Validity and Fairness
Kane, Michael
Language Testing, v27 n2 p177-182 2010
This paper presents the author's critique on Xiaoming Xi's article, "How do we go about investigating test fairness?," which lays out a broad framework for studying fairness as comparable validity across groups within the population of interest. Xi proposes to develop a fairness argument that would identify and evaluate potential fairness-based objections to proposed interpretations and uses of the test scores. The fairness argument would focus on whether an interpretation is equally plausible for different groups and whether the decision rules are appropriate for the groups. The model combines fairness and validity in a common framework. The author contends that the relationship between validity and fairness depends on how individuals define these two concepts, and perhaps more to the point how broadly individuals define each of these concepts. If one defines validity narrowly and fairness broadly, then validity could be conceived of as a component of fairness; if one defines fairness in terms of a specific technical issue, like predictive bias and validity broadly, then fairness could be conceived of as a component of validity. The author defines both validity and fairness quite broadly, and he does not see either of these concepts as being completely included within the other. Rather, he sees them as closely related ways of looking at the same basic question: Are the proposed interpretations and uses of the test scores appropriate for a population over some range of contexts. Validity and fairness come at the question from somewhat different points of view and involve different emphases, but the overlap is more pronounced than the differences.
