Critical race theory (CRT) is a theoretical framework in the social sciences focused upon the application of critical theory, a critical examination of society and culture, to the intersection of race, law, and power. By 2002, over 20 US law schools and at least 3 law schools in other countries offered critical race theory courses or classes which covered the issue centrally. Critical race theory is taught and innovated in the fields of education, political science, women's studies, ethnic studies, and American studies.
