- The state exam has 30 questions (25 scored, 5 pretest) with 45 minutes and a 19-of-25 passing threshold.
- Licensing Law (Chapter 1102) is the largest scored domain at 9 of 25 questions.
- Take the National Home Inspector Examination before the TREC state portion when testing separately.
- Base application fee is $120; timely renewal base fee is $60, per TREC Rule 535.210.
Exam Snapshot: Format, Timing, Passing Score
The Texas Professional Real Estate Inspector Exam (TREC State Portion) is a closed-book, computer-based test administered at Pearson VUE test centers on behalf of the Texas Real Estate Commission (TREC). It is deliberately narrow in scope: it covers only the Texas-specific state portion of licensure, not the national content evaluated by the separate National Home Inspector Examination (NHIE). If you're still mapping out how this state exam fits into the bigger licensing picture, the TX-PREI Requirements 2026 guide lays out the full sequence.
Here's the format in plain numbers:
- 30 total questions - 25 scored, 5 unscored pretest items mixed in without identification
- 45 minutes allowed for the entire session
- 19 of 25 scored questions correct required to pass
Because pretest items are indistinguishable from scored ones, every question deserves full attention - there's no reliable way to identify and skip the unscored five.

Scored-Item Domain Breakdown
TREC's outline (effective September 2, 2014, and still linked from Pearson VUE's inspector testing page) allocates the 25 scored questions across five domains. The distribution is uneven, and understanding exactly where the weight sits should shape every hour of your prep.
| Domain | Scored Questions |
|---|---|
| Structural Systems: Texas SOP Exclusions and Unique Reporting Requirements | 2 |
| Electrical Systems: Texas SOP Exclusions and Unique Reporting Requirements | 3 |
| Mechanical Systems: Texas SOP Exclusions and Unique Reporting Requirements | 3 |
| Licensing Law: Chapter 1102, Texas Occupations Code | 9 |
| General Provisions: TREC Rules, Chapter 535, Subchapter R | 8 |
Licensing Law and General Provisions together account for 17 of the 25 scored items - more than two-thirds of the exam. That means a candidate who is excellent at inspecting homes but weak on statute and rule citations is at serious risk of failing the state portion even after passing the NHIE. A full walkthrough of each content area, including the reasoning behind these weights, is available in the TX-PREI Exam Domains 2026 guide.
Key Takeaway
Spend the majority of your study hours on Licensing Law and General Provisions - together they outweigh all three technical-systems domains combined.
What Each Domain Actually Tests
Structural Systems: Texas SOP Exclusions and Unique Reporting Requirements
This domain isn't about how to inspect a foundation - it's about what Texas Standards of Practice explicitly excludes from the structural scope and how findings must be worded in the report.
- Know which structural components are outside the mandatory inspection scope under Texas SOP
Electrical Systems: Texas SOP Exclusions and Unique Reporting Requirements
Expect questions on reporting language specific to Texas rules rather than general electrical theory.
- Distinguish standard reporting requirements from Texas-specific exclusions and disclosures
Mechanical Systems: Texas SOP Exclusions and Unique Reporting Requirements
Same pattern as structural and electrical - the exam checks whether you know the Texas carve-outs, not generic HVAC or plumbing mechanics.
- Memorize which mechanical items fall outside mandatory reporting under Texas SOP
Licensing Law: Chapter 1102, Texas Occupations Code
The heaviest-weighted domain. This tests statutory knowledge: licensing categories, disciplinary authority, and the legal framework governing inspector conduct in Texas.
- Read Chapter 1102 directly rather than relying only on secondary summaries
General Provisions: TREC Rules, Chapter 535, Subchapter R
This domain covers the administrative rules TREC has built around the statute - application processes, insurance requirements, and inspector conduct rules found in Subchapter R.
- Cross-reference rule numbers with the practical scenarios they govern

