Attali (2005) recently demonstrated that Cronbach's coefficient [alpha] estimate of reliability for number-right multiple-choice tests will tend to be deflated by speededness, rather than inflated as is commonly believed and taught. Although the methods, findings, and conclusions of Attali (2005) are correct, his article may inadvertently invite a…

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)

Binary, probability, and ordinal scoring procedures for multiple-choice items were examined. In two situations, it was found that both the probability and ordinal scoring systems were more reliable than the binary scoring method. (Author/CTM)

A comparison of the relative ordering power of separate and grouped-items true-false tests indicated that neither type of test was uniformly superior to the other across all levels of knowledge of examinees. Grouped-item tests were found superior for examinees with low levels of knowledge. (Author/CTM)

A multiple matching test--a 24-item Hebrew vocabulary test--was examined, in which distractors from several items are pooled into one list at the test's end. Construction of such tests was feasible. Reliability, validity, and reduction of random guessing were satisfactory when applied to data from 717 applicants to Israeli universities. (SLD)
