National Home Inspector Exam (NHIE): How to Pass It
The National Home Inspector Exam explained: 200 questions in four hours, the $225 fee and state exceptions, scaled scoring, retakes, and how to study for it.
Short answer: The National Home Inspector Examination (NHIE) is a four-hour, 200-question multiple-choice exam run by the Examination Board of Professional Home Inspectors (EBPHI). 175 questions are scored, the pass mark is 500 on a 200 to 800 scale, and the fee is $225 in most states. You can retake it after 30 days. Study from EBPHI's content outline, not from memory of an association's standard of practice.
For most people becoming a home inspector, the NHIE is the one exam that stands between the course and the license. EBPHI says it is used for licensing in 35 states. It is also a membership requirement for some association credentials, including ASHI Certified Inspector.
Everything on this page comes from EBPHI's own pages or from state regulators, as of September 2026. Where your state's rules differ from EBPHI's general policy, the state wins.

What the exam covers
EBPHI bases the exam on a formal study that defines competent practice, which it calls a Role Delineation Study. It runs one every five years, and the last was in 2022. The exam tests three performance domains:
- Property and Building Inspection/Site Review
- Analysis of Findings and Reporting
- Professional Responsibilities
Within those domains, EBPHI's FAQ lists inspection methods, reporting, professional practice and the building systems: exterior, structural, roofing, electrical, heating and cooling, insulating and ventilating, plumbing, interior, and fireplace and chimney.
The exam is not built on any one association's standard of practice. EBPHI says each question is referenced to a published source or to the consensus of subject matter experts. So knowing InterNACHI's or ASHI's standard by heart does not mean you are ready. Download the content outline and use it as your checklist.
Fees, vendors and state exceptions
The standard fee is $225. EBPHI's Test Policies page names five states where the cost is different, and links to each state's own registration page for the amount. Some states also require you to test through their own contracted administrator.
| Situation | States | What to do |
|---|---|---|
| Standard $225 fee through PSI | Most states | Register through EBPHI's registration page or PSI at (855) 807-3992 |
| Different fee | Texas, Oklahoma, Illinois, South Dakota, Washington State | Use the state link on EBPHI's Test Policies page for the current fee |
| Must use the state's contracted test administrator | Florida, Illinois, Nevada, Oklahoma, South Dakota, Tennessee, Washington State | Register through that state's administrator |
| Pearson VUE instead of PSI | Florida, Nevada, Texas | Register with Pearson VUE |
Fees are non-refundable, non-transferable and subject to change. Payment is due when you register, not at the test center. Eligible veterans may be able to get the fee reimbursed under the GI Bill using VA form VBA-22-0803.
Registering and test day
Registration with PSI runs through EBPHI's registration page, where you choose your state and follow its link. You can also call PSI. EBPHI says the exam is available whenever a test center is open and has seats, and most centers are open six days a week. You need to register in advance.
Plan around these policies:
- Cancelling. Tell PSI at least four business days before the exam to change or cancel without penalty. Later cancellations and no-shows pay the full fee.
- Arriving. EBPHI suggests arriving at least 15 minutes early. If you are late, you lose your slot and owe the fee.
- What to bring. Your confirmation number, two forms of signature ID (one with a photo), and your failing score report if you are retaking.
- In the room. No phones, bags, notes or calculators. No food or drink. The tutorial at the start does not count against your four hours.
- Accommodations. Request special arrangements at least 15 business days before your test date, with supporting documentation.
How scoring works
The NHIE is scale scored from 200 to 800, and 500 is the pass point. You are not graded on a curve and you do not compete with other candidates. A panel of subject matter experts sets the passing point for each version of the exam under a psychometrician's guidance, based on how hard each question is. Scaling puts every version on the same 200 to 800 scale.
A higher score does not mean more than a pass. EBPHI says everyone who passes has shown an acceptable level of knowledge, whatever their score.
In the US, you leave the test center with your official score report. It may show your scaled score or only PASS or FAIL. In most states, a failing report shows a graph of your performance in each content area, which tells you what to study for the retake.
Your score does not go to the state automatically. Sending it to your regulator is your job.
EBPHI does not publish a pass rate on the pages we read.
Retakes
You can retake the NHIE as many times as you want, unless your state sets a limit. You must wait 30 days between attempts and pay a new fee each time. Bring your failing score report.
