Summary:
The city of Greenwich, Connecticut, is served by 9 public schools in the Greenwich School District—6 elementary schools, 2 middle schools, and 1 high school—enrolling 5,647 students total. The district ranks 14th out of 153 Connecticut districts (91st percentile, 5 stars), and every school in Greenwich exceeds state test averages by wide margins. However, the district is far from uniform: North Street School ranks 8th in the state, while Hamilton Avenue School ranks 161st among elementary schools.
Among the elementary schools, North Street School and Parkway School are the top performers, with 4th-grade ELA proficiency near 95% and very low poverty rates. The most dramatic story is New Lebanon School, which climbed from the 63rd percentile in 2023-24 to the 98th percentile in 2025-26 despite having the district's highest poverty rate (61.6% free/reduced lunch) and the highest per-student spending ($44,272). Hamilton Avenue School faces the biggest challenges, with math proficiency roughly 25 points below the district average and chronic absenteeism at 17.5%—above the state average. Julian Curtiss School also has high absenteeism (17.0%) and below-district scores, while Glenville School saw its ranking drop from 47th to 119th in one year.
At the secondary level, Greenwich High School is a standout with a 98% graduation rate and science proficiency nearly 38 points above the state average. Central Middle School outperforms Western Middle School in nearly every subject, but both lag the district average in middle school math. Spending does not always predict results: Parkway School and North Street School spend moderately yet achieve top rankings, while Glenville School spends the least. Overall, Greenwich is an elite district, but families should look closely at individual schools, as poverty, attendance, and test scores vary widely across the same town.
