Tania Otero Martinez writes: “Since a shocking plunge in math and reading scores on the latest National Assessment of Educational Progress, educators, administrators, and policymakers have grappled with how to address learning challenges following the pandemic. One factor that has largely escaped notice, however, is the role school libraries and librarians play in academic performance. School libraries are too often treated as a luxury rather than an essential part of the public education system with a proven impact on learning. It is time to turn around years of disinvestment in school libraries and librarians.”
