EVERYONE ignores me like I'm invisible when I've been here for eight months!!!! I haven't made a single damn friend because people are so selfish and cliquey here! My only friends are my teachers. A lot of snooty people here, I much rather prefer Hart High School. Good teachers and helpful staff but the students aren't cool.

needs nicer coaches, not enough visual art classes (photography, drawing, painting)

There are many teachers that are extremely helpful and always available to all students who need extra help,especially those student who are proactive. The Counselors are friendly, available and professional with students and parents. There are many excellent clubs to fit student鈥檚 needs. The football upper management needs an over hall, but the other sports have excellent staff and coaches. My only complaint is with office staff, like attendance, student store, and career center. They tend to be condescending and impatient. They may even make an unecessary negative remark or repremand, perhaps forgetting that there job is to answer questions without judgment.

An absolutely terrible school. I never saw an adult there who truly had a passion for their job and wanted to help their kids. I never felt safe in the school atmosphere, and I never felt like there was anyone there who truly cared about my well-being. I attempted suicide in 9th grade because of the amount of stress/bullying school brought into my life. My life will forever be changed, because of some of the faculty and teachers at TOHS. Thank you TOHS, for ruining my life.
