In this study the author surveys social studies standards from 14 U.S. states seeking to answer: (a) what social studies knowledge about American Indians is deemed essential by those states mandating the development of American Indian Education curricula for all public K-12 students? and (b) at what grade levels is this social studies content knowledge mandated in public K-12 schools? Document analysis, open-coding, and constant comparison revealed that the knowledge states standards require can be organized into six themes: identification/classification of tribes, distinct tribal cultures, contributions to mainstream U.S. culture, tribal government, connection to environment, and economics/occupations. The findings also revealed that the majority of standards relating to American Indians are directed to elementary grade levels. Standards in only two states, Maine and Montana, cover a breadth of curricular content and require that content coverage to continue K-12.
