Summary:

The Greenwich School District in Connecticut is home to 15 schools, including 11 elementary schools, 3 middle schools, and 1 high school. This high-performing district is known for its standout schools, with several institutions ranking among the top in the state.

At the elementary level, North Mianus School and Riverside School are ranked among the top 5 in Connecticut, with North Mianus School taking the #1 spot. In middle school, Eastern Middle School is ranked #2 in the state, boasting consistently high test scores and a 5-star rating. At the high school level, Greenwich High School is a strong performer, ranked #12 in Connecticut with a 4- or 5-star rating in recent years.

The district as a whole excels academically, with many schools seeing over 80% of students proficient or better in English Language Arts and Math. However, there is significant variation in performance and demographics between the schools. While top-ranked institutions like North Mianus, Riverside, and Eastern Middle have very low free/reduced lunch rates, other schools like New Lebanon School and Hamilton Avenue School have rates over 50%. Addressing these disparities could help raise outcomes district-wide.
