Background information, Comrey Personality Scale scores, and a standard Navy aptitude test score were obtained on 600 Navy enlisted men and 600 Navy enlisted women prior to beginning Naval Hospital Corps School training. A comparison of the men and women indicated that the sexes differed on a number of background and personality dimensions. A double‐split cross‐validation design with multiple regression was then employed in the development of a test battery for predicting school completion. Results indicated that the men were more predictable than the women with cross‐validities on the order of .53 for men and .41 for women. For the total sample, cross‐validities were approximately .47. An empirical comparison of the utility of these equations for screening candidates for paramedical training suggested that the use of separate equations with the sexes would not produce results which were substantially different from use of the single equation developed on both sexes c
