Introduction: Audience and requisite background. Role of DIF investigation. Fairness and DIF. Bias and DIF. DIF and discrimination. Understanding the term DIF.

Differences are systematic. Matching on ability or proficiency. Conditioning criterion: internal versus external. Purification of data -- Important considerations: DIF: statistics versus reasoned judgment. statistical bias is not unfairness. Whole test versus individual items. Number: items and sample. A sensible perspective -- History of test bias and DIF: Standards for test fairness -- Quick-but-incomplete methods: Ordinal ranking of items. Ability group methods.
