The scores on two distinct tests (e.g., essay and objective) are often combined into a composite score, which is used to make decisions. The validity of the observed composite can sometimes be evaluated relative to a separate criterion. In cases where no criterion is available, the observed composite has generally been evaluated in terms of its…

The scores on 2 distinct tests (e.g., essay and objective) are often combined to create a composite score, which is used to make decisions. The validity of the observed composite can sometimes be evaluated relative to an external criterion. However, in cases where no criterion is available, the observed composite has generally been evaluated in…

The answer-until-correct (AUC) procedure requires that examinees respond to a multi-choice item until they answer it correctly. Using a modified version of Horst's model for examinee behavior, this paper compares the effect of guessing on item reliability for the AUC procedure and the zero-one scoring procedure. (Author/CTM)

The aims of this study were: (1) to review and discuss alternatives for evaluating members of a set of scores which may be interpreted independently as contributing to a composite score, or as a member of a profile and (2) to examine multivariate generalizability theory, as suggested by Joe and Woodward, applied to student course/instructor…
