ONTARIO, Calif. — A Christian school expelled a 14-year-old student because her parents are lesbians, the school's superintendent said in a letter.

Shay Clark was expelled from Ontario Christian School on Thursday.

"Your family does not meet the policies of admission," Superintendent Leonard Stob wrote to Tina Clark, Shay's biological mother.

The school's policy states that at least one parent cannot engage in practices "immoral or inconsistent with a positive Christian life style such as cohabitating without marriage or in a homosexual relationship," Stob wrote.

Shay and her parents said they will not fight the ruling. Shay will attend public school next week.
