@rimugu Federal dollars going into schools (potentially including charters via vouchers) should mean that the federal gov't (DoE) should be able to mandate some, not all, standards. Example, TX is the second largest textbook market. A decision to omit evolution or downplay slavery/segregation can affect other schools hoping to take advantage of economies of scale.

Data driven teaching should be an important part of determining curriculum (e.g. phonics vs whole language reading).
