The Biden administration proposed new regulations under Title IX Thursday to make it illegal for schools to impose blanket bans on transgender students playing on sports teams that align with their gender identity. Schools could, however, still bar transgender students from participating in competitive high school and college sports, if deemed necessary to maintain “fairness in competition” after evaluating the sport, the level of competition, and the grade or education level involved. Twenty states currently have blanket bans on trans student athletes.

Meanwhile, the Supreme Court ruled Thursday in favor of a 12-year-old transgender girl in West Virginia, allowing her to continue competing on her school’s girls’ track and cross-country teams while a lawsuit over a state ban proceeds.
