This effectiveness review of the California Literacy Campaign (CLC), a program designed to significantly reduce the number of functionally illiterate adults in California, was submitted to the California State Library for consideration of continuation of state funding beyond 1984-85. The review includes an analysis of existing data (state library directives, guidelines and criteria, and second-quarter reports of the 27 funded projects in public libraries); telephone interviews with a sample of adult literacy students; and a written questionnaire survey of a sample of tutors. This evaluation incorporated a modification of the discrepancy model which compares a program's performance to the standards set for its performance. The analysis of existing data was conducted in three steps: all standards, goals, and outcomes set for the campaign at various stages in its first two quarters of development were reviewed, refined, and organized into major program outcomes and processes; all available data were analyzed to determine discrepancies between intended and actual outcomes; and implications and recommendations for improvements were generated. Following an introduction which covers background, overview, study design and execution, a review of the literature, and definitions, the report is divided into four sections and appendices. They include: (1) The Adult Literacy Students; (2) The Tutors; (3) The 27 Library Literacy Projects; and (4) The Work of the California State Library. A CLC project locations map, the student interview guide, the tutor questionnaire, and the library literacy project directors' questionnaire are appended. (THC)
