Summary:
Elementary schools in zip code 02472 — Watertown, Massachusetts — consist of three public schools serving grades PK–5: Hosmer (758 students), James Russell Lowell (422), and Cunniff (320), together enrolling about 1,500 students in the Watertown district, which ranks 110th of 351 Massachusetts districts.
Academically, Hosmer posts the strongest 2025–2026 all-grade results in English language arts (50.72%) and math (57.19%), along with the best current rank (244th of 899, 4 stars). James Russell Lowell ranks close behind at 251st and leads in science at 64.71%, the highest single subject score in the group, and has held 4 stars in each of the last three years. Cunniff, the smallest school, has the lowest student-teacher ratio (8.0) and the highest per-student spending ($24,988), but the lowest all-grade ELA and math proficiency and a 3-star ranking (324th).
All three schools exceed the state average in every tested subject, though ELA is the weakest area across the group. Science splits the schools most sharply: James Russell Lowell and Cunniff are above the district average, while Hosmer trails it. Cunniff's 4th-grade ELA result of 32.00% is the only reported grade-level score below the comparable state figure. Free/reduced-lunch percentages are blank for all three schools, so economic-disadvantage comparisons cannot be made.
