New Canaan High School

New Canaan High School is a highly regarded four-year public high school in New Canaan, Connecticut, serving about 1,257 students in grades 9–12 as part of the top-rated New Canaan School District. For over a decade, it has ranked among Connecticut's best schools, most recently earning #4 in the state for 2025–2026 (97th percentile) after three consecutive years at #1. Students far exceed state averages on 11th-grade assessments: 90.2% proficiency in English language arts (state: 55.3%), 73.1% in math (state: 31.3%), and 83.3% in science (state: 50.5%). The school also posts a 99.1% graduation rate and a 4.6% chronic absenteeism rate—well above and below the respective state averages.

Nearby comparisons show just how impressive these numbers are. Darien High School, less than 3 miles away, edges New Canaan slightly in ELA (91.4%) and math (77.2%), but New Canaan leads in science (83.3% vs. 75.8%). Wilton High School posts a slightly higher science score, but New Canaan holds the better overall ranking. The gap widens dramatically when compared to Stamford and Norwalk high schools—Westhill High School scores 51% in ELA and 21.1% in math, while Norwalk High School scores 41.7% and 20.2%—a roughly 40–50 point gap that mirrors differences in household income and school funding.

The school's excellence extends broadly across learners: it ranks #1 among Connecticut schools for Hispanic students, #2 for female students, and #2 for disabled students (in its most recent reported years). The slight drop from #1 to #4 in 2025–2026 is a minor shift, not a real decline, and the school remains comfortably within the top 3% statewide. With per-student spending of $22,594, a 12.2:1 student-teacher ratio, and a free/reduced-price lunch rate near zero, these outcomes reflect a mix of strong school support systems and a distinctly affluent community—context worth keeping in mind when evaluating the school against neighboring districts serving higher-poverty populations.
