Summary:
Zip code 06070 is served by four top-performing public schools in the Simsbury School District, spanning elementary through high school (PK–12) and enrolling nearly 3,000 students. All four schools rank in the 90th percentile or higher statewide, with every school holding a 5-star rating and beating Connecticut state averages in nearly every subject and grade level.
Simsbury High School is the district’s flagship, ranked 6th among Connecticut high schools with a 97.7% graduation rate and exceptional SAT/NGSS scores – though its math proficiency (58.3%) lags well behind its ELA (86.1%) and science (88.5%). Among elementary schools, Squadron Line School is the largest (710 students) and has the district’s lowest chronic absenteeism at 4.7%, while Central School is the smallest (393 students) but posts the highest elementary math proficiency (78.8%), including an 86.5% 3rd-grade math rate. Henry James Memorial School is the middle school (grades 7–8) and has improved its state ranking three years in a row (31st → 24th → 21st), with strong 8th-grade science (76.2%) but the highest chronic absenteeism in the district at 11.4% – even higher than the high school’s 9.7%.
Notable patterns include a clear spending divide: secondary schools spend roughly $18,300 per student versus about $15,500 at the elementary level. Math is the consistent relative weakness across all schools, but the gap is most dramatic at the high school (27.8 points behind ELA). Despite varying free/reduced lunch rates (11–18%), all schools perform at elite levels, suggesting strong district-wide support systems. While Squadron Line slipped slightly in its ranking (from 24th to 38th), and Central pulled back from a breakout year (23rd to 34th), both remain in the top 10% of elementary schools. The main areas to watch are middle-school absenteeism and high-school math, but overall this is an unusually consistent, high-achieving district where families can expect excellent outcomes at every grade level.
