Increasingly, policy measures are emerging at national or agency level in different countries to improve the lot of children in state care. Most of these rely heavily on social workers for their implementation. Yet the capacity of social workers to carry out such an ever increasing range of complex tasks seems never to be properly recognised as an issue. This paper argues, from an international perspective, that the continuing central role of social work in the lives of children in care merits much more emphasis in policy and service delivery. The nature of the increasing demands on social workers in this area of work are explored. Possible strategies to help build the capacity of social workers to respond to the needs of children in state care in the new millennium are discussed. Such capacity building necessitates government and agency initiatives to ensure realistic staffing levels, renewed training, and adequate support for social work services to children in state care.
