How to read an assessment's technical manual

Vendors rarely lie in a technical manual; they simply rely on you not reading it. Five figures do most of the work: criterion validity, test–retest reliability, internal consistency, the norm sample, and adverse-impact ratios.

Learn to find those five and you can triage any instrument in fifteen minutes — which is exactly what our reviewers do before they ever score a tool.
