What happened with Lia Thomas?

NCAA championship win (2022)

• Lia Thomas won the NCAA Division I women’s 500-yard freestyle championship in March 2022, becoming the first openly transgender athlete to earn a Division I national title (Wikipedia).
• She was a member of the University of Pennsylvania women’s swimming team from 2021 to 2022 (The Washington Post).

NCAA eligibility policy change (2022)

• In January 2022, the NCAA implemented a new sport-by-sport eligibility policy for transgender athletes, replacing the earlier testosterone-based approach (NCAA.org).
• Under that policy, transgender women could compete if they met sport-specific hormone requirements (NCAA.org).

University of Pennsylvania agreement to block transgender athletes (2025)

• On July 1, 2025, the University of Pennsylvania reached a federal consent decree with the Department of Education, agreeing to prohibit transgender women from participating in women’s sports teams (The Washington Post).
• As part of the agreement, Penn nullified Lia Thomas’s swimming records and reinstated the records of the female competitors she had surpassed (USA Today).
• Penn also sent personal apology letters to swimmers affected by Thomas’s participation (USA Today).

The implication: the NCAA’s 2025 policy, combined with the Penn consent decree, effectively erased the competitive path that Thomas had navigated — and the records she set — under the previous rules.
