Despite claims to the contrary, K-12 educators are applying the racial prejudice of critical race theory (CRT) to school lessons. In recent months, parents and policymakers around the country have objected to CRT's mischaracterization of American history in the academic subjects of history and civics. Critical race theorists, however, have also applied the theory's racially biased principles to math and science. Some educators have redesigned math and science curricula to incorporate CRT's racially discriminatory ideas to these technical subjects, replacing a focus on mastery of mathematical and scientific processes with racial bias. Parents, educators, and policymakers should reject racial prejudice in every subject, and educators and policymakers should prohibit any instructional material from requiring children to affirm, believe, or practice racial discrimination in their schoolwork.
