Since its beginning in 1965 as a part of the War on Poverty, Head Start's goal has been to boost the school readiness of low-income children. Based on a 'whole child' model, the program provides comprehensive services that include pre-school education; medical, dental, and mental health care; nutrition services; and efforts to help parents foster their child's development. Head Start services are designed to be responsive to each child's and family's ethnic, cultural, and linguistic heritage. The Congressionally-mandated Head Start Impact Study was conducted across 84 nationally representative grantee/delegate agencies. Approximately 5,000 newly entering 3- and 4-year-old children applying for Head Start were randomly assigned to either a Head Start group that had access to Head Start program services or to a non- Head Start group that could enrol in available community non-Head Start services, selected by their parents. Data collection began in fall 2002 and is scheduled to continue through 2006, following children through the spring of their 1st-grade year. The study quantifies the impact of Head Start separately for 3- and 4-year-old children across child cognitive, social-emotional, and health domains as well as ii on parenting practices. This book is essential reading for those in the education field.

On its 30th anniversary, public acceptance of Head Start is high, yet understanding of its goals is low, and evaluation research is limited in quality and scope. In this book, a roundtable of representatives from government, universities, medicine, and family support agencies identifies a set of research possibilities to generate a broader understanding of the effects of Head Start on families and children. Among the important issues discussed are the ethnic and linguistic diversity of Head Start families, the social conditions of the community context, and the implications of the changing economic landscape for both families and Head Start itself.
