9/10GreatSchools RatingParent Rating AverageThis school is only good if you are a white, male, straight athlete. All others are not welcome. No AP courses or languages offered. Science is limited. IEP’s are largely ignored. Bullying is rampant with the Administration turning a blind eye. Some teachers are blatantly hostile to students. No extracurricular activities outside of sports.Parent Review1y ago - Hill City Middle School - 04
