The document summarizes research on the impact of school library media programs (SLMPs) on student achievement. Several studies found that strong SLMPs that provided students with skills like fluency, comprehension, vocabulary, and independent reading positively affected 99% of students' academic achievement, as measured by higher test scores. Characteristics of effective SLMPs included collaboration, principal support, flexible scheduling, access to technology, treating the librarian as a teacher, support staff, developed collections, community relationships, extended hours, and reading motivation programs.
