This school is a great school when it comes to a community setting. Student's are proud to be a Hawk. The academics aren't horrible either. The school offers an intervention period every Wednesday where the student's can come in to class, retake their quiz or ask questions about an assignment. There ...  Read more

I graduated in 2000 from horizon high. At the time I wasn't crazy about it, because I moved from a small school in the mountains (Platte Canyon High) and horizon was a bit of a culture shock. In hindsight, it was one of the best experiences of my life, and one that I will cherish. I went here for my ...  Read more

Worst school ever! Administration and teachers are bad and the football program is the worst! I've never seen anything like it.. Everything is brain surgery and I highly recommend choicing your child into a different school!

I attended this school for 3 years and it was horrible. The deans where rude and acted more like police (garcia) rather than deans. Needles to say I moved high schools and graduated elsewhere. Do not sign up here it is horrible

I would have to say this school could be better if the teachers were better. Don't get me wrong I have had some of the most amazing teachers there are but I've also have had some of the worst teachers like last year my math teacher was wonderful but I think she is the only good math teacher there. I'm ...  Read more

School without a community of students and staff is just an empty building. If we want the school to improve, we as students and the staff need to improve. A student can walk inside a classroom with an already negative preconception of the teacher and class, or walk in with an open mind. Not all of ...  Read more
