Standards-based education reform efforts that began in the 1990s resulted in social studies standards by grade level in every single state, stretching from kindergarten to grade 12. All of these standards single out history as a separate subject or strand, and many include world history as a subset within history as a whole. These standards are highly variable, idiosyncratic, and sometimes error-ridden, and they have been the source of enormous controversy. Some world history standards are completely skills-based, with only one sentence about content, and many are very Eurocentric, especially in the lists of individuals and events students should know. Recent efforts to develop better standards, such as the C3 Framework, have become embroiled in the controversy over Common Core, but because high-stakes testing is often based on state standards, world historians should get involved in improving them, and advocate for better world history teaching.
