This study addressed two questions: (a) Do different forms of campus racial diversity contribute uniquely to students' learning and educational experiences when they are simultaneously tested utilizing multilevel modeling? (b) Does a campus where students take greater advantage of those diversity opportunities have independent positive effects on students' learning? Consideration of racial diversity extended beyond student composition and included social and curricular engagement. Results suggest that benefits associated with diversity may be more farreaching than previously documented. Not only do students benefit from engaging with racial diversity through related knowledge acquisition or cross-racial interaction but also from being enrolled on a campus where other students are more engaged with those forms of diversity, irrespective of their own level of engagement. . Her areas of interest include diversity (at both student and faculty levels), diversity-related initiatives in higher education, campus climates, and the impact of higher education on student development. As a graduate student, she became increasingly interested in diversity-related issues in higher education, a topic in which Mitchell J. Chang is an expert. She hopes that this paper will contribute meaningfully to the research supporting the educational benefits of diversity.MITCHELL J. CHANG is a professor at . He specializes in the study of higher education, with an emphasis on campus racial climate, educational access, and opportunity. The controversy over race-conscious admissions practices has been the focus of his research for over a decade. He was amazed by the lack of empirical evidence steering the 5th District Federal Court of Appeals ruling on Hopwood. It turned out that some of the claims made by the courts also made for a rich research agenda.
