Summary

Deep River Elementary School, in the town of Deep River, CT, serves 189 students in grades PK-6 and currently holds a 4-star rating, ranking 113th out of 491 Connecticut elementary schools (77th percentile) for 2025-26. The school is part of the Deep River School District, which itself rates 3 stars and ranks 50th out of 153 districts statewide. Academically, Deep River is a consistent standout: in the most recent testing year, its students outperformed Connecticut state averages in English language arts, mathematics, and science in every tested grade and subject combination except 4th-grade ELA. Science and upper-elementary math are particular strengths — 5th-grade science proficiency was 77.8% versus 52.9% statewide, and 5th-grade math reached 70.4% versus 45.8% statewide.

These results hold up well against nearby schools. Deep River's 5th-grade math (70.4%) and science proficiency (77.8%) exceed Haddam-Killingworth Intermediate School (54.7% and 68.8%), and its 3rd-grade ELA (69%) and math (72.4%) beat Killingworth Elementary School (63% and 57.4%) and East Haddam Elementary School (62% and 59.5%). Its closest geographic peer, Chester Elementary School, just 1.68 miles away, trades strengths: Deep River edges Chester in 3rd-grade math (72.4% vs. 70.6%), while Chester holds a substantial 5th-grade math advantage (83.3% vs. 70.4%). The one visible weak spot is 4th-grade ELA, at 56.3% — only slightly above the state average and trailing Daisy Ingraham School (71.8%) and Kathleen E. Goodwin School (70.9%). Notably, Deep River achieves these results while serving a higher share of economically disadvantaged students (32.3% free/reduced lunch) than many neighboring schools.

Attendance is a clear differentiator: Deep River's chronic absenteeism rate is just 7.6%, less than half the state average of 16.4%, and consistently far below state levels in recent years. The school also maintains a favorable student-teacher ratio of 9.8, lower than nearby Haddam-Killingworth Intermediate School (12.7), Lyme Consolidated School (12.6), and East Haddam Elementary School (12.1). While the school's statewide ranking has cooled from its 2021-22 peak of 46th (5 stars), it remains comfortably in the top quarter of Connecticut elementary schools with a decade-long track record of strong performance.
