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.

I really love the school, academics, and teachers. All of the staff is really amazing and so kind, understanding, and supportive. You can take as many advanced classes as you want and feel comfortable with, and you are given all the materials you need to succeed. There are so many really nice people, but there's also some really cruel people though.

The best part about Mt. Si is there is lots of ways to get student involvement, including clubs and sports. It also has a beautiful campus. Personally, the worst part about Mt. Si is that many schools come together making the school a far commute for me.

I transferred into this school mid-semester, working hard to catch up and adapt to my new school. My new school counselor set me up with a 504 plan to accommodate my neurodiversity, and after 11 years of school was finally able to block out the noise and really focus. I found a new passion for math, a subject I had previously struggled with.

Students with IQs high enough for MENSA are not considered gifted...

Both my kids attended Mount Si. They both participated in sports, took several AP courses and both graduated with honors. Most of their teachers were great and the kids were able to work to their own level of ability. They were both prepared for college (one graduated, one still in) and I'm so glad...

This school has does not care about their drama program it is disappointing to a lot of students. They just got a new stage this year and won't let the drama students perform anything on it. They are horrible with communication and their Covid safety plan was half baked. Sport and activities teacher...
