An index for the dependability of mastery tests is described. Assumptions necessary for the index and the mathematical development of the index are provided. (Author/JKS)

This handbook treats a restricted set of statistical procedures for addressing some of the most prevalent technical issues that arise in domain-referenced testing. The procedures discussed here were chosen because they do not necessitate extensive computations. The five major sections of the paper cover: (1) item analysis procedures for using data…

A large number of seemingly diverse coefficients have been proposed as indices of dependability, or reliability, for domain-referenced and/or mastery tests. In this paper, it is shown that most of these indices are special cases of two generalized indices of agreement: one that is corrected for chance, and one that is not. The special cases of…

Using the basic principles of generalizability theory, a psychometric model for domain-referenced interpretations is proposed, discussed, and illustrated. This approach, assuming an analysis of variance or linear model, is applicable to numerous data collection designs, including the traditional persons-crossed-with-items design, which is treated…

The first four chapters of this report primarily provide an extensive, critical review of the literature with regard to selected aspects of the criterion-referenced and mastery testing fields. Major topics treated include: (a) definitions, distinctions, and background, (b) the relevance of classical test theory, (c) validity and procedures for…
