Summary
Old Hammondtown is a small public school in Mattapoisett, MA — a coastal town in the Old Rochester regional attendance area — serving grades 4 through 6 with 154 students, about 50 per grade. It is the tested school of the Mattapoisett district, and its students move on to a regional junior high for grades 7–8 nearby.
Academically, Old Hammondtown sits at the top of its local field. In 2025–26 it outperformed every nearby school in all three subjects: 59.86% proficient in ELA, 57.43% in math, and 80.00% in science — margins of +25.9, +21.9, and +47.0 points over the nearby averages. Science is a genuine standout, more than double the state rate (40.98%) and well ahead of the next-best school, Freetown-Lakeville Middle School (49.58%). The school has beaten the state in all 12 subject-year combinations over four years. Two watch items: math has slipped three straight years (69.82% in 2023–24 down to 57.43%), and 4th grade is the weakest link (42.86% ELA, 50.00% math), while 6th grade ELA (73.91%) is the highest grade-level result in the whole comparison set.
Resources are unusually strong. At 9.6 students per teacher, Old Hammondtown has the smallest classes among its neighbors, and at $21,694 per pupil it spends about 27% above the nearby average. Notably, Old Rochester Regional Junior High, the school its students feed into, posts lower results (50.00% ELA, 39.07% math, 41.58% science) — though the grade bands and science tests differ. With roughly 50 students per grade, each student moves results by about 2 points, so single-year swings deserve less weight than consistent trends. Free/reduced-price lunch data is suppressed for this school and every peer, so economic context can't be compared here.
