Validation is the study of an employer's test or selection standards that proves that they are significant predictors of successful job performance (those who score high turn out to be successful on a job and those who score low turn out to be unsuccessful). The study requires a large sample of applicants and must include representatives of groups--such as minorities and women--who may be suffering adversely from such standards.
