Summary:
ZIP code 02050 contains exactly one middle school — Furnace Brook Middle in Marshfield, MA — serving grades 6 through 8 to 799 students, so every middle-level statistic for this area describes this single campus rather than a comparison among schools. It belongs to the Marshfield district, which ranks 104th of 351 districts statewide (70th percentile) and holds a 4-star rating. The school's student–teacher ratio is 10.4:1, implying roughly 77 teaching staff, and per-student spending was $15,247 in 2020–2021. The free/reduced-lunch percentage is not reported in this data set, so the socioeconomic context of the student body is unknown.
Academically, Furnace Brook outperforms the Massachusetts average in every subject in both reported years. In 2025–2026 it posted 52.31% proficient in Math versus 41.11% statewide (+11.2 points), 45.71% in ELA versus 40.03% (+5.7), 44.67% in Science versus 40.98% (+3.7), and 40.89% in grade-8 Civics versus 39.77% (+1.1). Math is the clearest strength, leading the state at every grade level, with grade-6 math at 59.48%. ELA is the subject where the school is essentially indistinguishable from its district (45.71% versus 45.63%).
Two things temper that picture. First, the school's rank percentile has slid from 81 to 78 to 71 over three years even as its 4-star rating held steady, and ELA, Science, and Civics all fell faster than the state in the most recent year, with Civics dropping 10.3 points. Second, grade-7 ELA is the only below-state result in the data (34.56% versus 39.91%), and the district's grade-7 figure is nearly identical — pointing to a district-wide pattern rather than a school-specific one. Proficiency also declines from grade 6 to grade 8 in both core subjects.
