Title IX, which was part of the Civil Rights Act of 1964, became a law in 1972 to communicate to schools that they needed to provide women with equal opportunities to men in all educational programs, including joining sports teams. This was communicated through the law Title IX in order to enforce the changes for women in schools, such as being able to join the high school basketball team and receive scholarships.
Title IX states that "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." This includes school sports along with clubs and school courses from elementary to colleges and universities.

Title IX was introduced into congress by Senator Birch Bayh and Representative Edith Green. It was signed by president Richard Nixon into the Education Amendments of 1972. Representative Patsy Mink wrote the laws and introduced them to Bayh. Although Title IX helped all female athletes and students, it did not benefit any women working in educational institutions.
