Knowledge, Skills, and Abilities (KSAs) for Competent Inspection
The KSA domain tests whether you understand what competence looks like, not just facts. Knowledge includes building science fundamentals, common construction methods and materials by era, the standards of practice and code of ethics you are bound to, and the reporting standards for your jurisdiction. Skills are the observable performances: safe use of tools and test instruments, systematic inspection routines that avoid skipped areas, clear technical writing, and professional communication with clients and agents. Abilities are the underlying capacities that let those skills hold up under real conditions - sound judgment, pattern recognition, situational awareness, and the discipline to stay within scope when a client pressures you to go beyond it.
Questions frequently probe the boundaries of competence. Expect items about referring to specialists when a condition exceeds your training, declining to offer engineering opinions, and recognizing that continuing education and ride-alongs maintain competence. Also expect items on safety: personal protective equipment, ladder and roof safety, electrical safety around panels, and combustion safety. Ethical KSAs appear too - avoiding conflicts of interest, not accepting referral fees, and not repairing defects you inspected where your standards prohibit it.
Worked example: While inspecting a panel, you notice a conductor that appears undersized for its breaker. You are competent to observe and describe the condition and recommend evaluation by a licensed electrician; you are not competent to declare it a code violation with certainty unless your standards and training support that call. Rule of thumb: describe what you see, state why it matters, and route the definitive determination to a qualified specialist.
