ELA was 7 points below the state and 14 points below the district. Grade-specific results offer a more favorable comparison in 10th-grade math: 39% was 2 points above the state and equal to the district; 10th-grade ELA was 39%, equal to the district and 2 points below the state. SchoolDigger gives the school a 2025–26 rank of 202 out of 340, at the 41st percentile, with 2 stars.

ELA improved while the math gap with the state widened. From 2024–25 to 2025–26, ELA rose from 34% to 39%, a 4-point gain, and its gap with the state narrowed by 3 points. Math rose from 38% to 39%, but the state’s faster increase meant the gap widened by 1 point. Meanwhile, SchoolDigger’s percentile fell from 51st in 2024–25 and 50th in 2023–24 to 41st in 2025–26. Other indicators compare more favorably with the state: graduation was 91% versus 90%, dropout was 0.8% versus 1.2%, and chronic absenteeism was 12% versus 18%; absenteeism was 5 points higher than the district’s. The school’s student–teacher ratio is 12.4, and its free/reduced-lunch rate was 31% in 2024–25. With only one school and two years of ELA and math results, these figures cannot show local school-to-school differences or explain changes in the overall ranking.
