10/10GreatSchools RatingParent Rating AverageI am a current sophomore at Syosset High School as of now along with my sister who is a freshman. Looking at statewide averages and percentiles came as a surprise to us seeing how low they really were. Although many people say the school is too competitive, we take it as motivation, just as most of my peers do. The after-school activities are a real pro when considering Syosset High School. Anything imaginable is likely available to try. Teachers are either really good or pretty poor. New classes such as wellness support that most reviews under this post are incorrect, where mental health and safety are HIGHLY promoted. For us athletes, we received new lights for the turf field, a new state-of-the-art gym, and vast fields for various sports. If you are considering moving to Syosset and reading this, I would recommend you ignore the other comments as they are likely not motivated to compete and become successful later in life. I have a nice balance and equilibrium between hanging out with friends, sports, homework, and other hobbies.Parent Review3y ago
