This technical guide is a training tool to help members of Head Start governing bodies, policy groups, agency directors, and Head Start and Early Head Start directors understand their responsibilities in a Head Start environment that emphasizes shared decision-making. The guide offers a framework for clarifying expectations and provides concrete, practical information that can be used in the context of a local agency's unique history, issues, resources, and priorities. The guide contains the following modules: (1) "Understanding the Role of the Governing Body"; and (2) "Using the Tools of Governance in Shared Decision-Making." Both modules begin with activities to introduce the basic concepts; remaining activities are designed to allow all participants to clarify and practice skills. Each module contains "outcomes,""key concepts," and "background information." The final sections of the guide contain activities for participants to apply the skills learned to their own programs, and a list of about 52 annotated resources for further information on module topics.
