K-12 curriculum is primarily a state and local matter, but national debates have intensified over:
- Reading: The "science of reading" movement's push for phonics-based instruction over balanced literacy.
- Math: Common Core, conceptual vs. procedural emphasis, tracking debates.
- History and civics: How to teach American history including slavery, civil rights, founding documents, and current controversies.
- Race and gender content: Critical race theory bans, transgender-related curriculum, parent-notification rules.
- Parent rights: State laws expanding parental access to materials, opt-outs, and book-challenge processes.
Federal influence is limited (the Department of Education cannot dictate curriculum) but conditional grants, civil-rights enforcement, and Title IX shape state behavior.
