Lord's, Millman's and Saupe's methods of approximating the standard error of measurement are reviewed. Through an empirical demonstration involving 200 university classroom tests, all three approximations are shown to be biased. (Author/JKS)

Prior research with the Professional and Career Administrative Examination (PACE), a multiple abilities test battery for federal candidates, demonstrated practice effects (score gains) on alternate forms of the test parts within one administration of the battery. These effects were largest for those abilities including item types constructed…

Two approaches to the validation of occupational interest inventories are considered. The approaches vary according to whether one is interested in predicting students' occupational preferences as opposed to assisting counselors in advisement. One empirical example using female college students is presented. (Author/JKS)

The biasing effects of a pretest on subsequent post-test results were investigated in two experimental studies. In general, the results argue for using designs without pretests. (Author/JKS)

A basic structure approach is proposed for obtaining multidimensional scale values for attitude, achievement, or personality items from response data. The technique permits the unconfounding of scale values due to response bias and content and partitions item indices of popularity or difficulty among a number of relevant dimensions. (Author/BH)

Geometric approaches to representing interrelations among tests and items are compared with an additive tree model (ATM), using 2,644 examinees and 2 other data sets. The ATM's close fit to the data and its coherence of presentation indicate that it is the best means of representing tests and items. (TJH)

Undergraduate students were administered one of three conventional or one of three stratified adaptive vocabulary tests with or without knowledge of results. Results indicated that knowledge of results and test difficulty affected performance. (Author/JKS)
