Title IX is a landmark federal civil rights law that prohibits sex discrimination in education. Title IX is not just about sports; it is a prohibition against sex-based discrimination in all educational or school-sponsored programs.
Title IX states:
No person in the United States shall, on the basis of sex, be excluded from participation in, be denied the benefits of, or be subjected to discrimination under any education program or activity receiving Federal financial assistance.
