Summary:
ZIP code 02664 has one middle school, Dennis-Yarmouth Middle School in South Yarmouth, MA, serving grades 6–7 with 477 students in the Dennis-Yarmouth district. Because it is the only middle school in the ZIP code, there are no same-ZIP peers; the useful comparisons are with its district, the state, and its own trends.
In 2025–2026 MCAS, all-grades ELA proficiency was 32.52% at the school, versus 30.31% in the district and 40.03% statewide. All-grades math was 30.65%, versus 34.56% in the district and 41.11% statewide. Grade 6 was stronger: ELA was 37.74% versus 36.99% district and 40.26% state; math was 39.32% versus 38.79% district and 42.59% state.

The school’s latest rank is 272 of 478 middle schools, or the 43rd percentile, with 2 stars; the district has 1 star and ranks in the 24th percentile. From 2024–2025 to 2025–2026, ELA fell 5.35 points (37.87% to 32.52%), while math rose 0.74 points (29.91% to 30.65%). District ELA fell 2.37 points and state ELA fell 1.50 points; district math rose 1.79 points and state math rose 0.37 points, so the school’s ELA decline was steeper and its math gain smaller than the district’s. Rank moved from the 34th percentile in 2023–2024 to 48th in 2024–2025 to 43rd in 2025–2026, staying at 2 stars. Student-teacher ratio is 10.5, per-student spending was $21,467 in 2020–2021, and free/reduced-lunch data is blank, so it is unknown. Grade 7 math is the clearest concern.
