4/5 Rule Calculator

The 4/5 Rule Calculator is a critical tool used in the field of human resources and employment law to assess potential discrimination in hiring or selection processes. This rule is a guideline established by the U.S. Equal Employment Opportunity Commission (EEOC) to identify adverse impact in employment decisions.

Historical Background

The 4/5 Rule, also known as the 80% Rule, was established as part of the Uniform Guidelines on Employee Selection Procedures in 1978. It serves as a benchmark for determining whether there is evidence of discrimination in hiring and selection practices.

Calculation Formula

The 4/5 Rule is calculated as follows:

\[ \text{Ratio} = \frac{\text{Selection Rate of the Protected Group}}{\text{Selection Rate of the Highest Group}} \]

If the ratio is less than 0.80 (or 4/5), it indicates a potential adverse impact on the protected group.

Example Calculation

Suppose the selection rate for a protected group is 15% and for the highest group is 20%:

\[ \text{Ratio} = \frac{15\%}{20\%} = 0.75 \]

Since the ratio is less than 0.80, it suggests a potential adverse impact.
