Describes the role of information on score reliabilities, significance of score differences, intercorrelations of scores, and differential validity of score patterns on the interpretation of results from multiscore batteries. (Author)

Reviews the 1974 Standards, an updating serving as a guide to test making and publishing, and training of persons for these endeavors. (DEP)

Three professional associations, the American Educational Research Association, the American Psychological Association, and the National Council on Measurement in Education, jointly adopted the new "Standards for Educational and Psychological Testing" in 1985. The relationship of these to earlier standards is reviewed, and implications…

Empirical results are presented as regards the implementation of a latent-trait psychometric model by means of conditional maximum likelihood estimation. Items are scored polychotomously into varying numbers of nominal categories and the test and item characteristic curves and information functions are examined. It is concluded that scoring items…

An attempt is made to indicate why the concept of "true score" naturally leads to the belief that test validity must increase with an increase in test and/or average item reliability, and why this is correct for the classical single-factor model first introduced by Spearman. The statistical model used by Loevinger is introduced to…

Presents a comprehensive review of validity that includes an empirical evaluation of the actual and potential consequences of score interpretation and use, how those consequences come about, and what determines them. Six distinguishable aspects of construct validity are highlighted as a means of addressing central issues implicit in the notion of…
