A Louisiana charter school is banning pregnant students and requiring "suspect" girls to take a pregnancy test. Now the ACLU of Louisiana is threatening legal action unless the policies are changed at the state-funded Delhi Charter School by late next week. "The policy discriminates against female students not just for being pregnant but even for the possibility that they might be pregnant, and treats them as though pregnancy was some kind of contagious disease," the executive director of the ACLU of Louisiana told TODAY.com. "That is a gross violation of the law." There was no response from the school, but officials from the State Department of Education said they are now requiring "an immediate change to the policy."
