The student-teacher ratio is 14.5 for 2024–2025, and per-student spending was $15,628 in 2020–2021.

Academically, the school trails state averages in every current all-grade subject. In 2025–2026, math was the weakest area at 21.05% proficient versus 41.11% statewide — only about 51% of the state average — while ELA was 25.76% versus 40.03% and science was 27.94% versus 40.98%. The clearest bright spot is 7th grade ELA, at 40.00% proficient versus the state's 39.91%, the only current grade and subject at or above the state benchmark. 7th grade math (26.67%) and 5th grade science (31.82%) have the narrowest gaps in their subjects. The lowest current result is 5th grade math, at 13.64% versus 39.50% state, a gap of -25.86 points. Eighth grade is a consistent concern: ELA, math, and civics all sit at 16.67% proficient, with science at 20.83%.

Trends are mostly negative. The school's rank percentile slipped from 32 in 2023–2024 to 24 in 2024–2025 and 19 in 2025–2026. Science fell from 35.53% proficient in 2024–2025 (5.98 points below state) to 27.94% (13.04 points below), and 8th grade civics dropped sharply from 34.38% to 16.67% while the state average rose slightly. The only academic improvement was a small math gain of +0.87 points, which did not meaningfully close the gap. Grade-level results also swing more widely than the state's, and with only 356 students in K–8, a few students can shift a percentage substantially. Families should track grade-level cohorts over multiple years before drawing firm conclusions, and note that spending data is from 2020–2021.
