The analytical decomposition demonstrates how the effects of item characteristics, test properties, individual examinee responses, and rounding rules combine to produce the item deletion effect on the equating/scaling function and candidate scores. The empirical portion of the report illustrates the effects of item deletion on reported score…

A method is proposed for providing an absolute, in contrast to comparative, evaluation of how well two tests are equated by transforming their raw scores into a particular common scale. The method is direct, not requiring creation of a standard for comparison; expresses its results in scaled rather than raw scores, and allows examination of the…

Describes procedure for combining Stanford Achievement Test items with local supplementary items to measure individual and aggregate student performance in mathematics. Two reports are generated from the test results: a diagnostic report of student mastery of each objective and an overall score. (TE)

Estimates for the variance of empirically determined scoring weights are given. It is shown that test item writers should write distractors that discriminate on the criterion variable when this type of scoring is used. (Author)

This study compares various item option scoring methods with respect to coefficient alpha and a concurrent validity coefficient. The scoring methods under consideration were: (1) formula scoring, (2) a priori scoring, (3) empirical scoring with an internal criterion, and (4) two modifications of formula scoring. The study indicates a clear…
