A group of girl’s schools in the UK has declared they will not allow biological males to enrol, regardless of how they identify. They stated they are concerned about “jeopardizing single-sex status” and will be seeking “guidance from the government”.

Last month, the Girl’s Day School Trust (GDST), which represents 25 institutions, updated the new policy and notified its members, parents, and trustees.

The GDST stated in a new admissions section that its schools do not accept applications from students who are legally biologically male, even if they identify as female.

They claimed that a policy based on “gender identity” rather than the sex on a student’s birth certificate would jeopardize GDST schools’ status as single-sex schools under the 2010 Equality Act.

Female students who identify as male will be permitted to stay if they begin transitioning while enrolled.

The guidance was created “in collaboration with experts, teachers, and students,” according to the GDST, which includes Greater London’s 137-year-old Sutton High School among its members.

Binary spokeswoman, Kirralie Smith, said sex-based realities must be protected.

“Single-sex schools should retain the right to exclude the opposite sex from enrolment,” she said.

“Biological sex matters. The reality of sex is not changed by a person’s feelings or their ideological agenda.”
