School Reviews
2 10/10/2025
MAP scores dropping with each passing year. Math teachers and Math scores will not impress anyone. A lot of bullying, drugs, bad behavior in general, and I'm not seeing where the faculty is doing anything about it. At one time I had a very very high opinion of this school, but it has changed and not for the better. I will give them this though; those who do participate in the extracurricular activities, teachers as well as students, seem to participate with a great deal of pride and hard work.
