The Wisconsin Card Sorting Test (WCST) assesses executive and frontal lobe function and can be administered manually or by computer. Despite the widespread application of the 2 versions, the psychometric equivalence of their scores has rarely been evaluated and only a limited set of criteria has been considered. The present experimental study (N =…

This article reports the results of a study of potential sources of item nonequivalence between English and Chinese language versions of a cognitive development test for preschool-aged children. Items were flagged for potential nonequivalence through statistical and judgment-based procedures, and the relationship between flag status and item…

The Assessment of Language Competence (ALC) certificates is an annual, international testing program developed by the Australian Council for Educational Research to test the listening and reading comprehension skills of lower to middle year levels of secondary school. The tests are developed for three levels in French, German, Italian and…

The gold standard in making causal inference on program effects is a randomized trial. Most randomization designs in education randomize classrooms or schools rather than individual students. Such "clustered randomization" designs have one principal drawback: They tend to have limited statistical power or precision. This study aims to…

A procedure for checking the score equivalence of nearly identical editions of a test is described and illustrated with Scholastic Aptitude Test data. The procedure uses the standard error of equating and uses graphical representation of score conversion deviations from the identity function in standard error units. (SLD)

Equating a new standard test to an old reference test is considered when samples for equating are not randomly selected from the target population of test takers, identifying two problems from equating from biased samples. An empirical example with data from the Armed Services Vocational Aptitude Battery illustrates the approach. (SLD)

Determining the optimal number of choices on a multiple-choice test is explored analytically from an information theory perspective. The analysis revealed that, in general, three choices seem optimal. This finding is in agreement with previous statistical and psychometric research. (SLD)

Comparability of the Minnesota Multiphasic Personality Inventory (MMPI) and the MMPI-2 was explored by examining T-score means, profile configurations, score distribution, and rank-order correlations on validity scales for 84 undergraduates. Equivalency of the two forms was generally supported. (SLD)

Combinations of five methods of equating test forms and two methods of selecting samples of students for equating were compared for accuracy. The two sampling methods were representative sampling from the population and matching samples on the anchor test score. The equating methods were: (1) the Tucker method; (2) the Levine method; (3) the…

An attempt was made to evaluate the standard error of equating (at the mean of the scores) in an ongoing testing program. The interest in estimating the empirical standard error of equating is occasioned by some discomfort with the error normally reported for test scores. Data used for this evaluation came from the Admissions Testing Program of…

The traditional multiple-choice reading comprehension test of English as a second language, used in the Dutch school-leaving examinations, has been criticized for its apparent lack of construct validity. The Dutch National Institute for Educational Measurement has conducted a number of studies to determine whether there is a different skill…

This paper focuses on the questions which arise as test practitioners monitor score scales derived from latent trait theory. Large scale assessment programs are dynamic and constantly challenge the assumptions and limits of latent trait models. Even though testing programs evolve, test scores must remain reliable indicators of progress.…
