This comprehensive "Handbook" focuses on the most used polytomous item response theory (IRT) models. These models help us understand the interaction between examinees and test questions where the questions have various response categories. The book reviews all of the major models and includes discussions about how and where the models…

Compared the Nedelsky (L. Nedelsky, 1954) and Angoff (W. Angoff, 1971) standard-setting methods in three studies involving 80 graduate students as judges. Nedelsky cutscores were significantly lower than Angoff cutscores. Suggests that combining the strong features of both methods would make a better standard-setting procedure. (SLD)

The psychometric characteristics of the Graduate Record Examinations General Test (GRE-GT) were studied for three handicapped groups. Experimental subjects took the GRE-GT between October 1981 and June 1984; they include: (1) 151 visually-impaired students taking large-type, extended-time administrations; (2) 188 visually-impaired students taking…

Differences in test response characteristics between black and white, male and female groups who took the Admission Test for Graduate Study in Business (ATGSB) in February, 1971, were examined. Three studies were covered: 1) a study of the interactions between the difficulty level of test items and group membership for the above mentioned groups,…

"Item models" (LaDuca, Staples, Templeton, & Holzman, 1986) are classes from which it is possible to generate/produce items that are equivalent/isomorphic to other items from the same model (e.g., Bejar, 1996; Bejar, 2002). They have the potential to produce large number of high-quality items at reduced cost. This paper introduces…
