This study is a comparison of the average behavioral styles between a group of entering and graduating students in an army officer candidate school. The instrument used is the Job Analysis and Interest Measurement. There is a significant difference in the mean scores between entering (n 561) and graduating (n 319) students in four pre-chosen comparisons established by four hypotheses. Entering students compared with graduating students place a higher value on the approval from others. In the three scales considered by the other hypotheses, the mean graduating students' scores are higher than the entering students' scores. This indicates that: Graduating students as compared with entering students tend to be more self-assertive, are more likely to be persuasive leaders, and are more prone to like supervisory activities.
