Assessment quality infographic with reliability and validity gauges, governance checklist, and readiness score thresholds for personality test deployment.
Reliable decisions require both psychometric evidence and governance controls.

This checker is a screening aid. Final deployment decisions should be reviewed by a qualified psychometric specialist.

Quick answer

What does this checker score?

It combines psychometric coefficients and governance controls into a readiness score, helping you decide whether a test is suitable for high-stakes deployment.

Why this tool matters

Many personality tests look polished but provide limited deployment evidence. This checker quickly highlights whether evidence quality is strong enough for real decisions.

Guardrails

Use-before-deploy checks

  • Verify published reliability and validity documents.
  • Document subgroup fairness monitoring.
  • Avoid using low-readiness tools as gatekeepers.
  • Run recurring quality audits on live outcomes.

FAQ

Is a high alpha enough to deploy a test?

No. Alpha alone does not guarantee construct validity, fairness, or stability.

Can this checker replace psychometric review?

No. It is a triage and decision-support layer, not a full technical audit.

What is the most common missing control?

Transparent norm sample documentation and adverse impact monitoring.
