The structure and function of family literacy programming in Illinois is examined in this two-part report. National models are reviewed to provide an understanding of research and practice in the field, and a framework is proposed for the systematic development and evaluation of family literacy programs. Based on visits to 19 sites (59% of the identified programs in Illinois) serving nearly 1,500 families, programs were found to have diverse characteristics in terms of students, philosophy, and funding. All contained an educational component. Eight model programs are identified, each falling into a "networking" or "center-based" working structure. Criteria for program evaluation are summarized in part 1 and further discussed in part 2. Eleven recommendations are given for program effectiveness, such as including both students and teachers in planning, incorporating evaluation strategies into program design, providing staff development services, and including networking mechanisms. The site visit questionnaire and program descriptions are appended in part 1; part 2 appendix contains examples of locally developed instruments, including some in Spanish. The report contains 36 references and an annotated list of approximately 150 additional program resources, including those for children. (Adjunct ERIC Clearinghouse on Literacy Education) (LB)
