Summary:
The Wilton School District, a highly ranked Connecticut district (11th of 153, 93rd percentile, 5-star) in an affluent suburban area, serves 1,676 elementary students across two schools: Miller-Driscoll School (grades PK–2) and Cider Mill School (grades 3–5).
Because the district splits elementary grades between the two buildings, Cider Mill School is the only one with state test data and stands out as the academic powerhouse: it ranked 68th of 491 Connecticut elementary schools in 2025–2026 (86th percentile) and reached 46th in 2024–2025. Its SBAC and NGSS proficiency rates run 20 to 30 percentage points above state averages in every subject. Miller-Driscoll School, while lacking test data, anchors the system with a strong early-education environment: a 13:1 student–teacher ratio, $20,789 per-student spending, a 2.72% free/reduced lunch rate, and just 4.5% chronic absenteeism. The two schools function as one cohesive elementary pipeline rather than direct competitors.
Both schools serve very low-poverty populations, with Cider Mill's free/reduced lunch rate (5.05%) nearly double Miller-Driscoll's, though both are far below state norms. Chronic absenteeism is exceptionally low district-wide at 3.9% versus 16.4% statewide. Notable year-over-year shifts at Cider Mill include a decline in 5th grade ELA proficiency from 88.1% to 79.3% and a strong gain in 4th grade math from 78.0% to 83.3%. With roughly $20,800–$20,900 spent per student and small 12–13:1 classes, Wilton delivers a top-tier, well-resourced elementary experience.
