OCR has consistently reaffirmed that the Federal civil rights laws it enforces protect students from prohibited discrimination, and are not intended to restrict expressive activities or speech protected under the U.S. Constitution’s First Amendment.

The fact that discriminatory harassment involves speech, however, does not relieve the school of its obligation to respond if the speech contributes to a hostile environment. Schools can protect students from such harassment without running afoul of students’ and staff First Amendment rights. For instance, in a situation where the First Amendment prohibits a public university from restricting the right of students to express persistent and pervasive derogatory opinions about students with a particular type of disability, the university can instead meet its obligation by, among other steps, communicating a rejection of stereotypical, derogatory opinions and ensuring that competing views are heard. Similarly, educational institutions can establish a campus culture that is welcoming and respectful of the diversity all students and institute campus climate checks to assess the effectiveness of the school’s efforts to ensure that it is free from harassment. Schools can also encourage students on all sides of an issue to express disagreement over ideas or beliefs in a respectful manner. Schools should be alert to take more targeted responsive action when speech crosses over into direct threats or actionable speech or conduct.
