The dissemination and adoption of new standards is of primary concern to national education associations, the American Association of School Librarians (AASL) among them. The purpose of this content-analysis study was to investigate the impact of the National School Library Standards for Learners, School Librarians, and School Libraries (AASL 2018) on the School Leader Collaborative members' understandings of and advocacy for the roles and responsibilities of school librarians. These members were all public school administrators. The researchers used documents co-developed by AASL and the Collaborative to create a category matrix to analyze the content of primary and secondary source videos. The results of the study show the extent to which these exemplary administrators value leadership and other responsibilities of school librarians. Their perspectives offer practicing and preservice school librarians specific expectations to elevate the practice of school librarianship and improve library services for all library stakeholders.
