This inservice training program, which was developed for the improvement of school library media programs, is designed for library media specialists, administrators, and teachers. Tailored to meet particular school district needs, the program permits extensive on-site inservice training lasting from three days to two weeks. Using various procedures such as checklists and committee meetings with educators, problem areas were identified and clustered into four components: (1) long range planning; (2) the library media collection; (3) organization and arrangement of the library media center; and (4) staff utilization. Training activities and a learning module were developed for each area. This manual includes guides for the program director and trainer personnel, as well as the detailed modules. These materials were utilized by the inservice training specialists at on-site sessions involving library media personnel, classroom teachers, and administrators from 42 schools selected from the 175 initial requests for participation in the field testing of this program. Post-visit reports by the specialists indicate many changes in existing media programs as a result of the inservice project. The results of this project will be published by the U.S. Office of Education as a model program. (Author/RAA)
