Summary:
The city of Groton, Connecticut, is served by one middle school: Groton Middle School, which enrolls 884 students in grades 6 through 8 and is part of the Groton School District. The school serves a predominantly economically disadvantaged population, with 80.77% of students eligible for free or reduced-price lunch, yet it maintains a supportive 11.7:1 student-to-teacher ratio.
Groton Middle School has shown meaningful improvement. Its state ranking climbed from 144th out of 252 middle schools (43rd percentile, 2 stars) in 2024-2025 to 129th out of 258 (50th percentile, 3 stars) in 2025-2026. The school improved in every single tested subject year over year, with particularly strong gains in 8th grade ELA (+9.7 points) and 8th grade science (+6.8 points). Seventh grade represents the school's strongest cohort, exceeding the state average in ELA (53.4% vs. 52.2%) and essentially matching it in math (44.0% vs. 44.1%). Chronic absenteeism is just 14.3%, lower than both the district (16.5%) and state (16.4%) rates, a positive sign given the school's high poverty level.
The most persistent challenge is 8th grade math, where proficiency improved to 31.7% but still trails the state average of 41.9% by more than 10 points. Eighth grade science also improved substantially to 45.0% yet remains nearly 6 points below the state average of 50.9%. Despite these gaps, Groton Middle School consistently outperforms its district averages across nearly every subject and grade, positioning it as a bright spot within a district ranked 105th out of 153 in Connecticut. With strong attendance and broad-based academic gains, the school appears well positioned to continue its upward trajectory.
