Summary

Hosmer is a PK–5 elementary school in Watertown, MA, serving 758 students, which makes it the largest elementary school among its nearby peers. It is part of Watertown Public Schools, a district ranked 110 of 351 statewide, the 69th percentile with 3 stars. Hosmer itself ranks 244 of 899 Massachusetts elementary schools in 2025–2026 — the 73rd percentile, with 4 stars — so it currently outranks its own district's standing.

Hosmer is a turnaround story: it sat at the 20th percentile statewide in 2016–2017 with 1 star and has climbed to a solidly above-average 4-star school, though the path has not been straight. In 2025–2026 MCAS results, 50.72% of students were proficient in ELA and 57.19% in math, both above the district and well above the state (40.03% ELA, 41.11% math). Math is the school's signature strength, with 3rd, 4th, and 5th grades all above the state. Science is the current weak spot at 51.85% proficient — above the state but below the district's 55.87%, a reversal from several years when science was a district strength. Because science is tested only in 5th grade here, it is a focused area to watch.

Compared with neighbors, Hosmer is close to same-district James Russell Lowell (72nd percentile) but with different subject profiles: Hosmer leads in ELA and math, while Lowell leads in science. Hosmer outscores Winship in ELA and math and far outperforms Boston's Edison and Lyon, but trails top schools in Belmont and Newton such as Underwood, Lincoln-Eliot, Daniel Butler, Roger E Wellington and Mary Lee Burbank. Spending is $24,179 per student with a 10.7 student-teacher ratio — more than Belmont and Newton neighbors, less than Boston and Cambridge ones — a reminder that spending alone does not determine outcomes. Results also vary across student groups: special education performance has improved sharply, and some groups rank above the median while others have softened recently.
