Summary

Coginchaug Regional High School is a small public high school in Durham, Connecticut, serving 356 students in grades 9 through 12 as part of Regional School District 13. The school ranks 23rd out of 133 Connecticut high schools for 2025-2026, placing it in the 83rd percentile with a 4-star rating. Students far outpace state averages: 77.5% of 11th graders are proficient in English language arts (vs. 55.3% statewide), and 74.2% are proficient in science (vs. 50.5% statewide). The school also has a very low chronic absenteeism rate of 8.7% — less than half the statewide 16.4% — plus an exceptional student-teacher ratio of 8.8:1 and per-pupil spending of $21,182.

Among nearby schools, only Haddam-Killingworth High School is a true peer, ranking 14th statewide. Coginchaug dramatically outpaces other regional high schools: its ELA proficiency of 77.5% compares favorably to Portland High School (57.7%), Lyman Hall High School (56.7%), and Francis T. Maloney High School (43.8%). Science proficiency is similarly strong at 74.2%, well above Lyman Hall (65.0%), Mark T. Sheehan High School (58.8%), and Portland (56.3%). With a free/reduced-price lunch rate of 15.7%, the school serves a comparatively advantaged population, and its chronic absenteeism is far below Middletown High School (34.6%) and Maloney (29.2%).

Science is a standout subject, with proficiency reaching 80.2% in 2022-2023 — about 33 points above the state average. The graduation rate of 92.5% is slightly above the state average but trails Haddam-Killingworth's 97.6%. Notably, Vinal Technical High School and H. C. Wilcox Technical High School graduate a higher share of students but score far lower on academic assessments. No SAT math proficiency score is reported for the school, which limits a full academic comparison. Attendance has recovered quickly from a pandemic spike of 19.8% in 2021-2022 back to 8.7%, and the school has earned 4 stars in most years over the past decade. Overall, Coginchaug is a well-resourced, high-performing school that stands out clearly from most of its regional neighbors.
