There is no meaningful local top-to-bottom comparison because this is the only school in the ZIP-code list; it is therefore both the highest- and lowest-ranked locally, with a 0-point school-to-school range. Within the school, results vary by grade: fourth-grade math was especially strong at 78%, compared with 42% statewide, a 36-point advantage. Fifth-grade math was 51% versus 36% statewide, still ahead but by a smaller 15 points. ELA was above state results in grades 3, 4, and 5, with advantages of 19, 15, and 22 points, respectively.
Results are moving in different directions by subject. All-grade ELA rose from 61% in 2024–2025 to 72% in 2025–2026, and its state advantage widened by 7 points; math fell 3 points, while the school’s lead over the state narrowed by 4 points.
