Effects of Item Characteristics on Test Fairness.
Abstract
This report examines how selection fairness is influenced by the item characteristics of a selection instrument in terms of its distribution of item difficulties, level of item discrimination, and degree of item bias. Computer simulation was used in the administration of conventional ability tests to a hypothetical target population consisting of a minority and a majority subgroup. Fairness was evaluated by three indices which reflect the degree of differential validity, errors in prediction (Cleary's model) and proportion of applicants exceeding a selection cutoff (Thorndike's model).
