Assessed longitudinal changes in gender role traditionalism across 4 years of college using national college student data from the 1996 Cooperative Institutional Research Freshman Survey and 2000 College Student Survey. Overall, students' levels of traditionalism declined during college. Women held more egalitarian views than men at college entry and 4 years later. Attitudes were impacted by peers, academic engagement, women's studies courses, and diversity experiences. (SM)
