What is critical race theory, and why do Republicans want to ban it in schools?

The latest front in the culture wars over how U.S. students should learn history and civics is the concept of critical race theory, an intellectual tool set for examining systemic racism. With roots in academia, the framework has become a flash point as Republican officials across the country seek to prevent it from being taught in schools.

In reality, there is no consensus on whether or how much critical race theory informs schools’ heightened focus on race. Most teachers do not use the term “critical race theory” with students, and they generally do not ask them to read the work of legal scholars who use that framework.
