Summary
The Morgan School is a public high school in Clinton, Connecticut, serving 473 students in grades 9–12 as part of the Clinton School District. In 2025–2026, the school ranked 54th out of 133 high schools statewide, placing it in the 59th percentile with a solid 3-star rating. Over the past decade, Morgan has been a steady mid-tier performer, with its best recent showing in 2021–2022 when it ranked 39th in the state. The school sits in a competitive shoreline region surrounded by some of Connecticut's strongest high schools, including Daniel Hand High School, Guilford High School, and Lyme-Old Lyme High School.
Morgan's greatest strengths are its graduation rate and its support for students who often face the biggest barriers. In 2024–2025, 97.5% of students graduated, well above the state average of 91.2% and comparable to top regional schools like Daniel Hand (98.4%) and Haddam-Killingworth High School (97.6%). The school also exceeds state averages in ELA and science proficiency. Notably, in 2020–2021, Morgan's special education students ranked in the 91st percentile statewide, and its low-income students ranked in the 85th percentile — exceptional results. This is especially meaningful given that 40% of students now qualify for free or reduced-price lunch, more than double the rate at nearby Haddam-Killingworth (13.7%) and Daniel Hand (5.5%).
The school's most significant challenges are chronic absenteeism and math achievement. Morgan's chronic absenteeism rate stands at 18.1%, higher than the state average of 16.4% and far above nearby schools like Old Saybrook Senior High School (6.0%), Haddam-Killingworth (6.9%), and Daniel Hand (5.2%). Math proficiency is the clearest academic gap: only 30.5% of 11th graders were proficient in 2024–2025, below the state average and dramatically lower than Lyme-Old Lyme (70.9%), Daniel Hand (66.1%), and Guilford (57.3%). At $17,857 per student, Morgan also spends less than most neighboring high schools, yet still achieves strong graduation rates and above-average reading and science scores. Reducing absenteeism could be the single most impactful lever for improving math outcomes and raising the school's already-solid statewide standing.
