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 love the massive amount of variety that the classes have to offer, as well as the academic support that a lot of our teachers give. While there are diversity and football team problems, other sports and the arts programs do very well state-wide. The band is an especially large and historic part of school culture.

Pros: Most of the teachers (especially the English teachers) are very helpful and classes are well taught, the staff as well. The school cares about what most students have to say (imo) and provide opportunities for anyone who needs it. Cons: Math teachers (Alg2/Precalc) are bad at teaching, lots of kids I know who never had issues with learning math have dropped classes and take them outside of school. not diverse at all; 70% white, 29% Asian, and 1% other. Kids are racist. The academic pressure is high depending on who your kid hangs out with. Fair warning, lots of 14 year olds are already drinking and using drugs regularly. in the bathrooms its common to see substance abuse (vaping), it's not that surprising anymore

Academically, super good. However the school culture is incredibly toxic and everyone is under way too much stress to be better than each other

I am saying this from my experience as a former student who actually pushed my family to move back to where we originally came from and after living there for exactly three years, we left because it was HORRIBLE. I know a lot of...

The math and science department have long been problematic. Post pandemic, the district spent hundreds of thousands of dollars on a new math curriculum, without providing the appropriate professional development and training for teachers to properly implement the curriculum that is supposedly more i...
