The Education Department announced Monday it has formally rescinded the Biden-era Title IX interpretation that gave sex-based discrimination protections to students on the basis of sexual orientation and gender identity.

Schools now must go back to the Title IX code as held under the previous Trump administration in 2020, which the department says will protect women’s sports.

“Thanks to today’s action, the published Title IX regulations faithfully reflect court orders and Congressional intent — reducing confusion for parents, students, and educational institutions. We will continue to relentlessly champion equal opportunity for all Americans and hold accountable any school or college that violates the rights, privacy, or athletic opportunities of our women and girls,” Education Secretary Linda McMahon said.

The Biden-era Title IX rule was already struck down in the court system after challenges from Republican states.

And the administration has pursued its own definition since President Trump returned to office, making deals with schools such as the University of Pennsylvania to take transgender athletes out of their women’s programs.

Opponents of the move say it will harm transgender athletes and weaken protections for sexual assault victims.

“Sexual harassment and assault continue to be pervasive in schools and, to the fullest extent possible, we should be working to enforce the laws that protect student survivors of sexual violence. Yet, Education Secretary Linda McMahon and the Trump administration have decided to ignore what survivors need, instead weaponizing Title IX to attack trans students,” said Shiwali Patel, senior director of education justice at the National Women’s Law Center.
