Summary:
ZIP code 02367 covers Plympton, MA, and contains just one public school: Dennett Elementary, a K–6 school with 249 students in the single-school Plympton district. The area has one elementary school and no middle, high, or alternative schools, so the local data trail for families ends at grade 6. Dennett ranks 203rd of 899 ranked Massachusetts schools in 2025‑26 — the 77th percentile, 4 stars, or the top quarter of the state. Its district ranking is 75th of 351, also 4 stars.
Dennett outperforms the state in every reported comparison. All-grades proficiency in 2025‑26 was 57.23% in ELA (state 40.03%), 56.60% in math (state 41.11%), and 54.55% in science (state 40.98%). Every tested grade — 3 through 6 — also landed above state averages in ELA and math, and grade 5 exceeded the state in science. Grade 3 ELA, at 75.68%, is the highest figure in the entire data set, roughly 33 points above the state. Grade 6 math, at 60.87%, is the school's best math grade, though that same grade posted its lowest result in ELA at 47.83% — still above the state, but the narrowest margin anywhere. Math drove the school's upward move: it gained 5.32 points year over year while the state rose only 0.37, helping lift Dennett 39 spots in the rankings from 2024‑25 to 2025‑26. The distance between its best and weakest subject shrank from 13.9 points to just 2.7.
One important caveat for parents: with 249 students across K–6, individual grades are small, so year-to-year swings of 5–10 points can reflect which students are in the room rather than a change in teaching. Science, tested only in grade 5, is the clearest example. Per-student spending of $16,659 comes from 2020‑21 and is historical context only, and free/reduced lunch data is not reported here.
