Use when building validity evidence by linking selection-procedure content to the work domain — demonstrating that the procedure samples important work behaviors, activities, and/or worker KSAOs defined by an analysis of work. Covers defining the content domain, SME qualifications and linkage judgments, sampling the domain, fidelity/specificity, competency-model foundations, and evaluating content evidence. Triggers: "content validity", "content-based strategy", "work sample", "job knowledge test", "link test content to the job", "SME linkage ratings", "no criterion data available".
