The number of service programs offered in the high schools is substantial and appears to be increasing. A survey questionnaire sent to four-year public and private high schools sought information on the development and progress of service programs. The responses to the questionnaire are analyzed and discussed in this monograph. Chapter 1 deals with the philosophy of service programs and the benefits for the young people involved in them. In chapter 2, descriptions are given of the diverse kinds of programs currently in operation in the 1,000 schools that responded to the questionnaire. The programs are varied: some offer academic credit and in some service is a graduation requirement; some emphasize careers while some emphasize altruism. How service progams can augment school curriculum is discussed in chapter 3. Case studies are presented in chapters 4 and 5 of schools with programs that are volunteer only, and schools that require participation in the program. Suggestions are made in chapter 6 on starting or improving a service program in a secondary school. The survey questionnaire showing a tabulation of responses for public high schools used in this study is appended. (JD)
