By using environmental data, possibly as predictors in their own right, but most probably as moderator variables, it was intended to evaluate available and currently used predictors of leadership potential and academic success. The Environment and Interest Inventory was administered to nearly every candidate for admission to the academy. Over 2,000 completed inventories were accumulated, from which 791 of those who actually entered in July 1964 were obtained. The results of the inventory were to be used for the identification of those environment and interest characteristics which were significantly related to any of three criteria: academic standing, aptitude for the service standing, and resignation versus active status. It is found that the typical entrant to the Class of 1968 comes from a family of comfortable means, not wealthy but economically secure. With respect to specific, available artifacts, such as books, cars, etc., there seems to be a high correlation between the availability of such items and the frequency with which they are used. The relationship between availability and utilization is less obvious regarding general facilities and opportunities, such as libraries or community teams. Questions are unresolved regarding "from whom one seeks help with various kinds of problems," since a majority responded "does not apply." (Author/LBH)
