The increasing diversity of the populations encountered and served by child welfare workers challenges cultural competence models. Current concerns focus on the unintentional over-emphasis on shared group characteristics, undervaluing unique differences of individuals served, and privileging worker expertise about the client's culture, thereby exacerbating the power imbalance between them. This article promotes cultural humility in child welfare service delivery as a compliment to cultural competence, to liberate workers from expectations of cultural expertise about others, and to actively engage the clients, inclusive of their cultural differences, in the service delivery process. Skills and practice principles are discussed. (Contains 1 figure.)
