Best Public Schools in Zip Code 06241

The three public schools serving ZIP code 06241 in Dayville, CT — Killingly Central School, Killingly Intermediate School, and Killingly High School — are all part of the Killingly School District and together enroll about 1,753 students across grades PK–12. The district ranks 118th out of 153 Connecticut districts, placing it in the 23rd percentile with a 1-star rating. Economic need is significant at every school, with free/reduced-price lunch eligibility ranging from 42.88% at the high school to 52.31% at the intermediate school and 60.25% at Central. Because Killingly Central serves only PK–1, it has no standardized test scores or recent state ranking.

Killingly High School is the standout in the ZIP code: ranked 70th of 141 high schools (50th percentile, 3 stars), it improved sharply from 95th the prior year and is the only school here above the state average in any core subject, with 62.6% SAT ELA proficiency versus 58.0% statewide. Math is a glaring weakness at just 16.6% proficiency. Killingly Intermediate School sits near the 40th percentile in ranking and has consistently low math scores across grades 5–8, though its 8th-grade science proficiency reached 52.1%, slightly above the state’s 50.9%. Killingly Central School, despite having the highest poverty rate, posts the best attendance: 17.1% chronic absenteeism versus 23.0% districtwide and 16.4% statewide.

The most striking pattern is how chronic absenteeism escalates with grade level: 17.1% at Central, 24.3% at Intermediate, and 29.1% at the high school — nearly double the state rate. The high school’s graduation rate is 86.9%, below the state’s 91.2%. Math underperformance is a systemic crisis across all three schools, and higher per-pupil spending at the high school ($17,419) has not translated into stronger math or science results. For parents, the picture is mixed: strong ELA and science bright spots exist, but improving math achievement and attendance in grades 5–12 are the clearest priorities for this community.
