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.
12/14/2024
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.

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...

Not impressed at the elementary level. Maybe high school is better but the elementary school feels blah and I really don't see how it is different/better than a regular neighborhood school other than the highly over rated 'SEL' curriculum, the usefulness of which at this stage of a kid's life is dub...
