What Is the National Home Inspector Examination?
The National Home Inspector Examination, commonly called the NHIE, is a professional competency examination developed and administered by the Examination Board of Professional Home Inspectors.
The exam evaluates whether a candidate can inspect residential properties, identify and analyze observed conditions, communicate findings in an inspection report, and follow the professional responsibilities associated with home inspection work.
Key point: passing the NHIE does not automatically make someone licensed or certified. It is one component of the licensing or credentialing process used by many states and professional associations.
Home Inspector Licensing Requirements
Home inspector regulation is handled primarily at the state level. Some states require candidates to pass the NHIE before applying for a license, while others use different requirements or do not regulate home inspectors through a state licensing program.
Depending on the state, an applicant may also need to complete approved education, supervised inspections, field training, a state-specific examination, a background check, an insurance requirement, or a separate licensing application.
Before Registering
- Determine whether your state regulates home inspectors.
- Confirm whether the NHIE is required for your license or professional credential.
- Review any education or field-training requirements.
- Determine whether state approval is required before scheduling the exam.
- Check whether you must also take a state-specific law or standards examination.
- Verify the testing provider, registration process, fee, and identification requirements for your state.
NHIE Exam Format
The NHIE is a computer-based examination containing 200 multiple-choice questions. Candidates receive four hours to complete the exam.
The pretest questions are mixed throughout the examination and cannot be identified. Answer every question as though it will count toward your score.

NHIE Content Domains
The current NHIE content outline is divided into three performance domains. Most questions involve the inspection of property and building systems.
Property and Building Inspection/Site Review
This is the largest exam domain. It measures whether a candidate can inspect accessible residential components, recognize common conditions and deficiencies, understand how systems operate, and identify situations that require further evaluation.
Property and Building Topics
- Site grading, drainage, walkways, retaining walls, and vegetation
- Exterior wall coverings, flashing, trim, windows, doors, decks, porches, and balconies
- Roof coverings, drainage systems, penetrations, flashings, skylights, and chimneys
- Foundations, framing, floors, walls, columns, beams, and roof structures
- Service entrances, panels, overcurrent protection, grounding, wiring, receptacles, and fixtures
- Water-supply piping, drainage, waste and vent systems, fixtures, and water-heating equipment
- Heating equipment, fuel systems, controls, distribution systems, and venting
- Cooling equipment, controls, condensate management, and distribution systems
- Insulation, vapor control, ventilation, and moisture-management systems
- Interior walls, ceilings, floors, stairs, railings, windows, doors, and installed components
- Fireplaces, chimneys, solid-fuel appliances, and related venting
- Life-safety concerns and installed safety equipment
What Candidates Need to Understand
Questions frequently require more than recognizing the name of a component. Candidates may need to determine whether a component is accessible, identify its normal operating purpose, recognize a common deficiency, understand possible implications, or determine when additional evaluation is appropriate.
A standard home inspection is generally a visual examination of accessible systems and components. It is not the same as a technically exhaustive inspection, engineering analysis, environmental assessment, or municipal code inspection.
Analysis of Findings and Reporting
This domain measures the ability to turn inspection observations into clear, useful, and professionally appropriate conclusions.
Professional Responsibilities
This domain covers the legal, contractual, ethical, and professional obligations involved in providing home inspection services.
Professional Topics to Review
- Purpose and elements of a written preinspection agreement
- Scope, exclusions, limitations, and terms of service
- Contractual responsibilities and limits of liability
- Applicable laws, regulations, and standards of practice
- Negligence and professional duty
- Conflicts of interest
- Inspector financial interests in a property or transaction
- Relationships with clients, agents, contractors, and other parties
- Objectivity, integrity, and confidentiality
- Professional communication and recordkeeping
- Recognition of work that falls outside the inspector’s qualifications or scope
How to Register for the NHIE
Registration procedures depend on the state in which the candidate is testing or seeking licensure. Most candidates register through the examination provider identified for their state.
Exam registration and state licensing are separate processes. After passing, candidates must still complete the application and documentation required by the appropriate state agency or professional organization.
What to Expect on Test Day
Test-Day Checklist
- Review the appointment confirmation and testing-center address.
- Arrive at the time specified by the testing provider.
- Bring every required form of identification.
- Make sure the name on your identification matches your registration.
- Leave unauthorized notes, books, electronics, and personal items outside the testing room.
- Do not assume that personal calculators or reference materials are permitted.
- Complete the computer tutorial before beginning the timed examination.
- Read each question carefully and select the best answer.
- Monitor your pace throughout the four-hour testing period.
- Answer every question before submitting the examination.
NHIE Scores
NHIE results are reported on a scaled range from 200 to 800. A scaled score of at least 500 is required to pass.
Scaled scoring allows different versions of the examination to be reported on the same score range. A score of 500 does not necessarily mean that exactly 62.5% of the questions were answered correctly.
Retaking the NHIE
Candidates who do not pass may take the examination again after completing the required waiting period.
Home Inspector Sample Practice Questions
The following original questions review several skills measured by the NHIE. They are not official Examination Board of Professional Home Inspectors questions.
1. An inspector observes that the ground beside a foundation slopes toward the house. Moisture staining is also visible on the basement wall. What is the most appropriate report recommendation?
- State that the foundation will fail within one year
- Recommend improving drainage and having the moisture condition evaluated
- Report that no action is necessary unless water is actively flowing
- Recommend replacing the entire foundation
Show Answer and Explanation
Answer: B. Recommend improving drainage and having the moisture condition evaluated
Grading that directs water toward the building can contribute to moisture intrusion. The inspector should report the observed conditions and recommend an appropriate corrective response without predicting unsupported structural failure.
2. A roof cannot be safely walked because it is wet and steep. What should the inspector do?
- Walk the roof because every roof must be inspected from its surface
- Exclude the roof entirely without mentioning it in the report
- Inspect it from safe accessible locations and report the limitation
- Ask the client to sign a waiver requiring the inspector to walk it
Show Answer and Explanation
Answer: C. Inspect it from safe accessible locations and report the limitation
The inspector should not create an unreasonable safety risk. The report should identify the inspection method and clearly describe any limitation.
3. An inspector observes water staining below a roof penetration but cannot determine whether the area is currently leaking. Which report language is most appropriate?
- “The roof is definitely leaking and must be replaced.”
- “Water staining was observed below the penetration; further evaluation is recommended.”
- “The staining is cosmetic and can be ignored.”
- “The seller is responsible for repairing the roof.”
Show Answer and Explanation
Answer: B. “Water staining was observed below the penetration; further evaluation is recommended.”
This statement objectively describes the visible condition and recommends additional evaluation without claiming facts that were not established during the inspection.
4. When should a written preinspection agreement generally be completed?
- After the inspection report has been delivered
- Before the inspection begins
- Only when a material defect is discovered
- After the property transaction closes
Show Answer and Explanation
Answer: B. Before the inspection begins
The agreement establishes the scope, limitations, terms, and responsibilities of the inspector and client before the service is performed.
How to Prepare for the Home Inspector Exam
Effective preparation requires more than memorizing isolated definitions. Candidates should understand how residential systems operate, how deficiencies affect other components, and how findings should be communicated.
