Six papers on applications of item response theory are presented. Applications involved include item bias, criterion-referenced measurement problems, test score equating, computerized ability testing, information processing approaches, unidimensional binary responses, multidimensional and polychotomous responses, and estimation and goodness of…

A basic technical framework is provided for the design and use of mastery tests. The Mastery Testing Project (MTP) prepared this framework using advanced mathematics supplemented with computer simulation based on real test data collected by the South Carolina Statewide Testing Program. The MTP focused on basic technical issues encountered in using…
