An institutional commitment to educating a diverse student body is most compelling when it is broadly defined and connected to the educational mission, different levels of institutional practice, and systematic research on student educational outcomes. This study examines how structural diversity and intentional educational practices involving diversity influence students' development of a pluralistic orientation during the first two years of college. The results highlight similarities and differences across four racial/ethnic groups, and the study concludes with implications for scholars and multicultural practitioners interested in assessment.
