Summary:
Middle-level schools in zip code 02478 (Belmont, MA) are two high-performing Belmont district schools: Winthrop L Chenery Upper Elementary (grades 4–6, enrollment 1,023) and Belmont Middle School (grades 7–8, enrollment 742), serving 1,765 students combined.
Both schools are standouts: both earned 5 stars in every reported ranking year. Belmont Middle ranked 11th of 478 (98th percentile) in 2025–2026, while Chenery’s latest rank was 5th of 501 (99th percentile) in 2022–2023, so their rank histories do not overlap. On 2025–2026 MCAS Next Generation all-grade tests, Belmont Middle scored 73.43% ELA, 74.68% math, 79.10% science, and 80.87% civics. Chenery scored 66.50% ELA, 71.83% math, and 72.94% science. All are far above state averages; for example, Belmont Middle’s civics is 80.87% vs. state 39.77%, and Chenery’s math is 71.83% vs. state 41.11%. Chenery has the lower student-teacher ratio (13.8 vs. 15.5).
Grade-level data matter here because the schools serve different grade bands. In 2025–2026, Chenery outperformed the district in every reported grade-level subject, so its all-grade average looks lower partly because the district comparison includes Belmont Middle’s grades 7–8. Chenery’s 6th grade is its strongest and 5th grade its weakest; Belmont Middle’s 8th grade outperforms its 7th. Belmont Middle slipped from 2024–2025 but remains very high, while Chenery improved in ELA and math but declined in science. Free/reduced-lunch data is unknown for both schools, so economic context cannot be assessed; Chenery’s only per-student spending figure is $14,953 (2020–2021), and Belmont Middle has none. No test scores here are suppressed or bounded.
