Best High Schools in Clinton, CT

Clinton, Connecticut is served by a single public high school, The Morgan School, which enrolls 473 students in grades 9 through 12 and is part of the Clinton School District. As the only high school in this shoreline town, The Morgan School sets the academic tone for the community, and its performance relative to the district and state offers a clear picture of the educational experience families can expect.

The Morgan School stands out for its strong graduation rate of 97.5%, well above the state average of 91.2% and slightly ahead of its district's 96.7%. In recent assessments, the school consistently outperformed Connecticut in English Language Arts and Science; in 2024-2025, science proficiency hit 59.7% versus 47.7% statewide, a noteworthy 12-point edge. The school also maintains a stable 3-star state rating, ranking in the upper half of Connecticut high schools with a student-teacher ratio of just 9.6 to 1. This low class-size proxy, combined with per-student spending of $17,857, suggests strong instructional resources that likely contribute to these positive outcomes.

However, two areas deserve attention. Chronic absenteeism at The Morgan School is 18.1%, higher than both the district rate of 11.9% and the state rate of 16.4%, which could undermine academic progress even in a school with clear strengths. Math proficiency is also a relative weak spot: at 30.5%, it trails the state's 31.1% in 2024-2025, making it the only subject where the school lags. Despite nearly 40% of students qualifying for free or reduced-price lunch, the school still achieves above-state results in ELA and science. While the district overall lands in the 42nd percentile of Connecticut districts, The Morgan School itself ranks in the 59th percentile, reflecting stronger performance at the high school level. For parents, this is a solid, stable school with excellent graduation outcomes, strong literacy and science instruction, and a supportive learning environment—but one where improving math scores and reducing absenteeism remain key goals.
