In order to join the National Association of Certified Home Inspectors, candidates must pass the Online Inspector Examination and Ethics Obstacle Course. The Online Inspector Examination is free and can be taken at anytime. It contains 120 questions which are different each time the exam is taken. Subject areas include, but are not limited to: roof; exterior; basement, foundation, crawlspace and structure; heating; cooling; plumbing; electrical; fireplace; attic and insulation; and doors, windows, and interiors.
The candidate only has an hour to complete the exam, which contains both true/false and multiple-choice questions. In order to pass, the candidate must answer at least 80% of the questions correctly. The Ethics Obstacle Course is based on information found in the NACHI Code of Ethics. It consists of hypothetical questions which the candidate must answer in order to advance a computer figure toward the finish line. There is no time limit or specific scoring system for this exam; either candidates reach the finish line or they do not.
