LAFAYETTE, LA - In the first court hearing ever about sex segregation in coed public schools, the American Civil Liberties Union and the ACLU of Louisiana argued today that the school board in Vermilion Parish, Louisiana illegally discriminated against both boys and girls at Rene A. Rost Middle School by segregating all grades in all core curriculum classes by sex. The lawsuit was filed on behalf of two girls who were placed in single-sex classrooms at Rene A. Rost, the only middle school in the city of Kaplan, Louisiana. The hearing is expected to last through Friday.
