This article provides a detailed review of the historical and theoretical context in which culturally competent practice has evolved in the social work profession and enables educators and practitioners to see holistic connections between the past and present. Historical review of the inclusion of diversity content is followed by definitions of culture, cultural competence, and culturally competent practice. We then provide a synthesis of different frameworks currently being used for understanding the development of cultural competence in psychology and social work, and conclude with discussion and implications for social work education and practice.
