A Delhi Charter School policy that prevents pregnant female students from attending school and can force them to take a pregnancy test to continue attending school if administrators "suspect" pregnancy has drawn the attention of the American Civil Liberties Union.

The News-Star report the ACLU sent a letter Monday requesting the school revise its policy or the group will consider further legal action.

Delhi Charter School's policystates the school seeks to maintain an environment where students will learn and exhibit acceptable character traits that govern language, gesture, physical actions and written words.

"The school reserves the right to require any female student to take a pregnancy test to confirm whether or not the suspect student is in fact pregnant," the policy reads.

The policy also allows the school to refer the student to a physician of its choice. "If the test indicates that the student is pregnant, the student will not be permitted to attend classes on the campus of Delhi Charter School."
