Over the past year, sweeping local and state-wide policies framed as bans against "CRT" are being propagated to restrict how race and racism can be taught in K-12 schools across the nation. As a result, schools are increasingly becoming a place where teachers face interpersonal and professional risk for teaching about US racial realities, including threats to their professional licenses for engaging historical or current day topics of race, inequity and injustice. In this article, we first draw on CRT to analyze how CRT-bans leverage white defensiveness and white comfort to restrict instruction and discourse about systemic racism, thereby upholding it. Second, we describe a mixed methods research study with 117 teachers across the US that provides an initial look at how teachers are being harmed by these bans. The data suggests that CRT-bans are negatively impacting the racial climate of schools and contributing to the systematic pushout of teachers, particularly those committed to equity and inclusion. In addition to capturing teachers' experiences about the bans, we specifically examine the pressure teachers are experiencing and its exacerbation of an already national problem, teacher attrition. We end the article with evidence-based recommendations on ways schools might mitigate the harm of CRT-bans on teachers.
