Current methods for obtaining reliability indices for mastery tests can be laborious. This paper offers practitioners tables from which agreement and kappa coefficients can be read directly and provides criterion for acceptable values of agreement and kappa coefficients. (TJH)

In mastery testing, the raw agreement index and the kappa index may be estimated via one test administration when the test scores follow beta-binomial distributions. This paper reports formulae, tables, and a computer program which facilitate the computation of the standard errors of the estimates. (Author/CTM)

Procedures are described for studying the reliability of decisions based on specific passing scores with tests made up of discrete items and designed to measure continuous rather than categorical traits. These procedures are based on the estimation of the joint distribution of true scores and observed scores. (CTM)

This journal issue addresses the topic of mastery learning at both the elementary and secondary school levels. The first article, "The Theory and Practice of Mastery Learning" (Guskey), gives a definition of and information about the development, operation, and application of mastery learning, based on the theories of Benjamin Bloom.
