Classical test theory has been rejected for application to criterion-referenced (CR) tests by most psychometricians due to an expected lack of variance in scores and other difficulties. The present study was conceived to resolve the variance problem and explore the possibility that classical test theory is both appropriate and desirable for some…

A new approach to polychotomous scoring of test items, similar to "max-alpha" scaling (MAS) and known as polyweighting, has been developed. Unlike MAS, this new method of polychotomous scoring provides scoring weights for a given item that are independent of the difficulty of other items in the analysis. Moreover, the scoring weights are…

The proposition that the optimal number of options in a multiple choice test item is three was examined. The concept of functional distractor, a plausible wrong answer that is negatively discriminating when total test performance is the criterion, is discussed. Three distinct groups of achievers (high, middle, and low) on a national standardized…

The purpose of this study is to examine an option-weighting method as it affects pass-fail decisions in formative and summative evaluation of student achievement for instructional units, certification, advancement, licensure, admissions, placement, and selection. A database was constructed using high school achievement test data where a…

In this paper 45 item-writing rules for multiple-choice tests presented in textbooks on educational measurement in a previous study are identified. The current study presents a quantitative review of the literature with respect to the empirical and theoretical evaluation of these principles of item-writing. Fifty-six studies that addressed at…

Because of the importance of standardized test scores in current definitions of educational achievement, pressure to raise test scores has affected their accuracy. Examines the causes of two major sources of test score pollution and their impact on education. Discusses the ethical status of documented test-preparation activities. (CJS)
