Summary

John B. Sliney School is a PK–4 elementary school in Branford, CT, serving 252 students. It is part of the Branford School District, which ranks 83rd of 153 Connecticut districts, and the school itself ranks 204th of 491 Connecticut elementary schools — 58th percentile, 3 stars — placing it solidly in the middle tier statewide. Sliney also serves a relatively high share of economically disadvantaged students, with 47.2% eligible for free/reduced-price lunch in 2024–2025. One of its most distinctive features is an exceptionally low student-teacher ratio of 8.8:1, the lowest among all nearby schools, compared with 10.3 at Mary T. Murphy School and 11.8 at Mary R. Tisko School.

Chronic absenteeism is another area of real strength. Sliney cut its rate from 20.1% in 2021–2022 to just 10.9% in 2025–2026, well below the state average of 16.4%. Reading and language arts are consistently above state averages: 4th-grade SBAC ELA hit 67.3% in 2024–2025, and 3rd-grade ELA was 58.2% in 2025–2026 versus 47.3% statewide — an 8–20 point advantage over several consecutive years. Perhaps the most distinctive signal, though, is how the school supports its most vulnerable students: in 2020–2021, Sliney ranked in the 87th percentile statewide for low-income students and the 72nd percentile for special education students, placing it in the top tier of the state for both of those groups.

Math performance is more uneven. Sliney generally beats state averages but has trailed its own district in recent 3rd-grade results, reaching 60.0% proficiency versus 68.5% for the district in 2025–2026. Within Branford, Mary R. Tisko School posts much stronger math scores (78%+ proficient), yet Tisko also serves a far higher-income population, with only 17.8% of students eligible for free/reduced lunch compared with Sliney's 47.2%. Against nearby East Haven schools, Sliney stands out clearly — 3rd-grade ELA was 58.2% versus 32% or lower at Momauguin School and Grove J. Tuttle School. With per-pupil spending of $19,675 — higher than any nearby school — Sliney visibly invests in staffing and supports, and the payoff shows up in strong reading results, excellent attendance, and exceptional outcomes for economically disadvantaged and special education students.
