The National School Library Standards require school librarians to make equity a value that permeates the entire school library community. Creating displays to celebrate diversity is not enough. We cannot allow ourselves to approach diversity as a "social good," in which isolated programs serve marginalized students without challenging the overall structures of oppression (Watt 2015, 9). Instead, the AASL Standards challenge us to embrace the systemic value of diversity as we work to remedy structural barriers to equity. This focus on systemic equity is also in line with efforts to include school library communities, collections, and curricula in the Every Student Succeeds Act (ESSA). This 2015 reauthorization and expansion of long-standing education policy and civil rights law renew our focus on equitable opportunities for all students, and libraries are part of this vital work. The AASL Standards are organized into six Shared Foundations; the authors explore each through the lens of equity, providing a rationale for action and examples of school library practice.
