NWFA CI study guide
NWFA CI · Work through your exam, one topic at a time.
The NWFA Certified Inspector (CI) is one of five credentials in the National Wood Flooring Association's Certified Professional program, listed alongside Certified Sales Advisor, Certified Professional, Certified Sand & Finish, and Certified Installer. The NWFA describes the program as one that "validates your industry knowledge and expertise and recognizes you as an expert in your field," and it lists certified professionals exclusively in its Find a Professional directory - so the credential functions as a public, searchable signal of competence rather than an internal title. It is aimed at wood flooring professionals who investigate and evaluate flooring conditions and performance, and who want third-party recognition of that expertise. This page is an independent study resource and is not affiliated with or endorsed by the NWFA; always confirm exam logistics, eligibility, and fees directly with the association. Note that the NWFA's dedicated certified-inspector page returned a "page not found" error when this page was last checked, so the association's Certifications landing page is currently the most reliable starting point for program details. Preparation should combine the NWFA's technical standards and publications, its hands-on training and NWFA University courses, and its webinars - the same activities that earn continuing credit units. Topics on this exam: Certified Inspector body of knowledge. The NWFA CI study guide has 1 section and about 373 words.
01Certified Inspector Body of Knowledge
This domain tests objective wood-floor inspection: collecting job history, measuring moisture and dimensions with calibrated instruments, comparing results with the NWFA Installation, Sand & Finish, and Inspection Guidelines plus manufacturer instructions, and writing a cause-based report instead of a personal opinion. Inspect before repairs begin; document existing conditions, HVAC operation, cleaning products, and installation date. Concrete moisture: ASTM F2170 in-situ RH probes are preferred; ASTM F1869 calcium chloride is an alternative. Typical limits are about 75% RH or 3 lb/1,000 ft²/24 h, but the adhesive or flooring manufacturer's limit controls.
