Operational testing programs employing item response theory (IRT) applications benefit from of the property of item parameter invariance whereby item parameter estimates obtained from one sample can be applied to other samples (when the underlying assumptions are satisfied). In theory, this feature allows for applications such as computer-adaptive…

This study examined the cross-lingual equating process adopted by a large scale testing system in which target language (TL) forms are equated to the source language (SL) forms using a set of translated items. The focus was on evaluating the degree of error inherent in the routine cross-lingual equating of the Verbal Reasoning subtest of the…

Only a slight decrease in the percentage passing the eighth-grade social studies test marred the otherwise across-the-board rise in percentages meeting minimum…

The research leading to the decisions to revise the Graduate Record Examination Aptitude Test (GRE) (beginning in October 1981) is reviewed. The issues discussed include the format of the test (the timing of each section and the number of sections, the content of the sections--especially the analytical section), the scoring procedure for the GRE,…

The primary objective of this study was to investigate overall patterns of gender differences and similarities of test performance in mathematics. To achieve that objective, observed test scores on the Delaware standards-based assessment were analyzed to examine: (1) gender differences and similarities across grades 3, 5, 8 and 10 over 2 years;…