Check your state's rules too. Texas, for example, requires additional education after three failed attempts at its license exam, which has national and state portions.
Which states use the NHIE
EBPHI says the NHIE is used for licensing in 35 states. Its state pages name the NHIE, alone or as one option, for 34 states. They are EBPHI's summaries, not the law. Where the regulator's own page names the NHIE, we list it below. Where only EBPHI does, we say so.
| Group | States (as of September 2026) |
|---|---|
| Regulator or statute names the NHIE as required or accepted | Alabama, Alaska (Existing Homes), Arizona, Arkansas, Connecticut, Delaware, Florida, Indiana, Louisiana, Maryland, Massachusetts, Mississippi, New Hampshire, New Jersey, New Mexico (or the InterNACHI exam), New York, Ohio, Oregon, South Carolina, Tennessee, Vermont, Virginia, West Virginia, Wisconsin |
| Regulator describes a national, state or board-approved exam; EBPHI (and in Illinois and Texas, the test vendor's handbook) identifies it as the NHIE | Illinois, Kentucky, Nevada, Oklahoma, Rhode Island, South Dakota, Texas, Washington |
| Law accepts an exam from EBPHI among others | North Dakota (ASHI, InterNACHI, EBPHI or ICC) |
| Association route, exam must be "psychometrically sound" | Iowa (EBPHI lists Iowa) |
| Does not use the NHIE for the state credential | North Carolina (own board exam, 70% to pass); Montana, Nebraska and Utah (no state exam; Montana is covered below) |
A few details matter state by state. New York accepts either its own exam or the NHIE. Wisconsin adds a state statutes and rules exam. Alabama requires the NHIE plus an ASHI Standards and Ethics exam. Some states limit how old your result can be: Alabama accepts results from within 18 months before you apply, Arizona and Ohio within two years, Mississippi and South Carolina within three years, and Tennessee treats scores as valid for five years. See our license requirements guide for the full state picture.
Montana's 2026 change
Montana began licensing home inspectors on January 1, 2026. Under the old registration, passing the NHIE could stand in for the 40 hours of instruction. The Department of Labor & Industry now says new applicants "can no longer use passage of the National Home Inspector Examination as a valid alternative to the 40 hours" of instruction. If you are applying in Montana, plan on the course.
In states with no license
The NHIE still has uses where the state does not license inspectors. EBPHI says it is a membership requirement for several associations. At ASHI, the ASHI Certified Inspector level requires the NHIE and 250 fee-paid inspections, and the ASHI Inspector level requires it in states without licensing.
How to study for the NHIE
EBPHI does not review or endorse training programs, and it has no free online sample test. It sells two study manuals (Mechanical Systems and NHIE Content Manual; Structural Systems and Business Manual, both 2019) and five practice quizzes. The Whole House quiz has 50 questions and the others have 25. Each purchase can be taken once. EBPHI also lists the 2021 International Residential Code, the 2021 NFPA 101 Life Safety Code Handbook and the 2023 National Electrical Code as helpful references.
A practical approach:
| Phase | What to do |
|---|---|
| Map | Download the content outline. Mark each topic strong, weak or unknown |
| Learn | Work through your pre-licensing course, spending extra time on the weak and unknown topics |
| Connect | Tie each system to what you saw in the field. Questions ask what a finding means, not only what a part is called |
| Report | Practice writing findings. Analysis of Findings and Reporting is a full domain |
| Test | Take practice quizzes under time pressure. Four hours for 200 questions is about 72 seconds each |
| Review | Study every miss until you can explain why the right answer is right |
EBPHI's own test-taking advice is worth following: read the question before the answers, form your answer before you look, eliminate the options you know are wrong, and read every choice before you pick one.
Field experience helps more than cramming. The Analysis of Findings and Reporting domain rewards people who have seen defects and written them up. If you want practice writing findings in a real report, Binsr's library of 12,000+ comments and templates written by inspectors shows how experienced inspectors phrase common defects. Our guide on writing defect comments that hold up covers the same skill.
After you pass
Send your score report to your regulator with the rest of your application. The exam is one requirement among several: EBPHI itself notes that passing does not let you work anywhere in the US right away, because each state has its own requirements. Next come the license application, insurance and your first clients. Our pillar guide on how to become a home inspector covers every step.
