Despite the growing body of literature focused on diversity management and its implications for career experiences and perceptions, team dynamics, customer service, and other dimensions of organizational performance, a significant gap remains. To address the gap, this article reviews the managing diversity literature published between January 2000 and December 2005 to identify the subset of the literature that examines the effectiveness of specific diversity interventions implemented in organizations. Only 38 such studies were identified. We conclude that the current evidence base provides limited guidance to human resource professionals as they design and implement diversity interventions. Each study identified in the review is categorized by research methodology and by type of intervention: diversity training and education; mentoring; and other organizational development interventions. Characteristics of effective interventions are identified. Gaps in the literature and areas for future research are described. (Contains 4 tables and 1 figure.)
