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.
