THE CONTRIBUTION OF ACADEMIC INTEREST MEASURES TO THE DIFFERENTIAL PREDICTION OF MARKS

Abstract

In a study of differential predictions of course marks in grades 12 and 13 interest measures were found to add appreciably to differential validities, particularly at the high school level. Differential validities remained quite low; however–typically in the .20's and .30's‐probably because of high intercorrelations among the criteria. The relationship between intercorrelations of actual criteria and intercorrelations of predicted criteria was examined, and the implications of this relationship for differential validities were discussed.
