Abstract | A variety of terms related to test bias or test fairness have been used in a variety of ways, but in this document the "fair use of tests" is defined as equitable selection procedures by means of intact tests, and "test item bias" refers to the study of separate items with respect to the tests of which they are a part. Seven different operational definitions of the fair use of tests are described; distinctions made between those applied to fairness for individuals who are members of special groups, and those applied to fairness for groups but not their individual members. All seven approaches use the regression model. One method also requires the use of expected utilities. Various methods are described for investigating test item bias. Both classical test theory item analysis and latent trait item characteristic curve approaches are mentioned. Tests for bias included analysis of variance, chi-square, factor analysis, and arbitrary confidence bands. Distractor responses and item-test point-biserial correlations have also been considered. All of these methods are described briefly, but no attempt was made to evaluate them. (CTM) |
