“This study found that students were more likely to meet or exceed English Language Arts and Literacy (ELA) standards when their schools had credentialed teacher librarians (TLs), TLs serving a single school, and school library staff who engaged in certain specific activities, including managing their library collections and supporting literacy teaching. With rare exceptions, relationships between library staffing levels and staff activities and ELA performance levels persisted regardless of the gender, race/ethnicity, or socioeconomic status of students.” (Lance & Gerrity).
