When Congress passed Title IX of the Education Amendments of 1972, it transformed the landscape of higher education and K-12 by prohibiting sex-based discrimination in any federally funded program or activity. Early on, the focus of Title IX, including implementing regulations and judicial interpretations, was on ensuring equal opportunities for women in athletics. However, that focus has expanded in recent decades, and the executive branch enforcement emphasis has shifted toward addressing sexual harassment and violence as well as assuring a more equitable learning environment for all students. This timeline explores significant developments in Title IX enforcement and interpretation under the last three administrations, highlighting its evolving role in fostering a safe and inclusive educational experience.
