1.1 Current NHIE Exam Facts

What the NHIE Is and Who Owns It

The National Home Inspector Examination (NHIE) is the national competency exam for home inspectors in the United States and Canada. It is owned and maintained by the Examination Board of Professional Home Inspectors (EBPHI), an independent not-for-profit corporation founded in 1999. EBPHI's stated mission is "to establish the standard of competence for home inspectors and to enhance consumer confidence in home inspection professionals." EBPHI is not a training school and does not teach the material — it builds, validates, and defends the exam, then licenses it to PSI (and a few state-contracted vendors) for delivery.

The exam is administered by PSI through a network of computer-based testing centers — more than 300 sites across the U.S. and Canada, with testing typically available six days a week. A handful of jurisdictions require you to register through a state-contracted administrator rather than directly: candidates seeking licensure in Florida, Illinois, Nevada, Oklahoma, South Dakota, Texas, Tennessee, Vermont, and Washington must take the NHIE through those states' contracted channels. Confirm your state's pathway before paying.

Question Format and Scoring

Every NHIE item is a single-best-answer multiple-choice question with four options (A-D). EBPHI is explicit that some distractors are partially correct — the instruction is always to select the BEST answer, not merely a defensible one. That is a deliberate design choice: it tests whether you can rank a complete, in-scope, standards-aligned action above a half-right one.

Of the 200 questions, 25 are "pretest" items seeded randomly throughout the exam. EBPHI uses them to gather statistics on new questions before they ever count toward a score; they keep the bank reliable, valid, and legally defensible. You are not told which items are unscored, so you must answer all 200 with the same care. Effectively you are graded on 175 scored items.

Scoring is criterion-referenced, not curved against other test-takers. Your raw score (number of scored items correct) is converted to a scaled score on a 200-800 range, and the passing cut is 500. The cut is set by subject-matter experts using a formal standard-setting study, so it represents a fixed minimum competency rather than a fixed percentage. A practical consequence: every passing score signals the same competency — a 510 and a 720 both simply mean "passed." Do not chase a high margin; chase the cut reliably across all domains.

Logistics, Fees, and Recognition

The standard fee is $225 per attempt in most U.S. states and Canada. It is non-refundable and non-transferable, it applies to every registration (first attempt or retake alike), and it is forfeited if you do not sit within one year of the date PSI receives payment. You may retake the exam as many times as needed, but must wait at least 30 days between attempts. PSI also sells an optional online practice exam (about $50 per session) that mirrors the format but is not a study substitute.

The NHIE is recognized in 35+ states and Canadian provinces for home-inspector licensing and is required or accepted for membership in associations such as ASHI and several Canadian inspector bodies. Because it is the de facto national standard, passing it often satisfies the testing component of licensure in multiple jurisdictions at once — but licensing also layers on state-specific education, experience, or background requirements that the exam itself does not cover.

• Owner: EBPHI (builds and defends the exam)
• Vendor: PSI (delivers it; some states use their own)
• Cut: scaled 500 on a 200-800 scale, criterion-referenced
• Money rule: $225, non-refundable, expires one year after payment

Why the Exam Is Designed This Way

EBPHI builds the NHIE to accepted psychometric standards for a "high-stakes" public-protection examination, the kind of rigor promulgated by bodies such as AERA, the National Commission for Certifying Agencies (NCCA), the APA, and the EEOC. That matters to you because it explains the exam's behavior: the content is tied to a documented role delineation study, the pretest items keep new questions statistically defensible before they count, and the cut score is justified by a formal standard-setting study rather than picked arbitrarily.

You are taking a legally defensible licensing instrument, and the questions are written to discriminate between minimally competent inspectors and those not yet ready to protect a buyer.

A second design consequence is scope discipline. Because the exam protects the public, it rewards answers that stay inside the inspector's defined role — observe, describe, and recommend further evaluation — and penalizes answers that wander into definitive diagnosis, repair pricing, or product specification. When two options both seem technically plausible, the better answer is almost always the one that is more complete and stays within the standards of practice. Treat "what is the inspector allowed to do here?" as a question you ask of every item.

Treat Official Sources as the Authority

Because policies, fees, and the content outline can be revised between role-delineation cycles, always confirm the current details against EBPHI's own materials (homeinspectionexam.org) and PSI's candidate bulletin before relying on a secondary summary. Use this section's facts as the working baseline — owner, vendor, 200 items, 175 scored, 4 hours, scaled 200-800, cut 500, $225 — and verify anything affecting your money or eligibility (fees, the one-year fee window, retake timing, your state's registration channel) directly from the source closest to the policy.
