Summary

Guilford High School serves 1,008 students in grades 9–12 in Guilford, CT, a suburban shoreline community. The school ranks 20th of 133 Connecticut high schools (85th percentile, 4 stars) and has been a top-20% school statewide for over a decade. Guilford's academics are well above state averages: 80.5% of 11th graders are proficient in SAT ELA (vs. 55.3% statewide), 53.5% in math (vs. 31.3%), and 67.5% in science (vs. 50.5%). The graduation rate is 96.7%, compared to 91.2% statewide.

Among nearby schools, Guilford ranks second only to Daniel Hand High School in Madison, which sits at 8th statewide. Guilford essentially ties Daniel Hand in ELA (80.5% vs. 80.2%) and posts a similar graduation rate, but Daniel Hand is ahead in math (66.1% vs. 53.5%), science (77.3% vs. 67.5%), and attendance. Math is Guilford's clearest academic weakness: proficiency has slipped from 63.5% in 2022–2023 to 53.5% in 2025–2026. Chronic absenteeism is also a concern at 13.2% — higher than the Guilford School District average of 8.9% and far above Daniel Hand's 5.2%, though still better than the state average of 16.4%. Other regional schools, including North Haven High School, Lyman Hall High School, and East Haven High School, all trail Guilford in ranking and proficiency.

Guilford serves a relatively affluent community — 14.6% of students qualify for free or reduced-price lunch — and the school's low-income students perform in the top 10% of schools statewide, a meaningful equity strength. The school also achieves strong results without the highest spending in the region: per-pupil spending is $18,213, and the student-teacher ratio is 11.8. Guilford is a reliable, high-performing school and a clear bright spot within its district, but math achievement and attendance are the two areas families will want to watch in the coming years.
