The Washington Tribal Education Sovereignty then Justice Toolkit is designed to support Tribal leaders engaging in consultation and government-to-government communication with local and state education agencies. The toolkit includes: Part 1: Applying educational Sovereignty as a strategy to construct Tribal plans toward educational justice for future generations. In this section, explore example target goals of educational Sovereignty, reflect on the historical events and policies that have shaped Indian education over the past 150 years, and read about five Indigenous theories shaping education. Part 2: Detailing K-12 school systems, structures, leadership models, and funding sources. In this section, learn more about structures, policies, and process in public K-12 school systems that impact Native students, including key practices around demographic data collection and funding. Part 3: Framing guiding questions for Tribes to ask K-12 schools prior to Tribal consultation and government-to-government gatherings. In this section, consider guiding questions to ask school districts responsible for the education of your Tribal citizens and implement meaningful consultation protocols and procedures. Part 4: Accessing resources for best practices by other Tribes, Indian education organizations, and national leaders. In this section, review resources and become familiar with the Every Student Succeeds Act (ESSA) terms used in government-to-government consultation with school districts. Parts 5-7 offer references, a glossary, and information about consultation beyond ESSA.
