High Schools in Manchester School District

Manchester School District in Manchester, Connecticut, is served by a single high school, Manchester High School, which enrolls 1,703 students in grades 9–12. As the only high school in the district, it is the standout by default, and its performance tells a story of a school that leads its district but trails the state. The school beats the Manchester School District average on every reported academic metric, including ELA proficiency (46.2% vs. 44.7%), math proficiency (21.3% vs. 20.2%), science proficiency (30.2% vs. 28.2%), graduation rate (88.3% vs. 87.9%), and chronic absenteeism (19.7% vs. 21.3%, meaning better attendance). However, compared to Connecticut statewide averages, Manchester High School is below in all categories, particularly in science (30.2% vs. 50.5%) and math (21.3% vs. 31.3%). Its state ranking has improved slightly, moving from the 33rd percentile in 2023–2024 to the 36th percentile in 2025–2026, with a 2-star rating.

Key statistics show a school with clear challenges and some bright spots. The graduation rate is a solid 88.3%, though nearly 3 points below the state rate of 91.2%. Chronic absenteeism affects 19.7% of students—about 1 in 5—which is better than the district average but worse than the state’s 16.4%. Math proficiency is particularly low, with only about one in five students proficient, though it did improve by 3.0 points year over year, the largest gain among subjects. Science proficiency represents the widest gap with the state, a 20.3 percentage point shortfall. The school serves a majority low-income population, with 58.54% of students eligible for free or reduced-price lunch, a factor that often correlates with academic outcomes.

Per-student spending is substantial at $19,821 (from 2018–2019), and the student-teacher ratio is a low 11.1, indicating meaningful investment in the school. Manchester High School is the strongest academic performer in its district, but it remains below statewide benchmarks. The most pressing needs are improving science and math achievement, while addressing chronic absenteeism. Encouragingly, the school’s ranking has ticked upward over the last two years, and its performance relative to the district suggests that targeted support could close the gap with Connecticut as a whole.
