What Is TX-PREI?

TL;DR
  • TX-PREI is the TREC-administered state-portion exam: 30 questions (25 scored, 5 pretest), 45 minutes.
  • You must answer 19 of 25 scored questions correctly to pass the state portion.
  • Licensing Law (Chapter 1102) carries the largest scored-item allocation of the five domains.
  • The state exam is separate from the National Home Inspector Examination (NHIE) required for licensure.

What Is TX-PREI?

TX-PREI refers to the Texas Professional Real Estate Inspector Exam - specifically the state portion of the licensing exam administered on behalf of the Texas Real Estate Commission (TREC). It is one half of what a candidate must pass to become a licensed Professional Inspector in Texas; the other half is the National Home Inspector Examination (NHIE), which covers general inspection knowledge tested nationwide. TX-PREI, by contrast, is laser-focused on how Texas law, TREC rules, and Texas-specific Standards of Practice (SOP) modify or exclude what a national exam would otherwise expect.

If you're researching this credential for the first time, it helps to think of it less as a broad inspection competency test and more as a compliance and procedure exam. It checks whether you understand the legal framework you'll operate under once you're inspecting homes in Texas - not whether you can identify every possible mechanical defect. For a deeper breakdown of exactly what's tested, see the TX-PREI Exam Domains 2026 guide.

Not to Be Confused With: TX-PREI (state portion) is distinct from the NHIE. Candidates taking both portions separately should complete the national exam before attempting the state exam.

Who Administers the State Portion

TREC sets the licensing requirements and rules, but Pearson VUE administers the actual Professional Inspector state examination at computer-based test centers. The exam is closed-book. You'll need two unexpired signature IDs at check-in, including at least one primary government-issued photo ID, and the names on both must match your test registration exactly. If you plan to bring a calculator, it must not support alphabetic characters - a small detail that trips up candidates who show up with the wrong device.

The Pearson VUE state content outline used for TX-PREI lists September 2, 2014 as its effective date, and that outline remains the document linked from the inspector testing page today. That's the source document worth reviewing directly if you want the outline in its original form rather than a summary.

Exam Format, Scoring, and Time Limit

The mechanics of the state portion are simple to state but easy to underestimate:

  • 30 total questions - 25 scored, 5 unscored pretest items mixed in without identification
  • 45 minutes allowed for the entire exam
  • 19 of 25 scored questions correct is the passing threshold
  • All questions are multiple-choice, delivered on a closed-book computer testing platform

Because pretest items aren't flagged, you can't skip questions you assume "don't count." Every item deserves equal attention within your 45-minute window - roughly a minute and a half per question if you pace evenly, though most candidates move faster through recall-based items and slow down on scenario questions. For a full walkthrough of exactly what the passing threshold means for your prep strategy, see TX-PREI Passing Score 2026.

Key Takeaway

With only 25 scored questions and a 19-correct passing line, missing more than six scored items fails you - treat every domain as high-stakes, not just the largest one.

The Five TX-PREI Content Areas

The state outline organizes content into five domains, and the scored-item allocation across them is uneven: 2, 3, 3, 9, and 8 out of 25 scored questions. Licensing Law is the single largest domain by a wide margin, followed closely by General Provisions. That weighting should directly shape how you divide your study time.

Domain 1: Structural Systems - Texas SOP Exclusions and Unique Reporting Requirements

Focuses on where the Texas Standards of Practice diverge from a generic structural inspection scope, and what must (or must not) appear in a Texas inspection report for structural components.

  • Know which structural items are explicitly excluded from SOP-required reporting
  • Understand Texas-specific report language expectations

Domain 2: Electrical Systems - Texas SOP Exclusions and Unique Reporting Requirements

Covers the same exclusions-and-reporting logic applied to electrical systems under Texas rules rather than generic national practice.

  • Identify electrical items outside mandatory SOP inspection scope
  • Recognize Texas-specific documentation requirements

Domain 3: Mechanical Systems - Texas SOP Exclusions and Unique Reporting Requirements

Mirrors the structural and electrical domains but applies to HVAC and other mechanical components as defined by Texas SOP.

  • Distinguish required inspection points from excluded ones
  • Apply correct reporting terminology per Texas SOP

Domain 4: Licensing Law - Chapter 1102, Texas Occupations Code

The largest domain on the exam. Covers the statutory foundation of inspector licensure in Texas - definitions, license categories, prohibited acts, and enforcement authority.

  • Understand TREC's statutory authority under Chapter 1102
  • Know license classifications and what each permits

Domain 5: General Provisions - TREC Rules, Chapter 535, Subchapter R (Real Estate Inspectors)

The second-largest domain. Covers the administrative rules TREC has adopted to implement the statute - application procedures, renewal, CE, and conduct standards.

  • Know Subchapter R's structure and where key rules live
  • Connect rule requirements (fees, CE hours, insurance) back to statute

Because Licensing Law and General Provisions together account for 17 of the 25 scored questions, candidates who under-study these two domains in favor of the three technical-systems domains tend to struggle most. A domain-by-domain breakdown with more detail on exclusions and reporting language is in the TX-PREI Exam Domains 2026 guide.

Eligibility and the Application Path

TX-PREI candidates don't just show up and register - TREC requires a documented path before you're authorized to sit for the state exam. At minimum, applicants must be at least 18 years old, be U.S. citizens or lawfully admitted, satisfy honesty, trustworthiness, and integrity requirements, and complete fingerprints and a background check before receiving TREC authorization.

