Mechanisms¶
- Subgroup Outcome-Validity Dashboard
- Its habit of pairing outcome gaps with reliability evidence is close in spirit to differential item functioning analysis, which asks whether equally-able people from different groups are scored differently — a validity question, not merely an outcome one.
This sourceDefines differential item functioning as different item behavior across groups among examinees matched on ability.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
