The best part about going to Horizon was probably the clubs because they were all inclusive of everyone no matter what. They brought good to the community. The worst things about Horizon was the inconsistency with the sports that we had. From coaching to players.
8/11/2025
Large school with a diverse student base. Lots of resources and generally good teachers. Art teacher was bad. Routinely removed students (transferred to an alternative school) if they were deemed unlikely to graduate.
7/11/2025
I loved my time at Horizon. I did things that made me uncomfortable but those experiences helped me to grow and have an amazing time. Teachers and other admin knew me by name even though I had never been in their office before.

My student had access to a high quality, well rounded education with support by many caring individuals at this school. I recommend it.
10/15/2018
I would rate the school a 0 out of anything. My experiences throughout my three and a half (I graduated a semester early because I hate the school.) year were horrible, I've had only 7 teachers that cared for the students (I've gone through a total of around 30 teachers). At the end of my junior yea...

The Special Education program at this school is terrible because of the special ed gives a shit about kids and actually helping them out when they need it all they do is sit there saying they care when they could care less if your kid is helped. And of course the school does shit about stopping bull...

A family member of mine got violentlt attacked here during an off hour and kids took videos. The school is backing the bully. If you love your child-do not send them here. This school is disgraceful.
