Last week, dozens of Colorado school board members and administrators issued an open letter to the Colorado High School Activities Association (CHSAA), making what they called “an urgent and resolute demand” that the organization “immediately adopt rules” to ban trans-identifying teens from participating in high school athletics in Colorado. Signed by 80 signatories representing 14 public school districts, ten charter schools, and one BOCES (Board of Cooperative Educational Services), the letter references President Trump’s February 5 Executive Order, “Keeping Men out of Women’s Sports,” and suggests that CHSAA will be subject to federal investigation if it does not comply with the letter’s demands.
