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.

Stargate is a gifted and talented school. The academic at this school is phenomenal, offering many AP classes, honors classes, and traditional classes. They will pay for you if you choose, during your high school career, to take a college class at a community college. Their mental health advocation is very good. Unfortunately, some of the kids are unmotivated and skip class a lot.

It is a very academically strong school, but can be somewhat demanding. It does a good job at college prep and is a good school overall.

At school participating in extraculicular activities was one of my favorite things. Reaxhers involved us in arts such as painting and poetry and these were the things i loved the most. It was the best thing knowing that I am a student of the school. It was such a great pleasure.

Half of Stargate teachers can't teach right. In recent years Stargate failed to hire good teachers, they are filling the teacher positions with subs and paras. If a teacher do not accept offer at the beginning of the school year or if they leave in the middle of the school year, then that class runs...

As other reviewers have mentioned, Stargate has a bullying problem. They claim to have a 'no tolerance' policy, but there is no follow through with discipline. The safety at this school to deter a shooter is seriously lacking. The grading system--80% of a student's grade is test scores; only 20% fro...
