The purpose of this study was to evaluate the effectiveness of the NCAT administered in December 1961 for predicting freshman college GPA and Naval Science Course grades. High school ratings were validated along with NCAT total and subtest scores for 1345 midshipment from 42 of the 52 colleges participating in the NROTC Regular program. Analyses were made for each school and for the entire sample. Validities of NCAT subtest and total scores were lower than those obtained in three earlier years. The validity of high school ratings for the 1961 sample, however, was similar to those previously obtained. Results of item analysis of one NCAT subtest suggested that improved item selection procedures would be required to increase NCAT validity to earlier validity levels. Author
