First grade students stratified on the basis of their racial-ethnic and socioeconomic status (SES) were studied to determine factors measured by several readiness (aptitude) tests and to learn whether these factors differed for the children from the various groups. SES was determined by father's occupation, or if absent, mother's occupation; the…

Statistical procedures are presented for determining ordinal and disordinal aptitude-treatment interactions with linear and curvilinear data. The paper presents a method for testing the homogeneity of group regressions for a single aptitude and provides models for expanding this test to linear and curvilinear regression planes. Procedures are…

The nature of the relations between traditional psychometric and Piagetian instruments is analyzed, in order to provide information relevant to the question of which type of test or combination of them will provide the most useful information to those seeking to construct and maintain optimal learning environments.

This paper concerns two features of a project on the assessment of job potential: the J-Coefficient, and the J-Scale. The J-Coefficient is a means of determining the validity of a test for a position on the basis of (1) the Beta Weights for predicting test scores from a set of elements and (2) estimates of importance of each element in the…
