Education Northwest partnered with the Region 16 Comprehensive Center to gather information on efforts and supports that reflect best practices in Indigenous school improvement. The authors carried out the study in two phases. First, they conducted a literature review of relevant documents including empirical articles, white papers, statements of research results, and other artifacts demonstrating exemplary uses of effective schooling practices for Native American/Alaska Native students. The authors specifically focused on evidence generated by and with Indigenous researchers and educators. Second, they conducted outreach to experts in the fields of school improvement and Native education to gain their perspectives on successful, evidence-based approaches to develop?schools that holistically support Native American/Alaska Native students. The authors recruited and interviewed 11 individuals across the country with first-hand knowledge of implementing Indigenous pre-K-12 school improvement models. This report summarizes findings that address two research questions: (1) What can school improvement models founded in Indigenous ways of knowing or grown out of Indigenous communities look like? and (2) How can these findings inform ongoing and future work in Washington State?
