Almost 90 percent of social studies curriculum standards do not mention American Indian and Alaska Native (AI/AN) history after 1900, and 27 states do not mention AI/AN peoples in their K-12 curricula at all. AI/AN content and contributions are even less prevalent in English language arts standards, with most states not yet meaningfully referencing, representing, or reflecting AI/AN cultures, philosophies, or contributions in their standards. Incorporating the histories, cultures, and contributions of different populations in state standards supports academic achievement and social-emotional learning for students of all backgrounds. Diverse curricula can also help students learn about different cultures and perspectives, which promotes the attitudes, knowledge, and skills needed to join a global workforce. To increase inclusion and amplify the contributions of AI/AN peoples, WestEd's Region 13 Comprehensive Center developed this tool. It is designed to help state education agencies incorporate high-quality, authentic AI/AN content into their English language arts standards review and revision processes to support learning for all students.
