Initiative Measure No. IL26-638 concerns participation in athletics at K-12 schools. 

This measure would prohibit students it defines as “biologically male” from competing in certain school athletic activities intended for female students only. It would require verification of biological sex by students’ healthcare providers. 

Should this measure be enacted into law? 

WHAT IT MEANS

Yes

A “Yes” vote would amend Washington Statute to prohibit biologically male students from competing in athletic activities intended for female students only. Students seeking to participate in athletic activities intended for female students only would be required to provide a statement from their healthcare provider verifying their biological sex. 

No

A “No” vote would keep current Washington Statute which does not prohibit biologically male students from competing in athletic activities intended for female students only.   

ARGUMENTS FOR AND AGAINST

Yes

"I-638 will protect fairness in girls’ sports by prohibiting biological men from competing in female athletics.

This measure would uphold title IX by requiring the enforcement of policies prohibiting students it defines as “biologically male” from competing with or against female students in certain interschool athletic activities that are intended for female students only. These requirements would apply to individual or team athletic competitions.

I-638 would ban biological boys from competing in girls’ sports by requiring the student athlete’s doctor to note their gender during their routine sports physical. This initiative protects girls while still ensuring that transgender youth have avenues to compete on an appropriate playing field. 

PROTECT FAIRNESS: Every female athlete in Washington deserves a fair playing field, yet more than 110,000 girls are increasingly required to compete against biological males. 

PROTECT SAFETY: Girls continue to raise legitimate concerns about privacy and safety when required to share locker rooms with biological males under current law, but Governor Ferguson and State Superintendent Reykdal have turned a blind eye. 

PROTECT PROGRESS: Title IX was designed to protect and expand opportunities for female athletes, and ignoring the law threatens to reverse decades of hard-won progress. 

PROTECT THE FUTURE: Allowing biological males to compete in girls’ sports undermines competitive fairness and diminishes the integrity of female athletics statewide. 

PROTECT OPPORTUNITY: Increased participation by biological males in girls’ sports limits scholarships, awards, records, and roster opportunities that Title IX guarantees to female athletes." - Let’s Go Washington   

No

"We all want to protect girls, but I-638 does the opposite by discriminating against girls and putting them at risk of harm. More than 100 doctors agree I-638 will subject girls to invasive, medically unnecessary, and potentially harmful genital exams to verify their sex for sports’ physicals. 

1. I-638 could force invasive genital exams on girls just to participate in elementary, middle or high school sports.

  • I-638 changes the law to require medical sex certification as part of sports physicals for all girls, and bans parents from using birth certificates instead.
  • It could force tens of thousands of Washington girls each year to undergo invasive, embarrassing, and potentially harmful genital exams just to play sports.
  • Free student sports physicals often occur in group settings in gyms, so this invasive exam requirement could subject girls to greater embarrassment and harm. Right now students stay fully clothed during sports physicals, but this could change for girls. 

2. I-638 is the most extreme MAGA measure of its kind in the country and discriminates against girls. 

  • This is the most extreme MAGA measure of its kind in the country because it targets girls with invasive genital exams to medically certify their sex.
  • Boys are completely exempt from this requirement – only girls will be subjected to the medical sex certification and genital exams - putting another barrier between girls and sports. And lawyers say it discriminates against girls, making it unconstitutional in Washington.
  • All girls will be discouraged from playing sports under I-638 because they will be subjected to invasive, embarrassing genital exams. Girls will miss out on the many benefits of playing sports, as well as learning about teamwork and cooperation. 

3. I-638 takes decision making power away from parents, schools, and athletic associations and excludes a tiny group of vulnerable children from sports. 

  • I-638 polices who get to participate in elementary, middle, and high school sports, taking decisions away from sports associations, schools, and parents.
  • This MAGA-backed initiative cruelly singles out trans girls - a tiny, vulnerable minority of students - for exclusion based on misinformation and fear about what it means to be transgender, encouraging harassment, violence, and discrimination.
  • Every child needs to feel supported in becoming who they are. When we exclude children from something as healthy as playing team sports, we increase the risks of isolation, depression, inactivity, and other physical and mental health threats.
  • Banning trans girls from sports is the first step on a slippery discrimination slope against girls who are taller, stronger, less feminine or just unexpectedly better than their peers.” - No Hate in WA State
