Summary
Martinson Elementary is a K–5 school with 445 students in Marshfield, MA, a coastal South Shore town, part of the Marshfield district, which is rated 104th of 351 districts in Massachusetts (70th percentile, 4 stars). Martinson's own rating is far lower: in 2025–2026 it ranks 474th of 899 elementary schools statewide, at the 47th percentile with 2 stars. Its latest MCAS Next Generation proficiency rates are 35.14% in ELA, 46.61% in math, and 34.38% in science, below the district in all three subjects. Math is above the state's 41.11%, but ELA and science fall below their state averages of 40.03% and 40.98%.
The school's ranking has slid for years, and the latest year was a sharp break. Martinson dropped from the 64th percentile and 3 stars in 2024–2025 to the 47th percentile and 2 stars in 2025–2026, with all-grade proficiency falling 12.69 points in ELA, 8.61 points in math, and 11.96 points in science. Back in 2018–2019 it ranked 123rd of 942 schools, at the 87th percentile. Subgroup results are uneven: Special Education students rank at the 69th percentile, above the school overall, while the low-socioeconomic-status subgroup fell from the 88th percentile and 4 stars in 2023–2024 to the 40th percentile and 2 stars in 2025–2026.
Among Marshfield elementary schools, Martinson has the largest enrollment but the lowest rank and lowest all-grade scores. Eames Way School ranks at the 84th percentile with 60.95% in ELA, 71.03% in math, and 55.56% in science, and Gov Edward Winslow, Daniel Webster, and South River also outscore Martinson in every subject. Outside the district, Hobomock Elementary in Pembroke leads Martinson in all three subjects, and Alden School (Duxbury), William G Vinal (Norwell), and Center Elementary (Hanover) all score higher. Resources do not look like the limiting factor: Martinson's student-teacher ratio of 11.7 is lower than several peers, and its 2020–2021 per-student spending of $16,897 was relatively high, though that spending data is older and cannot be tied directly to current results.
