Censorship of school curricula in the United States

Throughout the history of the United States, various topics have been censored and banned in education, including teaching about evolution, racism, sexism, sex education, and LGBTQ+ topics. Due to the federal system of the country being highly decentralized, states are delegated with much of the responsibility for administering public education, and it is often governments of the red states that have enacted such policies.

In 2021, bills were introduced in multiple state legislatures to restrict teaching certain concepts, including critical race theory (CRT) and sexism, in public schools.^[1] Bills were passed in 14 states, all of which had both Republican-majority legislatures and Republican governors.^[2][3] Several of these bills specifically mention "critical race theory" or single out the New York Times 1619 Project. CRT is only taught at a university level, though some lower-level curricula have reflected basic themes of CRT.^{[4][5][examples needed]}

Other state-level efforts have involved state boards of education restricting the teaching of issues surrounding race and sex.^[6]
