About this exam

The National Home Inspector Examination® (NHIE) is a national, high-stakes licensing-style examination for the home inspection profession, governed and administered by the Examination Board of Professional Home Inspectors (EBPHI). EBPHI describes the NHIE as "the Original Exam for the Home Inspection Profession," and states that by requiring inspectors to pass it, states participate in a national standard for the professional home inspector. The exam is written to address the core competencies of home inspection as they apply in all states, which is why it can serve regulated states with different licensing requirements. It is intended for candidates entering the profession, inspectors seeking licensure where their state mandates an exam, and inspectors who want an independent, nationally recognized measure of competence. Because the content is drawn from practice across structural, mechanical, electrical, plumbing, roofing, exterior and site, interior, insulation and ventilation, and professional practice, preparation should be broad rather than specialty-focused. EBPHI publishes a content outline, practice quizzes, videos, state regulation information, and two study manuals - the Mechanical and Content Manual and the Structural and Business Manual - plus a large reference volume for exam candidates. Always confirm your own state's requirements, since regulation varies by jurisdiction. This page is independent study material and is not affiliated with or endorsed by EBPHI.

What you'll study

Common questions

About NHIE preparation

Who administers the National Home Inspector Examination?

The Examination Board of Professional Home Inspectors (EBPHI) governs and administers the NHIE. EBPHI states that it does so specifically to support the regulatory needs of states in identifying the required level of competence to conduct a quality home inspection.

Do I have to take the NHIE to become a home inspector?

It depends on where you work. EBPHI says that by requiring home inspectors to pass the NHIE, states participate in the national standard for the professional home inspector. Check your state's regulations, since requirements differ between regulated and unregulated jurisdictions.

What topics does the exam cover?

EBPHI states the NHIE addresses the core competencies of home inspection as they apply in all states. That spans the major systems and components of a house plus professional practice topics. Download the official content outline from EBPHI before you build a study plan.

How many questions are on the exam, and how long is it?

EBPHI's public site does not publish the item count or time limit in the material reviewed here, so treat any specific number you see elsewhere with suspicion. Confirm format, length, and appointment details directly with EBPHI or your state agency before scheduling.

What score do I need to pass, and what does the exam cost?

Passing scores and fees are not stated in EBPHI's public overview material. Rather than rely on secondhand figures, verify the current passing standard, fee, and any state-specific rules through EBPHI or the licensing board that requires the exam of you.

What happens if I fail - can I retake it?

Retake rules are set by EBPHI and, in regulated states, by the state agency, and they are not published in the overview material reviewed here. Ask EBPHI or your state board about waiting periods, fees, and any limit on attempts before you sit for the exam.

What study materials does EBPHI recommend?

EBPHI lists a content outline, practice quizzes, videos, state regulation references, and two manuals: the Mechanical and Content Manual and the Structural and Business Manual. EBPHI also offers a reference volume of over 900 pages of home inspection material for the exam and beyond.

In what order should I study?

Start with the content outline so your effort matches the actual blueprint, then work the two manuals by domain, and finish with practice quizzes to expose weak areas. Use the videos for topics that are hard to visualize, and revisit the outline at the end to confirm coverage.

Why do capable inspectors still fail?

The most common cause is studying by general experience instead of the published blueprint, which leaves whole domains - often business, standards, or report writing - underprepared. Others skip practice questions and never test recall under exam conditions. Cover every outline domain, even the ones you rarely encounter in the field.

How do I register for the exam?

EBPHI's site directs candidates to register for the exam online. Before registering, confirm whether your state requires the NHIE and whether any additional state paperwork, pre-licensing coursework, or approval must be completed first.
