Class sizes are favorable: student-teacher ratios are 9.4 at the middle school, 9.8 at the high school, and 11.0 at Chickering. Per-student spending in 2020–2021 was $21,791, $21,388, and $20,711 respectively — a range of only about $1,080. Science declined at every school from 2024–2025 to 2025–2026 (−3.91 high, −5.69 middle, −2.78 Chickering), while math rose at the elementary (+5.90) and middle (+3.47) levels and dipped only slightly at the high school (−1.08). Even the smallest school-to-state gap, middle-school science at +24.93 points, remains far above state averages. Free/reduced-lunch data is blank for all three schools, so equity comparisons are not possible from this dataset.