Eligibility, Routes, and Fees
Before you can even schedule the state exam, TREC requires you to meet baseline eligibility and choose an education pathway. These are non-negotiable gates, not suggestions.
- Be at least 18 years old and a U.S. citizen or lawfully admitted alien
- Satisfy honesty, trustworthiness, and integrity requirements
- Complete fingerprinting and a background check
- Receive formal TREC authorization before testing
There are two separate education routes to Professional Inspector eligibility - they 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
On fees, TREC Rule 535.210 sets the numbers plainly: a $120 base application fee for the Professional Inspector license and a $60 base timely renewal fee, with separate online-system charges layered on top depending on how you submit. For the complete cost picture across education, application, and renewal, see TX-PREI Certification Cost 2026: Complete Pricing Breakdown.
Once authorized, you must complete your application within one year, and if you're testing the national and state portions separately, take the NHIE before the state exam - not the reverse. Passing results on either exam remain valid for one year, so sequence your testing dates carefully around the TX-PREI Exam Dates 2026 scheduling guide.
Test-Day Logistics with Pearson VUE
The state exam is closed-book and computer-administered at a Pearson VUE test center. A few procedural details trip up candidates who assume it works like other licensing exams:
- Bring two unexpired signature IDs, one of which must be a primary government-issued photo ID
- Names on both IDs must match your test registration exactly
- Calculators are permitted only if they do not support alphabetic characters - leave programmable or text-capable models at home
Key Takeaway
Double-check your registration name against your ID well before test day. A mismatch at check-in can cost you the appointment and the fee.
Licensure, Renewal, and CE Rules
Passing the exam is only part of staying licensed. Active Professional Inspector licensure requires at least $100,000 per-occurrence professional liability insurance or equivalent qualifying financial responsibility, maintained continuously - not just at application.
Renewal happens every two years and requires 32 continuing education hours, broken into:
- 8 non-elective hours covering legal updates, ethics, standards-of-practice, and report-writing
- 24 elective hours, with no more than 16 hours in any single subject area
And if the state portion gives you trouble more than once: after three failed attempts, TREC requires completion of either the 20-hour Texas Law module or the 24-hour Texas Standards of Practice module before you're reauthorized to retest. That's a strong incentive to prepare thoroughly the first time rather than treat the exam as low-stakes.

Final-Week Review Plan
Given the 45-minute time limit and the domain weighting shown above, your last week before test day should mirror the exam's own priorities rather than spreading effort evenly across all five domains.
Licensing Law (Chapter 1102)
- Read the statute directly, focusing on licensing categories and disciplinary provisions
- Drill scenario questions tied to the 9-question weight
General Provisions (Rule 535, Subchapter R)
- Match rule numbers to real application and conduct scenarios
- Review insurance and renewal rule details, since these overlap with practical licensure
SOP Exclusions Across Structural, Electrical, Mechanical
- Build a quick-reference list of what each system domain excludes from mandatory reporting
- Time yourself on mixed question sets to simulate the 1.5-minute-per-question pace
Full Simulation and Gaps
- Run a full 30-question timed simulation on our practice test platform
- Revisit only the domains where you missed items, prioritizing Licensing Law and General Provisions
This weighting-driven approach - not a generic weekly template - is the core method described in more depth in the TX-PREI Study Guide 2026. Combine timed drills from the main practice test site with direct statute reading, since memorized rule numbers without context tend to fall apart under exam-style scenario questions.
FAQ
There are 30 total questions - 25 scored and 5 unscored pretest items. You need 19 of the 25 scored questions correct to pass, meaning you can miss up to 6 scored items.
Licensing Law: Chapter 1102, Texas Occupations Code carries the most weight at 9 of 25 scored questions, followed closely by General Provisions (TREC Rules, Chapter 535, Subchapter R) at 8. Together these two domains make up more than two-thirds of your score.
When testing the two portions separately, TREC requires you to take the National Home Inspector Examination (NHIE) before the TREC state portion. Passing results on either exam remain valid for one year.
After three failed attempts, you must complete either the 20-hour Texas Law module or the 24-hour Texas Standards of Practice module before TREC will reauthorize you to retest.
Under TREC Rule 535.210, the base Professional Inspector application fee is $120 and the base timely renewal fee is $60; online-system charges apply separately on top of these base amounts.
