The impact of selected aspects of the collegiate experience on changes in undergraduates' occupational preferences and personal goals is examined in this study. Two aspects of the college environment are assessed: the social structure and the students' perception of the institution's ability to facilitate the attainment of personal goals. The joint effects of family background, family socialization, and experiences at college on career choices are closely examined. Data were compiled from several national surveys of students and faculty in American colleges and universities. Undergraduates from 72 different institutions and majoring in either English, mathematics, history, or political science were surveyed. The academic department is viewed as an important influence on both faculty and students. Multiple regression analyses are provided for each major field by sex with prestige of upper division career choice as the dependent variable. Results indicate that the single most important predictor of career prestige aspirations was the prestige of the occupation to which upper division undergraduates aspired at entrance to college as freshmen. Faculty seemed to be more influential with respect to students' values than career aspirations. The results indicate the importance of examining conceptually defined organizational units when studying college impacts on career aspirations. (Author/SF)
