Middle Schools in Killingly School District

Killingly School District is served by a single middle school, Killingly Intermediate School, which enrolls 692 students in grades 5 through 8 and serves a community where 52.31% of students qualify for free or reduced-price lunch. The school has held a steady statewide position over the last three years, ranking 154th out of 258 Connecticut middle schools (40th percentile) with a 2-star rating in 2025–2026, essentially unchanged from the prior two years. While the school outperforms its district — which ranks in the 23rd percentile statewide — both remain below the Connecticut midpoint.

Academically, the school's biggest weakness is math. Only 26.4% of students scored proficient in SBAC mathematics, compared with a 44.1% state average, with every grade level falling well below state proficiency; 5th grade shows the largest gap at 21.9% versus 45.8% statewide. English Language Arts shows a narrower gap, with 43.9% proficient versus the state's 52.0%, though 7th grade notably dropped from 53.4% proficiency in 2024–2025 to 34.9% in 2025–2026. The standout subject is 8th-grade science, where 52.1% of students scored proficient — above the state average of 50.9% and a significant 14.5-point gain over the previous year.

Chronic absenteeism is a serious concern, with 24.3% of students chronically absent — about 1.5 times the state rate of 16.4% — and this likely contributes to the academic gaps. The school's student-teacher ratio of 12.3 is favorable, and per-student spending of $16,611 is above average, providing resources for targeted support. Year-to-year scores show considerable volatility across grade cohorts, including a 15.4-point gain in 6th-grade math, a 16.8-point gain in 8th-grade math, and an 18.5-point drop in 7th-grade ELA, suggesting results vary significantly with each cohort. For parents, the key takeaways are strong 8th-grade science performance, a stable overall ranking, and a school that faces meaningful challenges in math proficiency and attendance that will require continued attention.
