How good are RA’s validated tests as predictors of job performance?
The graphic below provides a graphic representation of the relationship of typical scores from a valid test and job performance. The higher a person’s score on a valid test, the more likely he or she will be a Superior Employee. Successful Hires are those people who passed the test and turn out to be good employees. These are your “Superior Employees.” Rejects were people who failed the test and who would, indeed, have been undesirable employees. These are the “Bad Apples” you want to avoid. False Negatives are people who would failed the test and would have been good performers if they had been hired – they are “Missed Opportunities.” False Positives are people who passed the tests but should not have been hired because they turned out to be bad performers — these are “Bad Hires.” RA’s Validated tests are not perfect predictors, but they almost always give you an added measure of predictability over less valid hiring practices.
