This study evaluates how grantees of the Office of Adolescent Pregnancy Programs (OAPP) implemented their teen pregnancy and parenting programs and how program participation affected the lives of clients. Chapter I outlines the structure and history of the evaluation project. Chapter II highlights the major client outcomes of OAPP-funded projects and compares these outcomes to data from other sources. Chapter III describes project characteristics, characteristics of clients at project entry and exit, and the types and amounts of services delivered by the projects. Chapter IV describes pregnancy outcomes such as delivery complications and low birth weight for clients who were pregnant when they began participating in the projects and looks at what effects the services given to clients had on those outcomes. Chapter V describes outcomes such as repeat pregnancies, school completions, and welfare dependency for teen mothers, and hospitalization and living arrangements for babies. It also assesses the degree to which projects affected these outcomes. Chapter VI reports on financial data from eight project sites. Chapter VII focuses on the difficulties many projects encountered in becoming fully operational and offers suggestions for avoiding such difficulties. Chapter VIII explores the management and coordination functions of OAPP itself and suggests improvements. Appendices provide detailed financial and service data for eight projects, the summary report forms used by OAPP-funded projects, the indicators of program performance used, and unstandardized statistical data about project outcomes.