Beyond the personal eligibility criteria, TREC recognizes two alternative education/experience routes to qualify for the Professional Inspector exam - these are alternatives, not stackable requirements:

  • Substitute-education route: 194 total hours - 154 coursework hours plus a 40-hour practicum
  • Alternative sponsored route: 134 coursework hours, plus 12 months active as a Real Estate Inspector during the preceding 24 months, plus 175 supervised inspections

Once authorized, applicants generally must complete their application within one year, and if the national and state exams are taken separately, the national exam (NHIE) should be completed before the state exam. Passing results are valid for one year. If you fail the state portion three times, TREC requires completion of either the 20-hour Texas Law module or the 24-hour Texas Standards of Practice module before you can be reauthorized to retest. Active licensure also requires maintaining at least $100,000 in per-occurrence professional liability insurance or an equivalent financial responsibility arrangement. A full checklist of these requirements is broken out in TX-PREI Requirements 2026.

Three-Fail Rule: After a third state-portion failure, you can't simply reschedule - TREC requires the 20-hour Texas Law or 24-hour Texas Standards of Practice module first. Budget study time accordingly rather than treating retakes as free attempts.

Fees, Renewal, and Continuing Education

TREC Rule 535.210 sets the base Professional Inspector application fee at $120 and the base timely renewal fee at $60, with separate online-system charges applied on top of those base amounts. Once licensed, renewal happens every two years and requires 32 continuing education hours: 8 non-elective hours covering legal, ethics, standards-of-practice, and report-writing topics, plus 24 elective hours, with a cap of no more than 16 hours in any single subject area. Maintaining the required insurance or financial responsibility is an ongoing condition of active licensure, not a one-time checkbox. For the complete cost picture across application, exam, and renewal cycles, see TX-PREI Certification Cost 2026.

Who Uses This Credential

Passing TX-PREI (alongside the NHIE and meeting TREC's other requirements) is what allows someone to legally operate as a licensed Professional Inspector in Texas - performing pre-purchase home inspections for buyers, sellers, and real estate transactions across the state. Real estate brokerages, independent inspection firms, and self-employed inspectors all rely on this license as the baseline credential for offering inspection services in Texas. If you're weighing whether this career path fits your goals, the earnings landscape is covered in the TX-PREI Salary Guide 2026, and open positions and hiring patterns are discussed in TX-PREI Jobs.

Because the state portion tests Texas-specific law and rule knowledge rather than general inspection technique, it's also the piece employers and clients implicitly trust you've mastered when they see "TREC Licensed Professional Inspector" - it signals you know the legal boundaries of the job, not just the technical ones.

How to Prepare Without Wasting Time

Given the domain weighting, an efficient prep sequence puts the heaviest domains first and treats the three SOP-exclusion domains as a shorter, later pass. A simple structure:

Week 1

Licensing Law (Chapter 1102)

  • Read through the statute's definitions, license categories, and prohibited acts
  • Drill practice questions targeting the 9-question allocation on this domain
Week 2

General Provisions (Rules, Chapter 535, Subchapter R)

  • Map TREC rules to the statute they implement
  • Focus on application, renewal, CE, and conduct-standard rules
Week 3

Structural, Electrical, and Mechanical SOP Exclusions

  • Build a quick-reference list of exclusions per system
  • Practice matching scenarios to correct Texas reporting language
Week 4

Full Timed Review

  • Run full 30-question, 45-minute practice simulations
  • Revisit any domain scoring below your target on missed questions

Spaced repetition of statute and rule terminology tends to work better than one-time memorization, simply because Licensing Law and General Provisions questions often hinge on precise definitions. If you want a condensed reference for last-minute review, the TX-PREI Cheat Sheet 2026 consolidates the must-know facts from all five domains onto one page. For a structured, step-by-step version of this plan, see the TX-PREI Study Guide 2026, and if you're still deciding how much runway to give yourself, How Hard Is the TX-PREI Exam? walks through what makes the state portion challenging relative to its short time limit.

Running full-length, timed practice sets on our practice test platform is one of the fastest ways to find out which domain is actually costing you points versus which one you only feel unsure about. Because the exam gives you just 45 minutes for 30 questions, rehearsing that pace on realistic practice questions matters as much as knowing the material.

Scheduling Reality: Since passing results are valid for only one year and the application itself has a one-year completion window, treat your prep timeline as bounded - don't let study drift past the point where your authorization or scores expire.

Frequently Asked Questions

Is TX-PREI the same exam as the National Home Inspector Examination?

No. TX-PREI refers specifically to the Texas state-portion exam administered for TREC, which is separate from the NHIE. Most candidates need to pass both, and the national exam should be taken first when the two are attempted separately.

How many questions are on the TX-PREI state exam, and how much time do I get?

The exam has 30 multiple-choice questions total - 25 scored and 5 unscored pretest items - with 45 minutes allowed to complete it.

What score do I need to pass the TX-PREI state portion?

You need to answer 19 of the 25 scored questions correctly. Unscored pretest items don't count toward this total, but they're not identified during the exam.

Which domain should I prioritize most heavily?

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. Together they make up more than two-thirds of the scored exam.

What happens if I fail the state exam three times?

After a third failed attempt, TREC requires completion of either the 20-hour Texas Law module or the 24-hour Texas Standards of Practice module before you can be reauthorized to test again.
