Exam overview

This exam consists of 120 questions that are randomly generated from a much larger (and constantly evolving/expanding) pool of questions. This means that each time you take the exam it will be completely unique (there are over 1,000,000,000 versions of the exam). You will have 60 minutes to complete all 120 questions. The passing cut-off score is 80.

How the exam is scored

The exam uses a weighted scoring system. Each of the 120 questions is weighted based on importance. Questions that have safety implications or cover larger issues count more than questions that have less serious implications or are geographically regional. Not only are the questions weighted, the answers are as well in the sense that an exam taker is punished severely (in terms of score) for incorrectly answering questions that indicate that he/she could cause physical harm to the public, but not greatly rewarded (in terms of score) for correctly answering such questions. Likewise, difficult questions (questions that lie outside or nearly outside the scope of a home inspection) are weighted such that the exam taker is not severely punished for answering incorrectly. This same scoring is used for questions that test minimum competency. Exam takers are not rewarded for answering easy questions correctly (questions every practicing inspector should be able to answer) but are severely punished for answering such questions incorrectly.
