Reading Is Fundamental (RIF) is a national program that seeks to motivate children to read. Implemented by local sponsors and aimed at disadvantaged groups, it offers participating children a wide selection of attractive paperbound books about interesting people, places, and events. The multisite evaluation discussed in this technical report studied children, their parents, their teachers, and the RIF delivery agents in six cities in different parts of the nation. The evaluation focused on both the outcomes of the program and its operating processes. Matched samples of fifth graders and second graders, half of whom were attending RIF programs and half were not, were interviewed and tested in the study. Instrument development, analysis, and results are discussed in detail in this report. Copies of the instruments used, instructions to the interviewer, and the process evaluation are included as appendixes. The evaluation, which found that RIF students exhibited more positive feelings about being in the presence of books, was generally favorable to the RIF program. (AA)
