Summary:
Groton School District is served by one middle school, Groton Middle School, which enrolls 884 students in grades 6 through 8 and operates in an area where 80.77% of students qualify for free/reduced lunch.
Groton Middle School is the sole middle school in the Groton School District, so there are no direct school-to-school comparisons within the district. The school is showing clear momentum: its statewide ranking improved from 138th (45th percentile, 2 stars) in 2023–2024 to 129th (50th percentile, 3 stars) in 2025–2026, moving from below the median to exactly the statewide middle-school median. Every tested grade and subject improved from 2024–2025 to 2025–2026, with the largest gains in 8th grade ELA (+9.7 points), 8th grade science (+6.8), and 6th grade math (+5.6). This broad-based progress is especially notable given the school’s high poverty rate.
In 2025–2026, 7th grade stands out as a relative strength: ELA proficiency (53.4%) exceeds the state average (52.2%), and math (44.0%) is essentially tied with the state (44.1%). The biggest challenge is 8th grade math, where only 31.7% of students are proficient, a 10.2-point gap versus the state average (41.9%). Science proficiency in 8th grade (45.0%) trails the state by 5.9 points. The school’s chronic absenteeism rate of 14.3% is better than both the district (16.5%) and state (16.4%), and its student-teacher ratio of 11.7 is favorable. While the Groton School District ranks in the 31st percentile statewide, Groton Middle School performs at the 50th percentile among all Connecticut middle schools — a sign that the school is outpacing its district’s overall position and building on a solid foundation.
