This study examines the actual and the desired performance of school librarians in areas of planning, accessing networks, instructional and curriculum development, and production of learning resources. A questionnaire based on the 1976 certification requirements for Texas learning resources specialists was constructed as the survey instrument. Research problems were tested according to two principal criteria: (1) perceptions of superintendents, principals, and librarians, and (2) the size, location and level of selected school districts. Based on data analysis, this report concludes that: (1) all three major groups of respondents agree on the gap between perceived actual versus ideal conditions; (2) librarians' responsibility for selection and acquisition of audiovisual materials receives less recognition than their responsibility regarding print materials; (3) librarians do not fully participate in management and planning activities; (4) the size of the school district affects the librarian's service and management functions; (5) librarians are not accepted in the instructional role; (6) librarians' access to resources is limited within the school district; (7) communication between librarians and administrators is lacking. These findings are generalizable to a wider population. (SC)
