Summary
Furnace Brook Middle is a grades 6–8 school with 799 students in Marshfield, MA, part of the Marshfield district, which ranks 104th of 351 districts statewide (70th percentile, 4 stars). The school ranks 141st of 478 Massachusetts middle schools for 2025–2026, placing it in the 71st percentile with 4 stars. That is a meaningful drop: it peaked at 62nd of 487 (87th percentile) in 2016–2017 and was still 91st of 501 (82nd percentile) in 2022–2023, then fell to 93rd, 107th, and 141st — a loss of 50 rank positions and 11 percentile points in three years. Proficiency still exceeds state averages in ELA (45.71% vs. 40.03%), Math (52.31% vs. 41.11%), Science (44.67% vs. 40.98%), and 8th grade Civics (40.89% vs. 39.77%), though the school trails its own district in Math and Science.
Locally, Furnace Brook sits in the middle of its peer group. It outranks John W Rogers Middle, Hanson Middle School, Pembroke Community Middle School, and Silver Lake Regional Middle School, but trails Hingham Middle School, Cohasset Middle School, Norwell Middle School, Hanover Middle, Gates Middle School, and Duxbury Middle. Math is its comparative strong suit, and 6th grade Math is a standout at 59.48% proficient. Weak spots are 7th grade ELA (34.56%, below the state's 39.91%) and 8th grade Civics, which is only slightly above the state and behind eight nearby schools — even some ranked below it.
Staffing looks favorable: the student-teacher ratio is 10.4, lower than most nearby schools, and per-student spending of $15,247 (2020–2021) is the second-lowest in the comparison group, above only Hanover — mid-pack results on lean resources. The school serves low-income and special education students relatively well statewide (72nd and 78th percentiles, 4 stars), though those figures have dipped recently too. Overall: solid and above state average, but with a declining rank, uneven grade-level results, and a growing gap with the top nearby districts.
