High Schools in West Haven School District

West Haven School District is served by a single public high school, West Haven High School, which enrolls 1,813 students in grades 9–12 in the West Haven, CT area. As the only high school in the West Haven School District, this school’s performance defines high school education for the entire community, and its outcomes are compared against state averages rather than local peer schools.

The most encouraging sign is the graduation rate. In 2024–2025, 94.8% of students graduated, beating both the district rate of 93.3% and the state rate of 91.2%. However, academic proficiency tells a very different story. On the 11th-grade SAT, only 10.0% of students were proficient in math in 2025–2026, compared to 31.3% statewide, while ELA proficiency was 35.5% versus the state’s 55.3%. Science is the strongest tested subject — 47.0% proficient in 2025–2026, close to the state’s 50.5%, and actually above the state the previous year. Chronic absenteeism is a serious concern, with 26.1% of students chronically absent, far exceeding the state’s 16.4%. With more than half of students (52.2%) eligible for free or reduced-price lunch, this is a high-poverty school facing significant challenges.

The school’s overall ranking has improved from the 27th percentile (1 star) in 2023–2024 to the 33rd percentile (2 stars) in 2025–2026, though it remains below the midpoint of Connecticut high schools. The contrast between a graduation rate above the state average and math proficiency at just one-third of the state rate suggests students may be earning diplomas despite substantial academic skill gaps. Math stands out as the highest-priority area needing intervention, and addressing chronic absenteeism will likely be key to improving academic outcomes. Because the district and school are identical at the high school level, any district-wide improvement plan directly targets this one school. Overall, families should recognize both the real strength in graduation and science outcomes and the urgent need for growth in math, reading, and attendance.
