Summary:
Zip code 02026 covers Dedham, MA, and contains five elementary schools in the Dedham district: four tested schools serving grades 1–5 — Avery, Greenlodge, Oakdale, and Riverdale — plus Early Childhood Center, which serves PK–K only. Enrollment across the five schools totals 1,394, with 1,109 students in the grade 1–5 schools. The district overall ranks 148 of 351 (58th percentile, 3 stars), but outcomes inside this zip code vary sharply.
Greenlodge and Oakdale are the academic standouts. Both hold 4 stars and rank in the top quarter of the state — Greenlodge at 174 of 899 (81st percentile) and Oakdale at 195 of 899 (78th percentile) — and both beat district and state averages in ELA, math, and science. Oakdale is the biggest riser, climbing from the 62nd to the 78th percentile in one year, and posts the highest all-grade ELA in the zip. Riverdale (58th percentile, 3 stars) has the top science score in the zip and the strongest 3rd grade reading and math, but its 4th grade results are the lowest of the four schools.
Avery is the clear outlier: 650 of 899, 28th percentile, 1 star, and below district and state averages in every all-grade and grade-level subject, with a decline from the mid-30s percentile. Science fell at all four tested schools year over year, which may reflect 5th-grade cohort changes rather than a school-wide trend. Notably, spending and class size do not track with performance: Oakdale has the lowest per-student spending and Greenlodge the highest student–teacher ratio among the grade schools, yet both lead. Free/reduced lunch data is not reported for any school, and Early Childhood Center cannot be compared on MCAS.
