Summary

Old Greenwich School is a PK–5 elementary school serving 385 students in the affluent coastal community of Old Greenwich, CT, within the Greenwich School District. It ranks 12th out of 491 elementary schools statewide (98th percentile) and has never dropped below the 91st percentile over the past decade. With a low student-teacher ratio of 10.5:1 and per-pupil spending of $33,050—the highest among comparable schools—Old Greenwich enjoys exceptional resources that drive strong academic results.

Academically, Old Greenwich far exceeds state averages. In 2025-2026, 3rd grade math proficiency was 92.5% versus 52.2% statewide, and 3rd grade ELA was 86.6% versus 47.3% statewide; 5th grade science reached 84.5%, compared with 52.9% statewide. The one soft spot is a recent 5th-grade dip: this cohort scored 89.3% proficient in both ELA and math as 4th graders in 2024-2025, but fell to 79.3% in ELA and 74.1% in math in 2025-2026, slightly below district averages. While Old Greenwich ranks an impressive 12th in the state, its immediate Greenwich neighbors North Mianus School and Riverside School have taken the top two spots statewide, making this an unusually strong cluster. Subgroup performance is also strong: White students ranked 7th and female students ranked 15th statewide in 2025-2026.

Old Greenwich serves a highly affluent population, with only 2.34% of students qualifying for free/reduced lunch—among the lowest in the area. By contrast, schools in the neighboring Stamford School District just 2–3 miles away, such as Stillmeadow School, Hart School, and Westover School, report poverty rates above 54%. Chronic absenteeism is a modest concern: at 9.6% in 2025-2026, it is below the state rate of 16.4% but above the district average of 8.5% and higher than peers like Riverside School (4.6%) and North Mianus School (4.9%). The bottom line: Old Greenwich is an elite, high-resource school with a long track record of excellence. The 5th-grade dip and rising absenteeism are trends worth monitoring, but the school is well-positioned to return to the top 5.
