The number of school librarians has been shrinking in the past few years in part due to the lack of evidence linking them to student achievement. Building on a foundation of correlational studies linking school librarians with student achievement, this study uses a quasi-experimental design that mimics random assignment to treatment and comparison groups through application of a matching technique. Restricted data from North Carolina and propensity score matching was used to compare students who attended school with a full-time certified school librarian to similar students who did not attend schools with a full-time certified school librarian. In addition, this relationship for both reading and math over a four-year time span was examined. Findings include that students who attend schools with a full-time certified librarian score significantly higher on math and reading tests than do matched students who attend schools without a full-time school librarian.
