CPI (NCCT)

It is the Certified Professional Inspector® designation associated with InterNACHI®, the International Association of Certified Home Inspectors. InterNACHI® states that it provides online testing and certification and that it offers the world's most respected inspector certification program, according to its own description. Treat the designation as an association certification, not a government license.

Two groups. People starting out who need training, licensing help, and help setting up a company, and established inspectors who want a certification to stand out and access to business development and marketing resources. InterNACHI® also addresses multi-inspector firms that want to hire, expand, or sell.

Those figures are not published on the InterNACHI® pages retrieved for this profile, so we do not state them. Confirm the current question count, time limit, and passing score with InterNACHI® before scheduling. Any specific number you see elsewhere may be outdated.

This study page organizes content into four areas: Standards of Practice; roofing, structure, and exterior systems; plumbing, electrical, and HVAC; and interior, insulation, ventilation, plus inspection business and ethics. That breakdown is this site's study structure, not an official published blueprint. Use it to plan review, then check InterNACHI® materials for official scope.

Start with the Standards of Practice, because inspection reporting language and defect-calling decisions depend on it. Then work system by system: structure and exterior, then plumbing, electrical, and HVAC, then interior, insulation, and ventilation. Finish with business and ethics. InterNACHI® offers over 1,000 hours of free online education for members and a free online exam for self-testing.

Yes. InterNACHI® lists a free online exam described as a way to test and improve yourself. Use it as a diagnostic, not as your only preparation. Pair it with course material and with the practice questions on this page, and review every missed item until you can explain why the correct answer is correct.

Three recur. First, answering what you would do as an inspector instead of what the Standards of Practice require. Second, over-calling: labeling a cosmetic issue as a defect. Third, weak vocabulary on electrical and HVAC components. Slow down on questions that ask what must be reported versus what is excluded.

Retake rules, waiting periods, and any fees are not stated on the InterNACHI® pages retrieved for this profile, so we do not guess. Ask InterNACHI® directly about retake policy before you sit the exam, and note that membership benefits may affect your access to training and testing.

InterNACHI® states that All-Access Membership gives access to nearly all benefits while you work toward certification at your own pace at no additional cost, and that members get over 1,000 hours of free online education. It also offers an 85+ page membership guide covering membership, education, marketing, specialty programs, media, events, and partners.

No. This is independent study material written for candidates preparing for the CPI credential. It is not affiliated with, endorsed by, or sponsored by InterNACHI®, and it does not reproduce official exam questions. Always verify exam logistics, fees, and requirements with InterNACHI® directly.
