Researchers have proven that a quality school library program with a certified school librarian who teaches information literacy skills to students improves academic achievement. Conducted over the past 30 years and 22 states, these statewide studies examined students’ standardized reading test scores and other indicators of student learning and correlated them to components of school library programs.

The Background on the School Library Impact Studies
Begun in the early 1990's by Dr. Keith Curry Lance and his associates at the Colorado Department of Education and the University of Denver, these reports primarily correlated standardized language arts test scores of students to components of school library programs, such as staffing, budgets, collections, etc. To date, 23 states and one Canadian province, Ontario, have conducted similar research by a variety of researchers.
