This purpose of this guide is to provide qualitative criteria for assessing school library media programs and to furnish a resource for developing and/or improving school library media programs. The intent is to meet the needs of diverse school systems and give direction for implementing library media programs while offering a viable evaluation tool. A major focus of this revision is to provide a plan that emphasizes the individual need of each school, its library media center, students, and teachers. The guide stresses that successful implementation requires that the library media specialist form a partnership that involves students, teachers, administrators, and families and makes links to the community. The guide includes seven basic components: (1) Program Standards; (2) Preparation of Library Media Personnel, Certification, and Continued Education; (3) Learning & Teaching; (4) Program Administration; (5) Personnel and Evaluation; (6) Library Media Resources and Equipment; and (7) Facilities. The appendix contains AASL (American Association of School Librarians) position statements, taxonomies, a directory of organizations, a glossary, the Library Bill of Rights, and a list of online resources. Includes an index. (Contains 31 references.) (MES)
