This qualitative study explored the experiences of self-identified White students currently enrolled at a predominantly White institution who were cross- racially involved for at least ten weeks in a multicultural association, club, or organization that had students of color as the racial majority. This study also examined students' consciousness of Whiteness and the development of students' White identities based on their cross-racial experiences. Utilizing a sample of 4 students in concert with a review of relevant literature, the principal findings of this research are that cross-racially involved students have heightened awareness of difference based on race, including their own White racial identity. Although racial tension exists between individuals' White identities and the collective organization’s multicultural identity, White students who were more deeply involved in multicultural organizations indicated that they (a) had a higher sense of belonging with their peers of color, (b) became more conscious of their Whiteness both inside and outside of their multicultural organizations to a certain degree, and (c) desired to more completely understand their ethnic heritage. Findings from this study can contribute towards literature on the development of racial justice allies in college. In order to influence racial justice ally development at a predominantly White institution, findings from this research suggest that student affairs administrators should encourage White students to engage in multicultural organizations so they can understand how their Whiteness "shows up" for others including the impact of privilege and oppression in a multicultural society.
