Equating error is usually small relative to the magnitude of measurement error, but it could be one of the major sources of error contributing to mean scores of large groups in educational measurement, such as the year-to-year state mean score fluctuations. Though testing programs may routinely calculate the standard error of equating (SEE), the…

In this study we examined variations of the nonequivalent groups equating design for tests containing both multiple-choice (MC) and constructed-response (CR) items to determine which design was most effective in producing equivalent scores across the two tests to be equated. Using data from a large-scale exam, this study investigated the use of…

Several current international comparative large-scale assessments of educational achievement (ICLSA) make use of "Rasch models", to address functions essential for valid cross-cultural comparisons. From a historical perspective, ICLSA and Georg Rasch's "models for measurement" emerged at about the same time, half a century ago. However, the…

A description is given of an experiment on methods of testing, conducted with a mathematics course at University of California - Davis. (PK)

Investigated the effect of examiners' ethnicity on the intelligence test performance of Anglo and Mexican-American subjects. On the WISC Vocabulary, Mexican-American subjects scored significantly higher when the test was administered by Mexican-American examiners. (Author)

Describes the rationale underlying computerized adaptive testing (CAT), discusses the psychometric and technical developments which make it practical, and reviews some previous work which has shaped the current state of the art. The possible advantages, constraints, and operational requirements, and possible areas of application are examined.…

The score distributions of the two methods of administration described in the title revealed comparable means, standard deviations, and general shape of distribution. With respect to validity coefficients, no appreciable differences were found. (JKS)

Student test scores are increasingly used to judge the competence of the educational enterprise. Exaggeration of scores is the result of directing attention away from the individual student achievement to the average scores of schools, districts, and states. Implications and recommendations are discussed. (BJV)
