* The "Impact Ratio" is calculated by dividing each group's selection rate by the highest selection rate among all groups.
Evaluate selection rates to determine potential adverse impact
HR, legal, recruiting, and people analytics teams use an adverse impact four-fifths rule check to compare selection rates across demographic groups in hiring, promotion, testing, or reduction-in-force decisions. The calculator flags impact ratios below 80 percent so teams can identify selection procedures that may need validation, review, or legal analysis.
Under the Uniform Guidelines, a selection rate for one group that is less than four-fifths of the rate for the group with the highest selection rate is generally regarded as evidence of adverse impact.
No. It is a screening rule, not a final legal conclusion. Sample size, job relatedness, validation evidence, and the full employment process matter.
The common four-fifths calculation compares each group with the group that has the highest selection rate. Some analyses may also use a legally or statistically appropriate reference group.
Yes. It can be applied to any selection procedure, including hiring, promotion, testing, certification, termination, or reduction decisions, when group counts and outcomes are available.
