The original law, officially 20 USC 1681 - 1688, was a portion of the United States Education Amendments of 1972. It reads
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.
Because the wording of Title IX is very brief, it has been necessary to add clarifications since its implementation. In 1988, a clarification was made that any educational institution that received any federal funding had to be in compliance. In 1994, the Equity in Athletics Disclosure Act required institutions receiving federal assistance to make disclosures about their athletic programs for both men's and women's teams. In 2002, the law was renamed the Patsy Mink Equal Opportunity in Education Act after Patsy Mink, the U.S. House co-author and sponsor. Amendments were made in late 2006 that made it easier for primary and secondary institutions to operate single-sex classes and extracurricular activities. More recently, clarifications were made that protected transgender students by requiring their schools to treat them in keeping with their gender identities. These clarifications were not legally binding, however, and have since been rolled back.
