Summary

North Haven High School is a highly rated public high school in North Haven, CT, serving 944 students in grades 9–12 as part of the North Haven School District. The school has shown a clear and steady upward trajectory over the past five years, climbing from the 60th percentile to the 75th percentile in statewide rankings and earning a 4-star rating. It now ranks 33rd out of 133 Connecticut high schools, making it the top-performing traditional public high school in its immediate area.

Academically, North Haven outpaces every nearby school with available data in all tested subjects. In 11th grade, 66.7% of students met proficiency in ELA and 73.6% in science, well above the state averages of 55.3% and 50.5%, respectively. Its science achievement is a particular standout, running more than 20 points above the state. Math proficiency, at 43.2%, is the relative weak spot but still comfortably exceeds both the state (31.3%) and nearby peers like Lyman Hall High School (29.5%) and North Branford High School (33.3%). The graduation rate is an impressive 96.8%, well above the state average of 91.2%, and chronic absenteeism at 12.8% remains lower than most neighboring schools, though it ticked upward from the prior year.

What truly distinguishes North Haven is its exceptional results for students from low-income families, ranking 9th statewide among that subgroup. The school also keeps class sizes reasonable with an 11.0 student-teacher ratio and serves a student body with the lowest free/reduced-price lunch rate (24.15%) in its comparison group. While overall performance is strong, special education outcomes have declined sharply in recent years, and the attendance uptick is worth monitoring. Still, with sustained improvement, standout science programming, and strong equity outcomes, North Haven has firmly established itself as one of the region's leading public high schools.
