candidates pursuing full Professional Inspector licensure in Texas need to pass both, but they are different tests with different content, different scoring, and different administration details. If you've landed here searching "what is a TX-PREI," you're looking specifically at the state-law-and-rules exam, not the national content exam. For a broader breakdown of what the credential covers day to day, see What Is TX-PREI? and TX-PREI Meaning.
Who Takes This Exam and Why It Exists
The state portion exists because TREC needs assurance that licensed inspectors in Texas understand Texas-specific law and practice - things a national exam simply can't cover. Candidates taking this exam are typically working toward Professional Inspector licensure through one of two paths TREC recognizes: a substitute-education route or an alternative sponsored route (more on those below). Neither path is optional filler; each is designed to produce inspectors who can walk into a Texas home, apply the Texas Standards of Practice correctly, and know exactly what the law requires them to disclose, document, and report.
People preparing for this exam are usually already deep into a career transition - many come from construction, code enforcement, real estate, or general contracting backgrounds and are formalizing their expertise into a state-recognized inspector license. If you're wondering whether the credential is worth the time investment relative to the work it opens up, Is the TX-PREI Certification Worth It? Complete ROI Analysis 2026 and TX-PREI Jobs dig into that question in more depth.
Exam Format: 30 Questions, 45 Minutes, One Attempt at a Time
The mechanics of this exam are tight, and understanding them changes how you prepare. The state examination contains 30 multiple-choice questions total - but only 25 are scored. The remaining five 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 full attention.
You have 45 minutes to complete all 30 questions, and you need to answer 19 of the 25 scored questions correctly to pass. That's a demanding ratio given the time limit, which means pacing matters as much as knowledge. For a full breakdown of exactly what score you need and how it's calculated, see TX-PREI Passing Score 2026: Exactly What You Need to Pass.
Testing happens at a Pearson VUE test center in a closed-book, computer-based format. You'll need two unexpired signature IDs, with at least one being a primary government-issued photo ID, and the names on both must match your registration exactly. If you use a calculator, it cannot support alphabetic characters - a small detail that trips up candidates who bring the wrong device on test day.
Key Takeaway
With only 45 minutes for 30 questions, you have roughly 90 seconds per question. Practicing under timed conditions matters more here than for exams with generous time allowances.
The Five Domains Inside the State Portion
The state exam outline breaks scored content into five domains, and the point allocations are not evenly distributed. Out of the 25 scored questions, the breakdown runs 2, 3, 3, 9, and 8 - meaning two domains do the heavy lifting. Understanding this weighting is the single most useful thing you can do before you open a study guide.
Domain 1: Structural Systems - Texas SOP Exclusions and Unique Reporting Requirements
Focuses on where the Texas Standards of Practice diverge from general structural inspection norms, plus what must (and must not) be reported.
- Know which structural elements are explicitly excluded from required reporting under Texas rules
Domain 2: Electrical Systems - Texas SOP Exclusions and Unique Reporting Requirements
Covers the same exclusion-and-reporting logic applied to electrical systems specifically.
- Distinguish general electrical inspection knowledge from Texas-mandated reporting language
Domain 3: Mechanical Systems - Texas SOP Exclusions and Unique Reporting Requirements
Applies the exclusion framework to mechanical systems, testing your grasp of what Texas requires versus what a national standard might.
- Memorize the reporting phrases and disclosure obligations unique to Texas mechanical inspection findings
Domain 4: Licensing Law - Chapter 1102, Texas Occupations Code
The largest domain on the exam at 9 of 25 scored questions. This is pure statute: who can be licensed, how licenses work, what's prohibited, and the legal structure governing inspectors in Texas.
- Study Chapter 1102 directly rather than relying only on paraphrased summaries
Domain 5: General Provisions - TREC Rules, Chapter 535, Subchapter R
The second-largest domain at 8 of 25 scored questions. This covers TREC's administrative rules specific to real estate inspectors - separate from the statute itself but tightly linked to it.
- Learn to distinguish statute-level rules (Domain 4) from TREC's administrative rules (Domain 5)
Together, Licensing Law and General Provisions account for 17 of the 25 scored questions - more than two-thirds of your score. That doesn't mean you can skip the three systems-based domains (Structural, Electrical, Mechanical), since 8 combined points can still make or break a 19-out-of-25 pass threshold. For a deeper walkthrough of each domain with example question styles, see TX-PREI Exam Domains 2026: Complete Guide to All 5 Content Areas.
| Domain | Scored Questions | Share of Exam |
|---|---|---|
| Structural Systems (SOP Exclusions/Reporting) | 2 | Smallest |
| Electrical Systems (SOP Exclusions/Reporting) | 3 | Small |
| Mechanical Systems (SOP Exclusions/Reporting) | 3 | Small |
| Licensing Law (Chapter 1102) | 9 | Largest |
| General Provisions (TREC Rules, Ch. 535 Subchapter R) | 8 | Second Largest |
Getting to the Testing Chair: Eligibility and Paperwork
Before you can even schedule the state portion, TREC requires you to meet a set of eligibility conditions. You must be at least 18 years old, a U.S. citizen or lawfully admitted resident, and able to satisfy TREC's honesty, trustworthiness, and integrity requirements. Fingerprints and a background check are mandatory, followed by formal TREC authorization to test.
