Evaluate adopting the less discriminatory alternative: What does the evidence support?
An equally effective test with lower disparity is the specific alternative that should be evaluated, despite documented necessity.
The question
A US manufacturer uses AI to prioritize quality-inspector candidates. Both the current test and a redesigned test predict inspection accuracy equally well; the redesign produces a smaller protected-group disparity. Assume job-relatedness and business necessity are documented. What does the evidence support?

- Use both tests permanently to compare future applicants.Running both tests does not address the documented alternative decision and may create inconsistent selection practices without a defined evaluative purpose.
- Retain the current test because necessity is documented.Business necessity does not end the inquiry when an equally effective, less discriminatory alternative is documented and available.
- Declare the current test unlawful from disparity alone.A disparity can trigger analysis, but it does not by itself complete the legal finding when job-relatedness and necessity are established.
- Evaluate adopting the less discriminatory alternative. ✓Equal effectiveness combined with reduced disparity makes the redesigned test the relevant alternative for further adoption analysis.
The trap
Business necessity is not the endpoint when a comparably effective option appears to reduce protected-group disparity. How to remember it
An equally effective test with lower disparity is the specific alternative that should be evaluated, despite documented necessity.
