A FORTRAN program for clustering variables using the alpha coefficient of reliability is described. For batch operation, a rule for stopping the agglomerative precedure is available. The conversational version of the program allows the user to intervene in the process in order to test the final solution for sensitivity to changes. (Author/JKS)

A major problem in the research concerning distributional and other properties of reliability coefficients has been the non-existence or inaccessibility of adequate test data for use in empirical verification of hypothetical conclusions. The purpose of this paper is to develop a technique for the simulation of test item scores through the use of…

The Student Evaluation of Teacher II (SET II), the new instrument presented in this manual, is designed for use in securing student evaluations of teachers below the fourth grade or, with disadvantaged students, through the sixth grade. The manual describes the history, nature, and difficulties of the student evaluation of teachers movement and…

Technical improvements, which may be made in the reliability and validity of tests through confidence scores, are discussed. However, studies indicate that subjects do not handle their confidence uniformly. (MS)

This partially annotated bibliography of journal articles, dissertations, convention papers, research reports, and a few books and unpublished manuscripts provides a comprehensive coverage of work on latent trait theory and practice. Documents are arranged alphabetically by author. The period covered ranges from the early 1950's to the present.…
