High Schools in Cromwell School District

Cromwell High School is the only high school in the Cromwell School District, serving grades 9–12 with 515 students in a mid-sized, single-high-school district. Despite the district’s overall middle-of-the-pack ranking (72nd out of 153 Connecticut districts), the high school is a clear standout: it currently ranks 27th out of 133 high schools statewide, placing it in the top 20% and earning a 4-star rating. The school also posts a 97.0% graduation rate, well above the state average of 91.2%, and a favorable 11:1 student-teacher ratio that supports personalized attention.

Academically, Cromwell High School outperforms Connecticut state averages across all three tested subjects for 2025-2026. English Language Arts proficiency is especially strong at 76.8% (state: 55.3%), while science sits at 68.3% (state: 50.5%) and math at 47.8% (state: 31.3%). The most striking trend is in science, which jumped from 45.0% proficient in 2024-2025 to 68.3% in 2025-2026—a 23.3-point swing that turned a relative weakness into a major strength. Math remains the school’s weakest subject, with a 29-point gap between ELA and math proficiency, though it still stays comfortably above the state average. Chronic absenteeism at 14.4% is better than the state’s 16.4% but higher than the district’s 12.2%, suggesting high school attendance is a bigger challenge than in lower grades.

With about 29.9% of students eligible for free or reduced lunch, the school serves a moderately economically diverse population while still achieving high results. Its statewide rank has fluctuated in recent years—#41 (2023-2024), #54 (2024-2025), and #27 (2025-2026)—likely due to its small size and cohort-to-cohort variations. Overall, Cromwell High School is a strong, supportive school that consistently beats state averages on key measures. Its high graduation rate, excellent ELA scores, and rising science performance make it a standout option in central Connecticut, though families should be aware that math proficiency remains the area most in need of improvement.
