The NAIA’s Council of Presidents approved the policy in a 20-0 vote. The NAIA, which oversees some 83,000 athletes at schools across the country, is believed to be the first college sports organization to take such a step.

According to the transgender participation policy, all athletes may participate in NAIA-sponsored male sports but only athletes whose biological sex assigned at birth is female and have not begun hormone therapy will be allowed participate in women’s sports.

A student who has begun hormone therapy may participate in activities such as workouts, practices and team activities, but not in interscholastic competition.
