Correction for guessing does not fulfill its intended function when test takers who have nothing to gain from scoring will respond randomly when they could have answered correctly had they tried. Raw scores underestimate abilities. If random guessing is more prevalent in the control group, correction for guessing inflates treatment effects.…

Using data from the SCRE Criterion Test composition papers, the author tests the hypothesis that the bulk of inter-marker unreliability is caused by inter-marker inconsistency--which is not correctable statistically. He suggests that a shift to "consensus" standards will realize greater improvements than statistical standardizing alone.…

The present study was an attempt to alleviate some of the difficulties inherent in multiple-choice items by having examinees respond to multiple-choice items in a probabilistic manner. Using this format, examinees are able to respond to each alternative and to provide indications of any partial knowledge they may possess concerning the item. The…

In a study to determine whether a shift from Formula scoring to Rights scoring can be made without causing a discontinuity in the test scale, the analysis of special administrations of the Scholastic Aptitude Test and Chemistry Achievement Test and the variable section of an operational form of the Graduate Management Admission Test (GMAT) is…

The purpose of this study was to determine whether it would be possible to equate rights-scored to formula-scored tests without causing a discontinuity in the meaning of the score scale. Several other subsidiary studies--of the characteristics of the two scoring methods, of nonresponse and guessing, and of reliability and parallelism--were also…

The author surveys literature and practice, primarily in Great Britain and the United States, about multiple-choice testing, comments on criticisms, and defends the state of the art. Varous item types, item writing, test instructions and scoring formulas, item analysis, and test construction are discussed. An extensive bibliography is appended.…

This study reexamines results reported by Angoff and Schrader regarding formula directions and rights directions for standardized tests. In that study, it was concluded that the two scoring directions were essentially equivalent. In this study, methodological concerns are discussed and additional data analyses undertaken. Among various…
