Validity data (prediction of first-year grade point average) for colleges participating in the Admissions Testing Program Validity Study Service (VSS) and based on students entering college in 1964 through 1974 are summarized for the following predictors: Scholastic Aptitude Test (SAT)--verbal score, SAT--mathematical score, high school record, and these three predictors combined. No definite trends over time were apparent for SAT validities, although those obtained for 1973 and 1974 were generally among the highest observed. There was a downward trend in the validity of high school record accompanied by a slight downward trend in multiple correlations for all three predictors combined. Median validities for colleges having SAT--verbal means between 450 and 549 tended to be higher than those for colleges having means below 450 or above 550. The great majority of colleges participating in the VSS were found to be four-year colleges. Separate analyses of the small number of two-year colleges in the sample yielded slightly lower median validities for each of the predictors than those found for the total sample. (Author/EVH)
