Those committed to the multicultural transformation of the psychology profession must become familiar with ways to initiate and maintain this challenging process. The efforts of a graduate training program to sustain its multicultural evolution are presented along with longitudinal outcome data. Over time, diversity interventions were seen as more effective while differences in the success ratings among students of color and their White peers decreased. Reports of having heard about, seen, or experienced prejudicial behavior, however, remained unchanged. The institutionalization of multicultural change procedures, the revision of assessment instruments for long-term use, and the potential benefits of comparative diversity research are discussed.
