This paper describes the implementation of a Head Start Family Service Center (FSC) program and discusses the impact of such centers on Head Start preschool education. It reviews the role of current Head Start FSCs on the provision of support services to Head Start families, especially in the areas of adult literacy, substance abuse education and counseling, and career development and employment. It then describes the services provided by the Southern Ute Head Start Family Center in Ignacio, Colorado, and their effects on family mental health and family environment. Finally, the paper presents data on the overall effects of family-focused Head Start programs such as FSCs, showing that annual reports from the Southern Ute site and other FSCs indicate substantial positive changes in families who are enrolled in FSCs.
