How to study for the NHIE
Study for the NHIE by following EBPHI's content outline, which puts 70% of the exam on building systems and 30% on reporting and professional practice. Read from the sources the exam is referenced to, then test yourself at full length and fix the tasks you miss.

Start with the outline
EBPHI tells candidates to compare any course they're thinking about to the NHIE content outline. The outline lists 19 tasks in three domains, with a weight on each. It's the closest thing to a table of contents for the exam.
For every task and its weight, see NHIE domain weights.
Read what the exam is referenced to
EBPHI says every question traces to a published source or to the agreement of its subject matter experts. It lists these references:
| Reference | Edition |
|---|---|
| NHIE Mechanical Systems and NHIE Content Manual | 2019 |
| NHIE Structural Systems and Business Manual | 2019 |
| International Residential Code (IRC) | 2021 |
| NFPA 101, Life Safety Code | 2021 |
| NFPA 70, National Electrical Code (NEC) | 2023 |
The two NHIE manuals are written for the exam, so start there. Use the codes to look up what the manuals point to. EBPHI notes the list doesn't mean you have to study all of these, or only these.
Split your hours by weight
For every 10 hours of study, give about 7 to Domain 1, 2 to Domain 2, and 1 to Domain 3. Inside Domain 1, no system is small enough to skip.
| Domain | Weight | Hours out of every 10 |
|---|---|---|
| 1. Property and Building Inspection / Site Review | 70% | 7 |
| 2. Analysis of Findings and Reporting | 20% | 2 |
| 3. Professional Responsibilities | 10% | 1 |
Domains 2 and 3 are about writing a report and running the job ethically. They don't feel like inspecting, and they're still 30% of your score.
Practice at full length
The real exam is 200 questions in 4 hours, about 72 seconds each, with no calculator. Take at least one practice exam at that length before test day, so the pace and the fatigue aren't new.
EBPHI sells its own practice quizzes. The Whole House quiz has 50 questions and the others have 25, and each purchase can be taken once. It no longer offers a free online sample test.
Study your misses by task
After a practice exam, sort what you missed by outline task. Three misses in one task point to a gap. Three misses spread across three tasks might be bad luck.
Then go back to the source for the weak tasks and test again. If you've already sat the NHIE and failed, the content-area graph on your score report is the place to start. For more about that, see failed the NHIE.
Answer every question
You pass by answering enough questions correctly, so a blank is the same as a wrong answer. EBPHI's own advice for the exam, in short:
- Read the question before you look at the options.
- Come up with the answer in your head first.
- Cross out the options you know are wrong, then read the rest.
- Don't change an answer unless you misread the question.
