Summary:
The Colchester School District serves two elementary schools — Colchester Elementary School (grades PK–2, 552 students) and Jack Jackter Intermediate School (grades 3–5, 509 students) — in a district rated 3 stars and ranked 76th out of 153 Connecticut districts.
Jack Jackter Intermediate School is the district's academic standout, consistently exceeding Connecticut state averages in every subject and grade tested. In 2025–2026, ELA proficiency ranged from 51.2% to 57.6% versus state averages of 47.3% to 53.5%, while math proficiency ranged from 55.6% to 62.3% versus state averages of 45.8% to 52.2%. Mathematics is its strongest area, outperforming the state by roughly 9–10 percentage points in every grade. However, its state rank has declined from 179th in 2023–2024 to 224th in 2025–2026, suggesting other Connecticut schools are improving faster. Colchester Elementary School stands out for early-grade support, with a chronic absenteeism rate of just 9.1% — well below the district's 14.4% and the state's 16.4% — and a favorable student-teacher ratio of 11.7 compared to Jack Jackter's 13.0.
Both schools serve nearly identical demographics, with free/reduced lunch rates of 27.17% and 27.31%, making comparisons between them especially meaningful. Chronic absenteeism is a clear district strength: Colchester Elementary sits 7.3 percentage points below the state rate, and Jack Jackter is 5.4 points below. Spending and staffing reveal an interesting trade-off: Jack Jackter spends slightly more per student ($17,169 vs. $16,895) yet carries a higher student-teacher ratio (13.0 vs. 11.7). A data caution: spending figures date to 2018–2019, and because Colchester Elementary serves grades PK–2, it has no state test scores, so the district's full academic picture emerges through Jack Jackter's results and later outcomes.
