Certified Flooring Safety Inspector Instructor (NFSI) NFSI candidates often overlook the distinction between ADA slip-resistance standards and ASTM testing methods, conflating them into one requirement. The exam probes this gap relentlessly, as does real-world inspection where specifying the wrong coefficient of friction can invalidate a flooring installation. Mastering both frameworks separately—not as interchangeable concepts—separates passing from failing scores.
