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 (search) 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.

Stob could not be reached for comment.

School administrators learned of the parents' relationship this week after Shay and another cheerleader were reprimanded for talking to the crowd during a Sept. 16 football game, according to Clark and her partner, Mitzi Gray.

After school officials told Clark that her daughter could no longer attend the school, the mother was ordered to remove Shay from cheerleading practice, collect the girl's belongings and leave the property.

The district refunded Clark and Gray $3,415 — Shay's tuition for half the year plus an art fee.

Clark and Gray, who have been together 22 years, have two other daughters aged 9 and 19.

Two weeks ago, a lesbian student filed a lawsuit against the Garden Grove Unified School District (search), alleging that officials suspended her several times and forced her to temporarily transfer to another campus because she refused their orders to stop hugging and kissing her girlfriend on school grounds.
