Welcome to InterNACHI's Online Inspector Examination. This is a completely free exam that is one of many
InterNACHI entrance requirements. It's free and open to everyone, and
you can take it as many times as you like.
Please note that this exam is also an entrace requirement for the National Association of Certified Home Inspectors, Inc. and
CalNACHI.
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.
The scoring system is very advanced. Each item is validated to determine the relative importance on assessing the
exam takers knowledge and skill, as is each answer to each question. Then each is weighted accordingly. 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 are not rewarded for answering easy questions (questions every practicing inspector
should be able to answer) but are severely punished for answering such questions incorrectly.
