Best Public Schools in Zip Code 06417

The 06417 zip code, covering Deep River, Connecticut, is served by three public schools—Deep River Elementary School (PK–6, 189 students), John Winthrop Middle School (7–8, 197 students), and Valley Regional High School (9–12, 429 students)—operated by Deep River School District and Regional School District 04, with a combined enrollment of 815.

Deep River Elementary School is the clear standout: it ranks 113th out of 491 Connecticut elementary schools (77th percentile, 4 stars) and beats state proficiency rates by 5 to 25 points in every subject and grade, including 74.1% in 6th grade ELA versus 51.2% statewide. It also has the highest free/reduced lunch rate in the zip code (32.28%), yet still posts the strongest academic results. Chronic absenteeism is just 7.6%, far below the state’s 16.4%. Valley Regional High School stands out for its 97.4% graduation rate and stable 45th-place ranking among 133 high schools (66th percentile, 3 stars), improved from 64th in 2023–2024. Its ELA and science proficiency are well above state averages (68.0% vs. 55.3%, and 63.5% vs. 50.5%), but math proficiency is essentially flat at 31.1% vs. 31.3% statewide. John Winthrop Middle School is the concern: it dropped from 61st to 99th place (76th to 62nd percentile) between 2024–2025 and 2025–2026, with 7th grade ELA falling 9.1 points and 7th grade math falling 10.2 points, though it still hovers near or above state averages and keeps absenteeism low at 9.0%.

Attendance is a community-wide strength, with all three schools below the state’s 16.4% chronic absenteeism rate. However, per-student spending figures are unreliable: Valley Regional shows $3,132 per student, John Winthrop $53,789, and Deep River Elementary $22,748—a 17-fold gap that almost certainly reflects inconsistent accounting, not true cost differences. Enrollment patterns also reveal regional consolidation: the middle school serves only 7th–8th grades but enrolls 197 students, nearly matching the PK–6 elementary school’s 189, indicating students come from neighboring towns through Regional School District 04. Overall, 06417 is a small, above-average school cluster with high graduation rates, low absenteeism, strong elementary performance, and two areas to watch: the middle school’s sharp decline and the high school’s math proficiency ceiling.