On the education side, TREC recognizes two distinct paths - and they are alternatives to each other, not requirements you stack together:
- Substitute-education route: 194 total hours, broken into 154 coursework hours plus a 40-hour practicum.
- Alternative sponsored route: 134 coursework hours, combined with 12 months of active experience as a Real Estate Inspector during the preceding 24 months, plus 175 supervised inspections.
Once you're ready to apply, you have one year to complete the application process. If you're taking both the national and state exams separately, remember the sequencing rule: the national examination comes first, then the state portion. Passing results are only valid for one year, so timing your national exam, state exam, and application submission within that window takes real planning. A full eligibility checklist lives at TX-PREI Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Fees, Renewal, and the Ongoing CE Cycle
Under TREC Rule 535.210, the base Professional Inspector application fee is $120, and the base timely renewal fee is $60 - both separate from any online-system processing charges Pearson VUE or TREC's portal may add. Once licensed, renewal happens every two years and requires 32 hours of continuing education. Of those 32 hours, eight must be non-elective, covering legal, ethics, standards-of-practice, and report-writing topics, while the remaining 24 are elective - with a cap of no more than 16 hours in any single subject area.
Maintaining your required insurance or financial responsibility throughout each renewal cycle is also mandatory; letting it lapse can jeopardize your active license status regardless of your CE hours. For the complete fee picture across application, testing, and renewal, see TX-PREI Certification Cost 2026: Complete Pricing Breakdown.
What Happens If You Don't Pass
Because the pass threshold (19 of 25) is unforgiving for a 45-minute exam, retakes are common and nothing to be ashamed of. But TREC does build in a checkpoint: 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 test again. This isn't punitive - it's designed to close specific knowledge gaps that repeated attempts reveal, usually in Licensing Law or General Provisions given how heavily those domains are weighted.

Building a Study Plan Around the Domain Weighting
Generic study techniques - spaced repetition, timed drills, active recall - all work fine here, but they only pay off when applied against the actual weighting of this exam. Spending equal time across all five domains wastes hours on Structural, Electrical, and Mechanical exclusions (8 combined points) when Licensing Law and General Provisions alone account for 17.
Chapter 1102 and TREC Rule Fundamentals
- Read Chapter 1102 of the Texas Occupations Code directly
- Study TREC Rules, Chapter 535, Subchapter R alongside it to see how statute and rule interact
SOP Exclusions Across Systems
- Compare Texas SOP exclusions for structural, electrical, and mechanical systems side by side
- Drill the specific reporting language required for each system
Timed Practice Under Real Conditions
- Run full 30-question, 45-minute practice sessions to build pacing instinct
- Review missed items by domain to spot whether gaps cluster in Licensing Law or elsewhere
For a structured, week-by-week version of this plan with more detail on pacing and review cycles, see TX-PREI Study Guide 2026: How to Pass on Your First Attempt. And when you're in the final review stretch, a condensed reference like TX-PREI Cheat Sheet 2026: One-Page Review of Must-Know Facts can help you consolidate the Chapter 1102 and Subchapter R details that carry the most weight.
After You Pass: What the Credential Opens Up
Passing the state portion is one part of qualifying for Professional Inspector licensure in Texas, alongside the national exam, your education route, background check, and insurance requirement. Once licensed, you're positioned to work independently or with an inspection firm, performing the residential and light commercial inspections that Texas real estate transactions routinely require. If you're mapping out how licensure translates into actual career paths and pay, TX-PREI Salary Guide 2026: Complete Earnings Analysis and TX-PREI Jobs are useful next reads, and TX-PREI Training covers ongoing skill-building beyond the exam itself.
Whichever stage you're at - just discovering what the acronym means, or deep into Chapter 1102 review - testing your recall against realistic, timed questions at TX-PREI Exam Prep's practice platform is the fastest way to see where your 19-of-25 threshold actually stands today.
Frequently Asked Questions
No. TX-PREI refers specifically to the TREC state-portion exam. The National Home Inspector Examination (NHIE) is a separate exam required for full Texas licensure, and if taken separately, the national exam must come before the state portion.
The exam has 30 multiple-choice questions total - 25 scored and 5 unscored pretest items - with 45 minutes to complete the entire test.
Licensing Law (Chapter 1102, Texas Occupations Code) carries the most scored questions at 9 of 25, followed by General Provisions (TREC Rules, Chapter 535, Subchapter R) at 8 of 25. Together they make up more than two-thirds of your score.
After three failed attempts, TREC requires completion of either a 20-hour Texas Law module or a 24-hour Texas Standards of Practice module before you can be reauthorized to test again.
Passing results remain valid for one year, so it's important to align your national exam, state exam, and licensing application submission within that window.
