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…

"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…

Recent assessment research joining cognitive psychology and psychometric theory has introduced a new technology, item generation. In algorithmic item generation, items are systematically created based on specific combinations of features that underlie the processing required to correctly solve a problem. Reading comprehension items have been more…

The study evaluated the invariance of the construct validity and thus the interpretation of Graduate Record Examinations (GRE) Aptitude Test scores. A systematic procedure for investigation of test bias from a construct validity frame of reference was developed and applied. Invariant construct validity was defined as similar patterns of loadings…

We describe the item modeling development and evaluation process as applied to a quantitative assessment with high-stakes outcomes. In addition to expediting the item-creation process, a model-based approach may reduce pretesting costs, if the difficulty and discrimination of model-generated items may be predicted to a predefined level of…
