HB 2423 requires Tennessee's state board of education to recognize an advanced degree in media and technology as qualifying for a library information specialist endorsement. It sets specific staffing rules for public high schools (grades 9-12) based on student enrollment: schools with 750-1,500 students must hire a full-time specialist, while smaller schools (under 750 students) must employ a part-time specialist or designate a teacher as a library coordinator. The bill also mandates that someone must supervise students in the library during school hours if a specialist is not present. These requirements take effect July 1, 2026, directly impacting Tennessee public high schools.
