This report details the theoretical framework, methodology, and findings of research into the impact of Parent Advisory Councils (PACs) on the management and administration of Title I programs at the local level. The eight school districts studied were selected because they varied in their orientations toward PAC involvement in Title I, and in geographical location, urban/rural character, and local education agency (LEA) size. Chapter I provides an introduction. Chapter II contains a description of the theoretical framework underlying the study. In Chapter III activities related to data collection are described. Included in the discussion are descriptions of the sample of school districts and respondents within them, data collection instruments, data collection procedures, and issues surrounding the interpretation of data. Chapter IV presents the study's findings. These findings are organized around the theoretical framework set forth in Chapter II; discussion thus focuses on the impact of PACs, PAC activities, PAC membership, characteristics, PAC responsibilities, recruitment of PAC members, external constituencies of PACs, and LEA and state education agency orientations toward PACs. In Chapter V the conclusions and implications of the findings are elaborated. Volume III of the study consists of three appendices. Appendix I documents the study's instrumentation. Appendix II shows in tabular form the variations in responses to questions contained in the interview schedules. Finally, appendix III provides 67 tables of statistical data to support the findings detailed in volume I. (RDN)
