This article describes the Consortium for Social Work Training in Aging (CSWTA), a unique partnership among 3 schools of social work and 6 county departments of adult and aging services. Using an innovative collaborative training model that included structured rotations and curricular support, CSWTA contributed to increased student interest in aging, improved knowledge about aging and aging services, and enhanced training capacity of county departments of adult and aging services. This model represents a promising approach for increasing the number of professional social workers trained to provide effective service and leadership to the public sector in the field of aging.
