This study explores the predictive validity, versus generalized grade-average criteria within each of several liberal arts colleges, of a standard composite of four admissions scores, weights for which were determined by an application of the method of multiple discriminant analysis to data for several college/level of achievement groups. One linear discriminant function of the four admissions scores (SAT-V, SAT-M, Rank, and CEEB Achievement Average) exhausted more than 90 percent of their predictive power for separating 16 criterion groups. The corresponding discriminant score yielded validity coefficients versus freshman- and senior-level grade average criteria comparable to those yielded by regression-weighted predicted composites.
