Adverse impact

This dashboard monitors pass-rate equity across demographic groups using the four-fifths rule (the 80% impact ratio) — the long-standing benchmark used by US EEOC and Canadian human-rights regulators to flag selection processes that may have disparate impact.

What you see​

Snapshots are computed weekly by a worker job. For each demographic category (e.g., gender, ethnicity), the dashboard shows two charts:

  • Impact ratios — bar chart per group with the 0.8 threshold drawn as a reference line. Groups below 0.8 render in red.
  • Pass rates — bar chart showing the absolute pass rate per group.

A detail table follows with: group, candidates completed, candidates passed, pass rate %, impact ratio, flagged status.

What the impact ratio means​

For each group, the impact ratio is its pass rate divided by the highest- pass-rate group's rate. A ratio below 0.8 means the group's pass rate is less than 80% of the reference group — the regulatory red flag.

A flagged group is not necessarily bias; small-N volatility is common, and the dashboard surfaces the candidate count so analysts can judge significance. Persistent flags across multiple snapshots warrant deeper investigation: is the template construct-valid? Are particular questions driving the gap (see Item analysis)?

What it is not​

This dashboard is descriptive, not causal. It tells you a gap exists; it doesn't tell you why. Action belongs with HR, legal, and the assessment content team.
