Summary:
ZIP code 01330 is served by a single public school, Sanderson Academy, an elementary school in Ashfield serving grades PK–6 with 125 students as part of the Mohawk Trail district; because it is the only school in the ZIP, local public education data ends at grade 6, with no middle or high schools in the area.
Sanderson Academy stands out most for its mathematics results. In 2025–2026, all-grade math proficiency was 56.25%, which is 25.73 points above the Mohawk Trail district and 15.14 points above the state. Sixth-grade math reached 78.57% proficient — nearly 36 points above the state — while 3rd and 5th grade math also beat both district and state. Science is strong as well: all-grade science was 45.45% proficient, about 24 points above the district and 4.47 points above the state. English Language Arts is more uneven. All-grade ELA was 41.67%, only 1.64 points above the state, and results range from 57.14% in 6th grade to 20% in 4th grade, the school's weakest result and below both district and state. The school's ranking has improved nonetheless, moving from the 50th to the 55th to the 61st percentile over the last three school years — a better trajectory than the district's overall standing of 235th of 351 districts (33rd percentile, 2 stars).
Context matters here: this is a small school with a student-teacher ratio of 12.3 in 2024–2025 and per-student spending of $25,439 in 2020–2021. The free/reduced lunch percentage for 2024–2025 is not available, so socioeconomic context is missing. Overall, families can see a small, improving elementary school that consistently outperforms its district, with real strength in math and science and continued room to grow in 4th grade ELA.
