ELA proficiency rose from 76% in 2024–2025 to 79% in 2025–2026, but the state also improved, so the school’s lead narrowed by 1 point. Math rose by 1 point to 38%, remaining just below the state. Eighth-grade science shifted from 5 points above the state in 2024–2025 to 10 points below in 2025–2026. SchoolDigger’s ranking moved from the 78th percentile in 2024–2025 to the 62nd in 2025–2026, a 16-point decline, even as all-grade ELA and math scores rose; its comparison group also changed. For context, 47% of students were eligible for free or reduced-price lunch in 2024–2025, and the student-teacher ratio was 11.7 that year. These figures describe the school, but cannot establish a relationship between student context and achievement.
