Summary:
Winthrop has one public middle school, Winthrop Middle School, serving grades 6–8 in Winthrop, Massachusetts, a coastal community near Boston. The school enrolls 439 students at 60 Payson Street and is part of the Winthrop district. Its ranking has been stable and above average: 4 stars and a 73rd–74th percentile position for three reported years, including 127 out of 478 in 2025–2026, 128 out of 484 in 2024–2025, and 129 out of 493 in 2023–2024.
Academically, ELA and mathematics are clear strengths. In 2025–2026 MCAS Next Generation results, all-grade ELA proficiency was 51.93% versus the state’s 40.03%, and all-grade mathematics was 53.78% versus 41.11%. Grade 7 ELA reached 60.00%, more than 20 points above the state, while Grade 8 mathematics was 58.70%, about 17 points above. Science is the relative weak spot: all-grade science was 36.96%, below the state’s 40.98%, and Grade 8 science was 36.96% versus 38.93%. Grade 8 Civics improved from 36.49% to 40.58%, slightly above district and state. All-grade ELA declined from 56.00% to 51.93% year over year, but it remains about 12 points above the state; mathematics and science improved slightly.
Other data show a student-teacher ratio of 13.2 in 2024–2025 and per-student spending of $14,570 from 2020–2021, though no state or district ratio is provided for direct comparison. The school’s 4-star, 73rd-percentile profile is notably stronger than the Winthrop district overall, which is listed at the 42nd percentile with 2 stars. For parents, the takeaway is a stable, above-average middle school with strong ELA and mathematics results, a persistent science gap to watch, and a recently improving Civics outcome.
