Higher test scores linked to certified media specialists
Preliminary findings of research show a statistically significant increase in the ELA test scores—almost a 10 point difference—among fourth-grade students whose schools had certified librarians over students in schools without certified librarians. Certified librarians are also more likely to provide students with materials that present more diverse points of view and that better support the curriculum than non-certified librarians.
