NHIE exam guide

The National Home Inspector Examination, or NHIE, is the competency exam produced by the Examination Board of Professional Home Inspectors. EBPHI states that the exam has 200 multiple-choice questions, including 25 unscored pretest items, and that you have four hours to finish it. Passing it does not by itself license you in every state.

Format details below come from EBPHI’s FAQ and its exam overview packet (updated June 25, 2024). Confirm the current bulletin when you register. Your state can add rules the national packet does not list.

Who writes it, and who uses it

EBPHI is an independent nonprofit, founded in 1999. Its stated mission is to establish the standard of competence for home inspectors and to enhance consumer confidence in the profession. It is not a membership association. The FAQ explains that the exam is not built on one association’s standard of practice, because those standards belong to the associations.

The same FAQ says the NHIE is used in 35 states and several Canadian provinces for home inspector regulation. “Used for regulation” is not the same sentence as “required for you.” Passing does not let you work everywhere. EBPHI says regulatory bodies have additional requirements, and that you must check the body in any state where you intend to inspect.

The FAQ also says the exam is a membership requirement for the American Society of Home Inspectors and several other organizations. ASHI’s own levels of membership page is more specific: the NHIE is required for the Inspector level when your state does not license home inspectors, and it is part of the ASHI Certified Inspector credential. Associate membership, on that page, does not list the NHIE. Read both pages before you book a seat for a logo.

The full path around the exam—training, the application, insurance—is in how to become a home inspector.

Format, score, and time

The 25 pretest questions are spread through the exam, and the overview packet says the four-hour clock starts when you see the first question.

Scoring is scaled from 200 to 800. The passing scaled score is 500. Candidates are not graded on a curve. EBPHI says a score above passing is not a sign of more advanced knowledge or a prediction of better job performance. Everyone who meets the pass point has shown an acceptable level. In the United States you receive a score report before you leave the testing center. What that report shows—a number, or only pass/fail—depends on the state and the center.

The overview packet’s content outline, based on its role-delineation study, splits the exam into three domains: property and building inspection / site review (70%), analysis of findings and reporting (20%), and professional responsibilities (10%). The FAQ’s topic list under those domains includes inspection methods, reporting, building systems (exterior, structure, roof, electrical, heating and cooling, insulation and ventilation, plumbing, interior, fireplace and chimney), and professional practice. The packet says the outline is not a complete list of every topic or every skill a competent inspection needs.

How your state may change the sitting

The FAQ says that if you are seeking licensing in Florida, Illinois, Nevada, Oklahoma, South Dakota, Tennessee, or Washington, you must take the NHIE through that state’s contracted test administrator. That is an administration rule, not a complete list of states that require the exam.

The overview packet also describes state-specific arrangements, including Texas and Vermont, and says Illinois, South Dakota, and Washington add state-specific questions. Fees, names on the registration screen, and whether you need preapproval can differ. The FAQ lists the fee as $225 per test in most states and in Canada, and says to confirm when you register. The packet says fees are nonrefundable, nontransferable, and subject to change.

If you do not pass, the FAQ says you wait 30 days before a retake. That wait is the standard for this exam unless a law or regulation requires otherwise. Each attempt has its own fee. The packet says you may retake as many times as you wish unless your state says otherwise.

How to study

EBPHI does not review or endorse training companies. It tells candidates to compare any curriculum to the content outline. It says every question is referenced to a published source or based on the consensus of subject-matter experts, and that studying the reference list is not a statement that those sources alone are enough.

References named on the FAQ: the National Home Inspector Examination Mechanical Systems and NHIE Content Manual (2019), the Structural Systems and Business Manual (2019), the International Residential Code for One- and Two-Family Dwellings (2021), NFPA 101 Life Safety Code Handbook (2021), and NFPA 70 National Electrical Code (2023). EBPHI sells its manuals and practice quizzes. The FAQ says the Whole House quiz is 50 questions, other quizzes are 25, a purchased quiz may be taken once, and there is no longer an online sample test.

Use the outline as the checklist. If a school’s practice tests never mention reporting limitations or a written agreement, you have a gap: those topics sit in the packet’s second and third domains. The FAQ’s own note to people who did not pass is that some candidates rely on a trainer’s exams and have not reviewed the outline. Do that review before you sit.

If you need a testing accommodation, the overview packet says to request it from the test administrator in advance and to include supporting documentation. Do not wait until the morning of the exam.

After you pass

The score report is yours. EBPHI says it is not sent automatically to your licensing agency. You submit it, with whatever else the board asks for: application, background check, fees, proof of education, insurance. Until that agency says you may inspect for a fee, a passing score is not a license.

If you pass and you are eligible for GI Bill education benefits, the FAQ says you may be eligible for reimbursement. It names VA form VBA-22-0803-ARE, plus a copy of the paid receipt and the exam results. Ask the Department of Veterans Affairs whether you qualify. This page cannot.

Then set up the work you are actually allowed to do. Insurance, agreements, and first clients are in how to start a home inspection business. When you are choosing a place to write the report, see the inspection software guide. You remain the inspector of record.
