This report describes and documents the experiences of various sponsoring organizations and school districts with Project Follow Through, a national program that promotes alternative educational programs for children in grades K-3. The report is based on field visits and interviews with individuals directly involved in the processes of program approach development and implementation. Information was collected by reviewing written material from both program sponsors and their project sites, by visiting selected sponsors and sites, and by interviewing people who had major roles in the implementation process. Chapter 1 provides an overview of Project Follow Through, and chapter 2 describes sponsor program approaches. Chapter 3 describes Follow Through training procedures and some of the major lessons learned on how to change teacher behavior. Chapter 4 discusses both formal and informal evaluation processes at all levels of Follow Through operation. Chapter 5 describes the process of building administrative support during implementation, and chapter 6 describes the process of designing program approaches and procedures for making them operational in school districts.
