Summary:
Seymour School District is served by a single middle school, Seymour Middle School, which educates roughly 494 students in grades 6 through 8 at 211 Mountain Rd. in Seymour, CT, making the school a focal point for the district's middle-level education with no internal school-to-school comparisons available.
As the only middle school in the district, Seymour Middle School stands out most for its exceptional upper-grade STEM performance. In the 2025-2026 school year, 8th graders achieved 69.3% proficiency in Science, outpacing the Connecticut state average by a striking 18.4 percentage points, while 8th grade Math proficiency reached 53.7%, an 11.8-point advantage over the state. The school also shows a compelling upward trajectory in math relative to the state as students advance, moving from below average in 6th grade (-3.1 points), to above average in 7th grade (+4.4 points), to well above average in 8th grade (+11.8 points). Despite being the district's top-rated school, it earned a 3-star rating and ranked in the 57th percentile of Connecticut middle schools, a stronger showing than the overall Seymour School District, which earned only 2 stars and a 36th percentile district ranking.
While its math and science results in the upper grades are encouraging, English language arts remains an area for improvement, with proficiency rates roughly 3 points below the state average across all grades. Attendance also merits attention: the school's chronic absenteeism rate of 15.0% is below the state's 16.4% but notably higher than the district's 12.8% average. Financially, the school spends $15,875 per pupil and maintains a favorable student-teacher ratio of 13.1. The most optimistic data point is the dramatic improvement in 8th grade science proficiency from 52.3% to 69.3% year-over-year, suggesting a targeted area of instructional strength worth celebrating for families considering this school.
