Summary

Thompson Middle School serves 262 students in grades 5–8 in North Grosvenordale, CT, and is part of the Thompson School District. The school's biggest strength is attendance: chronic absenteeism is just 11.4%, well below the state average of 16.4% and far better than nearby Killingly Intermediate School (24.3%) or Putnam Middle School (18.9%). About 46% of students qualify for free/reduced lunch, and the student-teacher ratio of 10.0 is the lowest among neighboring middle schools.

The academic picture is more challenging. Math proficiency ranges from 25% to 30% across grades 5–8, roughly 15–20 percentage points below state averages. That places Thompson in the lower tier alongside Putnam and Killingly, while Woodstock Middle School and Brooklyn Middle School post math scores around 55%. ELA results are more volatile: 8th graders exceeded the state average in 2024–2025, but 5th and 7th grade scores slipped the following year. Science is a relative bright spot, with 5th grade proficiency at 51.3%, close to the state's 52.9%.

One striking finding is the gap between resources and results. Thompson spends $17,634 per student and has the smallest class sizes among nearby schools, yet its test scores trail schools like Woodstock Middle School that spend less and have larger classes. On a positive note, the school's low-income students perform near the statewide median, which suggests effective support for that group. With attendance now stable, Thompson's next challenge is turning that strong foundation into meaningful academic growth.
