Previous research on calculator use in standardized assessments of quantitative ability focused on the effect of calculator availability on item difficulty and on whether test developers can predict these effects. With the introduction of an on-screen calculator on the Quantitative Reasoning measure of the "GRE"® revised General Test, it…

In many testing programs it is assumed that the context or position in which an item is administered does not have a differential effect on examinee responses to the item. Violations of this assumption may bias item response theory estimates of item and person parameters. This study examines the potentially biasing effects of item position. A…

A generic approach in automated essay scoring produces scores that have the same meaning across all prompts, existing or new, of a writing assessment. This is accomplished by using a single set of linguistic indicators (or features), a consistent way of combining and weighting these features into essay scores, and a focus on features that are not…

This paper explores alternative approaches for facilitating efficient, evidence-centered item development for a new type of verbal reasoning item developed for use on the GRE® General Test. Results obtained in two separate studies are reported. The first study documented the development and validation of a fully automated approach for locating the…

This research investigated the effect on estimated lower asymptotes of the instructions to Graduate Record Examination (GRE) examinees about how the test would be scored. This effect was assessed for four different verbal item types (analogies, antonyms, sentence completion, and reading comprehension) using a two-way, unweighted means analysis of…

Content characteristics of 1,400 Graduate Record Examination (GRE) analytical reasoning items were coded for item difficulty and discrimination. The results provide content characteristics for consideration in extending specifications for analytical reasoning items and a better understanding of the construct validity of these items. (TJH)

Confirmatory multidimensional item response theory (CMIRT) was used to assess the structure of the Graduate Record Examination General Test, about which much information about factorial structure exists, using a sample of 1,001 psychology majors taking the test in 1984 or 1985. Results supported previous findings that, for this population, there…

Much of the effort involved in a major restructuring of the Graduate Record Examinations (GRE) Aptitude Test was intended to result in the creation of an analytical module to supplement the verbal and quantitative sections of the test, thus providing broadened measurement. Factor extension analysis was used in the present study to investigate…

There are many potential sources of test bias besides that of the particular item content within the test. The other potential sources, designated here as program and utilization must also be encompassed in any thorough and effective program to increase the accuracy of assessment for members of ethnic minorities. As usual, the research findings…

Since The Graduate Record Examination-Verbal measures two factors (reading comprehension and discrete verbal ability), the unidimensionality of item response theory is violated. The impact of this violation was examined by comparing three ability estimates: reading, discrete, and all verbal. Both dimensions were highly correlated; the impact was…

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…

The scope and nature of sex differences in the Graduate Record Examination are explored by identifying individual test items that differ from the other items in terms of the magnitude of the difference in item difficulty for the sexes. In general, limited evidence of differences was established. (Author/CTM)

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…

"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…

This Graduate Record Examination (GRE) study assesses: (1) the relative contribution of a vocabulary score (consisting of GRE General Test antonyms and analogies) and a reading comprehension score (consisting of GRE sentence completion and reading comprehension sets) to the prediction of self-reported undergraduate grade point average (GPA); and…
