VALIDATION OF THE 1963 NAVY COLLEGE APTITUDE TEST.
Abstract
This study of the validity of the 1963 Navy College Aptitude Test (NCAT) and of other academic predictors was based on a sample of 1,307 freshmen enrolled in the 1964-65 NROTC Regular program. The NCAT Selection Score yielded corrected correlations of .24 with Grade Point Average (GPA) and .14 with Naval Science Grade (NSG). The High School Rating (HSR) continued to be the most valid single predictor of college performance, producing corrected correlations of .46 with GPA and .31 with NSG. When HSR was combined with the NCAT, the validity was increased to .48 with GPA but no increment was noted for NSG. A comparison of the 1963 NCAT with the Scholastic Aptitude Test indicated the former to be slightly more valid. Neither test demonstrated significant differential prediction between groups dichotimized by technical and non-technical college majors. The rate of attrition for this midshipmen sample was 15 per cent, compared to the national rate for male freshmen of 30 per cent. From these figures it was estimated that the reduction in freshmen dropouts saved the Navy at least $424,600 in Fiscal Year 1966. (Author)
