This guide is a planning tool for establishing Head Start-Parent Teacher Association (PTA) partnerships, building effective transition practices from preschool to kindergarten, and promoting continuity in parent and family involvement. Designed for use by coordinators of early childhood, parent involvement, and outreach activities, the guide can be used to facilitate planning meetings to promote Head Start partnerships with the PTA or elementary schools, to assist in developing joint transition activities, and to enhance planning efforts when designing parent and family programs and services. The guide includes "how-to" tips; best practices identified from Continuity for Success pilot sites in New York, North Carolina, and Texas; lessons learned throughout the partnership between Head Start and the PTA, current research findings on child and family transitions from preschool to kindergarten, and tools developed through National PTA and other sources. The guide is organized into four parts: (1) "Continuity for Success: A Partnership Between National PTA and the National Head Start Association"; (2) "How to Establish Partnerships"; (3) "Building Effective Transitions"; and (4) "Measuring Increases in Parent Involvement." Forms such as activities checklists and evaluation tools are appended. (KB)
