The National Home Inspector Examination (NHIE) provides home
inspectors a recognized certification which speaks to their skill and expertise
for certification. 31 states require the NHIE for licensing, and some
associations require the exam to obtain membership.
This article discusses the certification exam for the 31
states that require the NHIE.
To sit for the National Home Inspector examination, a
candidate needs a high school diploma or equivalent, possess basic soft skills
(customer service), and have mechanical aptitude. Some states may require
additional education beyond high school and some form of on-the-job-training in
building inspection, home inspection, construction, drafting, or engineering.
The application varies from state-to-state but includes
providing proof of eligibility and payment of licensing fees.
Purpose and content
of the NHIE examination
The scope of the NHIE is to assess a candidate’s knowledge
and ability to perform home inspections. The purpose of a home inspector is to
ensure a commercial building or residence meets local, state, and federal
The first domain of the examination assesses a candidate’s
ability to properly perform the duties of a home assessor. The foundational
skills required are site conditions, building components (inside and out),
electrical, structural systems (walls, roof, and support), heating,
ventilation, and plumbing. In addition, knowledge of insulation, flood plans,
and before and aftermarket fixtures is required.
A home inspector has the general knowledge of everything in
the building – from the cement that is poured for the floor to the after-market
addition of ceiling fixtures and fences. While you do not need to know how to
fix the water pipes so they don’t leak, you have to be able to identify that
they are incorrect and suggest the correction. A home inspector is a
jack-of-all-trades and serves the client by ensuring the building is safe and
The second domain focuses on your ability to follow the rules
and regulations governing contracts for inspection and performing home
inspector duties within your state with integrity, quality, and objectivity
while protecting the client’s interests.
As a home inspector, you will be expected to write valid
inspection contracts and reports while maintaining objectivity to the building
being inspected. The onus is on the home inspector to be thorough and fair,
ensuring the safety of the public and client are maintained with an accurate
assessment of the home.
The NHIE is divided into two performance domains, Building
Science, Analysis and Reporting, and Business Operations. There are 200
multiple-choice questions, of which 25 questions are un-scored and are included
to measure potential adjustments to the examination. You will have four hours
to complete the exam.
The content of the NHIE is as follows:
