This study sought to determine the extent to which students' development of internal locus of attribution for academic success during the first year of college was influenced by institutional characteristics, students' academic experiences, and their social/nonacademic experiences. The sample was 2,392 first-year students attending 23 diverse two-and four-year institutions located in 16 states throughout the country. Controlling for precollege internal attribution, academic ability, and other potentially confounding influences, a number of variables had significant, net, positive associations with end-of-first-year internal attribution. These included attending a two-year (versus a four-year) college, level of exposure to postsecondary education, work responsibilities, the extent of course organization, instructional clarity, and instructor support in the teaching received, and participation in intercollegiate athletics. Additional analyses indicated that many of the associations with internal attribution were conditional rather than general, differing in magnitude for different kinds of students.Unique and innovative minds grow among those who can come to perceive differences between others and themselves, and who continue to hold the assumption that they are free agents, the makers of their own fate (Lefcourt, 1982, p. 2).Independence of thought and action has long been considered not only an important element in conceptions of adulthood and psychosocial health (e.g.,
