Predictive validity
Predictive validity is the correlation between an assessment score and a later job outcome — performance rating, promotion, retention, revenue. It is the single most important quality of any hiring or promotion tool: does this predict what we care about?
Why it matters for HR leaders
Unstructured interviews correlate around r=0.20 with performance. Well-designed simulations exceed r=0.50. The gap is the difference between guessing and knowing.
