At the School I went to we were also taught the different religions. We even have non catholic kids going to school there. The skirts are at the knees right now. But girls are also allowed to wear slacks. That started a couple years before I got into HS. Grade school when I went wore normal clothes till we got into HS then uniforms were required. I never regretted going to a Catholic school. Even though I dont believe in everything they teach. I was glad for the opportunity to pray and have people that believed the same around me.
