Designed to help library media personnel analyze their local programs to identify strengths and weaknesses and then to progress toward specific goals, these recommended standards address all aspects of library media service within Illinois schools. Standards are included for three phases of development representing increasing growth and achievement. Quantitative measures of staff, facilities, and materials are included as well as qualitative aspects suggested under program and service. Recommended standards for district-level media services are followed by a discussion of special considerations for low-enrollment school districts. An assessment guide for evaluating the media library program is provided, with space included to state short-term and long-term goals in each area addressed by the standards. Appendices include a statement on instruction in the use of libraries, a statement on media programs by the Illinois Program for Evaluation, Supervision and Recognition of Schools; and a resolution adopted by the Illinois State Board of Education in support of a national library and information services network.
