Across American campuses, racial tension and other issues of diversity remain a major challenge. The majority of this country's institutions demonstrate that they value and promote diversity through efforts in affirmative action, minority student and faculty recruitment, minority retention, administration of special scholarships, diversity Web sites, diversity centers, and ethnic study programs. Most colleges and universities also identify diversity as a priority in their mission and core value statements. Despite continued institutional support for diversity issues, racial tensions remain very much in evidence. According to the Southern Poverty Law Center, college campuses are the third most common place for hate crimes to occur. In this article, the author discusses the importance of student racial climate and one student-based approach--Sustained Dialogue--to improve this climate on college campuses in the United States. Sustained Dialogue, a carefully defined but open-ended process that focuses on changing relationships that are strained along ethnic, racial, religious, or other lines, offers a safe environment for students to come together to explore relationship dynamics.
