Summary
Avery is a public elementary school serving grades 1 through 5 in Dedham, Massachusetts, a Boston-area community, with 321 students. Its district, Dedham, ranks 148th of 351 districts statewide (58th percentile, 3 stars), but Avery itself ranks 650th of 899 Massachusetts elementary schools in 2025–2026 — the 28th percentile, with 1 star. Enrollment is similar to Greenlodge (320) and larger than Oakdale (262) and Riverdale (206).
In 2025–2026, 28.88% of Avery students met expectations in ELA, 29.41% in math, and 26.39% in science — below the Dedham district (45.03%, 48.84%, 34.34%) and the state (40.03%, 41.11%, 40.98%). Every tested grade and subject is below district averages, so the weakness is broad rather than isolated. Avery is the lowest-performing grade 1–5 elementary in Dedham: Greenlodge (58.56% ELA, 65.19% math) and Oakdale (58.67%, 60.00%) are 4-star schools, and Riverdale is 3-star. Math shows the widest gap — roughly 30 points below Oakdale and 36 below Greenlodge. Among nearby Boston schools, Avery outperforms Boston Renaissance Charter, Roosevelt K-8, and Channing, but trails Grew Elementary.
After several years in the low-to-mid 30s percentile, Avery fell to the 28th percentile and 1 star in 2025–2026, with ELA and math at their lowest points in four years and science fluctuating. School-effectiveness results for student groups are uneven — special education students dropped from the 57th to the 33rd percentile, and low-income students remain in the bottom quartile. Class size and spending do not obviously explain the gap: Avery's student-teacher ratio (10.2) is more favorable than Greenlodge's and Oakdale's, and it spent more per student than both. The key question for next year is whether 2025–2026 is a one-year dip or the start of a longer decline.
