Best Elementary Schools in Zip Code 06095

There are 4 elementary schools in zip code 06095 (Windsor, CT), all part of the Windsor School District, which is ranked 123 out of 153 Connecticut districts. Two schools serve PK–2 (Oliver Ellsworth School and Poquonock Elementary School) and two serve grades 3–5 (John F. Kennedy School and Clover Street School).

For parents comparing the two schools with test data, John F. Kennedy School is the stronger academic performer, earning a 2025–2026 state rank of 331 out of 491, slightly ahead of Clover Street School at 343. JFK posts the best 5th grade ELA (49.6% proficient) and 5th grade math (29.9%), and is the only tested school with reported 5th grade science data (47.5%). However, Clover Street School clearly excels in 3rd grade, where its ELA (49.1%) and math (48.6%) scores are well above JFK’s. When it comes to attendance, Poquonock Elementary School stands out with a chronic absenteeism rate of just 5.2% — far better than the district average of 14.3% and the state average of 16.4%. Clover Street School spends the most per student ($22,378) and has the lowest student-teacher ratio (9.7:1), yet these resources do not translate into the highest scores.

Across the board, academic proficiency trails Connecticut state averages in nearly every subject and grade — the lone exception is Clover Street’s 3rd grade ELA. The most troubling area is 5th grade math, with JFK at 29.9% and Clover at 23.3% versus the state’s 45.8%. Year-over-year changes are also inconsistent, with JFK improving in 5th grade but dropping sharply in 4th grade ELA (−9.1), while Clover surged in 3rd grade but fell steeply in 5th grade. The two PK–2 schools (Oliver Ellsworth and Poquonock) have no current test data since SBAC testing begins in 3rd grade, but their strong attendance suggests positive early-learning environments, even as their academic performance remains a “black box” for parents.
