This research investigated the effectiveness of the Hand Skills Test, or HST (motivation), Navy Activities Preference Blank (NAPB), and the Navy Adjectives List (NAL) on self-concept, in augmenting the validity of the Basic Test Battery (BTB) for predicting Class "A" enlisted school performance. The three noncognitive tests were administered experimentally to incoming students at seven schools varying widely in curriculum, and to a sample of Submarine School students. Scores were combined with BTB subtests to determine if noncognitive test scores supplemented BTB measures in multiple regression equations. Results indicated that neither the NAPB, NAL, nor HST contributed significantly toward prediction. Further evaluation of these instruments is not indicated.
