Abstract
In the attempt to identify or prevent unfair tests, both quantitative analyses and logical evaluation are often used. For the most part, fairness evaluation is a pragmatic attempt at determining whether procedural or substantive due process has been accorded to either a group of test takers or an individual. In both the individual and comparative approaches to test fairness, counterfactual reasoning is useful to clarify a potential charge of unfairness: Is it plausible to believe that with an alternative assessment (test or item) or under different test conditions an individual or groups of individuals may have fared better? Beyond comparative questions, fairness can also be framed by moral and ethical choices. A number of ongoing issues are evaluated with respect to these topics including accommodations, differential item functioning (DIF), differential prediction and selection, employment testing, test validation, and classroom assessment.
