They let rapists stay in school and sports but make victims sign NDRs unless they wanna be suspended. They have a long history of racism and allowing sexual abuse to continue under the wire. Close Quote

This school is horrible. I had gotten bullied to the point I had to leave that school. I told teacher and even the vice principal about the bullying that was going on and the vice principal had laughed and said it was funny what had happened to me. She was buddy buddy with the kids who had bullied me so she thought it would be fun to joke around with them about what they did to me instead of taking it seriously. I have current students messaging me asking about what school I transferred to because they can't take the bullying anymore. The teachers act as friends to the students. I see teachers taking pictures in class with students and having their arm around kids as if they are a kid as well. This is a bad place and am very glad I got out of that place. I know numerous people who have left this school. 13 in one year. Because of bullying. Do not let you're kid go here. Close Quote

It was a super competetive school when I attended from 2000-2004. I scored a 29 on my ACT, and didnt realize that it was a good score until after I graduated. Close Quote
