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.

The school is only for gifted talented kids, take tests for admissions and there is lot of biased atmosphere.

Stargate is a tremendous school. Our youngest son is special needs and the staff and faculty didn't bat an eye, they focused on what we needed in order for our son to be able to attend Stargate, which was not the same experience we had at another school we visited. The academics and students are tremendous. Just an exceptional school.

Small school where people really care. Some teachers aren't the best but the majority are great. Building is clean and is pretty safe. Could be more accessible, doors inside and out, ramps, and more.

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...
