This study examines the relationship between delivery models (the class size reduction model and the sheltered instruction model) and language development levels on the grade-level reading development of sixth-grade English learners (ELs) attending public middle schools in metro Atlanta, Georgia. The instrument used to measure grade-level mastery…

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)

Two indices for assessing the efficiency of decisions in mastery testing are proposed. The indices are generalizations of the raw agreement index and the kappa index. Empirical examples of these indices are given. (Author/JKS)

Techniques for classifying individuals into mastery or non-mastery status based on criterion-referenced test performance are investigated. Extensions of mastery classification techniques developed by Macready and Dayton are presented. The techniques are based on latent class and quasi-independence models. (Author/JKS)

A number of different reliability coefficients have recently been proposed for tests used to differentiate between groups such as masters and nonmasters. One promising index is the proportion of students in a class that are consistently assigned to the same mastery group across two testings. The present paper proposes a single test administration…

This study is an attempt to answer the following research question: can the reliability of a criterion-referenced test be accurately determined according to a multiple classification of the student's performance? Specifically, the study pursues the beta-multinomial model, which postulates the probability distribution of an examinee's degree of…

A number of different definitions and indices of reliability for mastery tests have recently been proposed in an attempt to cope with possible lack of score variability that attenuates traditional coefficients. One promising index that has been suggested is the proportion of students in a group that are consistently assigned to the same mastery…

A computer simulation study was conducted to investigate Subkoviak's index of reliability for criterion-referenced tests, called the coefficient of agreement. Results indicate that the index can be adequately estimated. (JKS)

Four different methods for estimating the proportions of testees properly classified as having mastered or not mastered test content are examined, using data from the Scholastic Aptitude Test. All four methods prove reasonably accurate and all show some bias under certain conditions. (JKS)

Descriptions are presented of two related probabilistic models that can be used for making classification decisions with respect to mastery of specific concepts or skills. Determination of cutoff scores, minimal number of items necessary, and the assessment of the quality of tests provided by the model are discussed. (Author/JKS)

Classical test construction and analysis procedures are applicable and appropriate for use with criterion referenced tests when samples of both mastery and nonmastery examinees are employed. (Author/BB)

Two approaches to criterion-referenced measurement are described and contrasted--domain-referenced testing and mastery testing. This paper is organized according to ten issues or stages in test construction: (1) content domain specification; (2) item construction; (3) item domain specification; (4) item analysis; (5) item selection; (6) parallel…

A defense of the use of standards with criterion-referenced testing is made in response to Glass's article (TM 504 031). (JKS)

Several Bayesian approaches to the simultaneous estimation of the means of k binomial populations are discussed. This has particular applicability to criterion-referenced or mastery testing. (Author/JKS)

A unique system is described for creating tests by computer. It is unique because, instead of storing items in the computer, item algorithms similar to Hively's notion of item forms are banked. Every item, and thus every test, represents a sample from domains consisting of thousands of items. The paper contains a discussion of the special…
