Arizona · November 2026 general election · Legislative referral · Election day November 3, 2026
Topics: Sports and athletics, Civil rights, Education
In plain language
Proposition 318 would enact a state statute requiring schools and athletic associations to restrict access to restrooms, locker rooms, showers, and similar private spaces according to the sex recorded on a student's original birth certificate, and would bar students recorded male at birth from participating on female-designated athletic teams. The Legislature referred the measure, styled by supporters as the Protect Girls Sports in Arizona Act, along party lines, with Republicans unanimously in favor and Democrats unanimously opposed. Former Arizona Treasurer Jeff DeWit serves as honorary co-chair of the campaign supporting it.

What supporters say
- Supporters of the Protect Girls Sports in Arizona Act, including honorary campaign co-chair and former state Treasurer Jeff DeWit, argue that allowing transgender girls to compete on girls' teams causes cisgender girls to lose competitive and scholarship opportunities.
What opponents say
- LGBTQ advocacy groups organizing against the measure say it addresses a problem that data does not support: the Arizona Interscholastic Association, which oversees more than 170,000 student athletes statewide, approved only 16 applications from transgender students to play on a team consistent with their gender identity between 2017 and 2022, when the state's current athletic ban took effect, with about half of those from transgender girls.
