GreatSchools Rating
The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.

My experience at Horizon has been an okay experience. That being said, my friends and peers were very good overall in terms of respect and making an atmosphere. I would like to see an improvement with the football team/coaches. Adding to improvements, I would like more promotion of the DECA program as I see it as a very valuable experience. Staff and admin were all good people and made a good atmosphere for students to be in. Overall, the experience was quite good.

Horizon High School has helped me an incredible amount, to find out what I want to do with my life. My overall experience has been great, with no problems with any of the staff, and a very large amount of opportunity to grow socially, academically, and ethically.

My experience at Horizon High School was mixed. In the beginning, it was great, I made lots of friends, did well in classes, got close with some staff, and loved being in high school at first. As I went through the years, I met some teachers I didn't get along with, some relationships fell apart, and classes got harder for me to get through. High School did get stressful, the people in the school got annoying and rude, but overall I am just here to get my Diploma.

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.
