Best School Districts in Connecticut (2026)
This ranking covers 155 rated public school districts in Connecticut, scored using NCES EDFacts state assessment data (2021–22 for 90% of districts, 2017–18 fallback for the rest). Each district's reading and math proficiency rates are averaged, then ranked against other districts in the same state to produce a 1–10 score.
A district's score reflects how its students perform on state assessments relative to same-state peers — it is not a direct measure of teaching quality, school culture, or individual student outcomes. Always visit schools, talk to local families, and contact districts directly before making decisions. Learn how ratings are calculated →
