Elementary Schools in Plympton

Plympton is served by a single elementary school: Dennett Elementary, a K–6 school with 249 students in the Plympton district. Because Dennett is the only school in the district, the district's MCAS results and the school's results are identical, and there is no other local school to compare it against — the useful comparison is against Massachusetts as a whole.

Dennett is a high-performing school by state standards. In 2025–2026, 57.23% of students were proficient in English language arts, 56.60% in math, and 54.55% in science, compared with statewide rates of 40.03%, 41.11%, and 40.98%. That puts Dennett 17.20 points above the state in ELA, 15.49 points above in math, and 13.57 points above in science. Every reported grade and subject is above the state average. The standout result is grade 3 ELA, at 75.68% proficient versus 42.79% statewide, a gap of 32.89 points. Grade 6 math is another strength, at 60.87% versus 42.59% statewide. Dennett ranks 203rd of 899 Massachusetts elementary schools, in the 77th percentile with 4 stars.

Looking year over year, math improved notably, rising from 51.28% to 56.60% while the state barely moved, so the school's math advantage grew from +10.54 to +15.49 points. ELA slipped slightly, from 58.33% to 57.23%, but the state fell too, so Dennett's lead widened to +17.20 points. Science dropped from 65.22% to 54.55% with the state nearly flat, though it remains above average; since science is only reported for grade 5 here, this may reflect one cohort rather than a schoolwide trend. The school's rank improved from 242nd of 906 (73rd percentile) to 203rd of 899 (77th percentile). Other context: a 14.2 student-teacher ratio and $16,659 per-student spending in 2020–2021. Free/reduced-lunch data is blank, so economic context is unavailable, and with only 249 students, grade-level percentages can swing noticeably from year to year.
