Summary:
ZIP code 02050 is home to five elementary schools serving about 1,636 students in the Marshfield district on the Massachusetts South Shore: Martinson Elementary, Gov Edward Winslow, Daniel Webster, South River, and Eames Way School. Four serve kindergarten through grade 5, while Daniel Webster also includes pre-kindergarten. Enrollment ranges from 249 students at Eames Way to 445 at Martinson. As a district, Marshfield ranks 104 of 351 statewide — the 70th percentile, with 4 stars — and its all-grade proficiency in ELA, math, and science sits above the state average in every subject.
Eames Way School is the standout, ranking 142 of 899 schools (84th percentile, 4 stars) with the group's highest ELA (60.95%) and math (71.03%) scores and a share of the top science score (55.56%). Gov Edward Winslow (74th percentile, 4 stars) and South River (73rd percentile, 4 stars) also outperform the district in all three subjects. Daniel Webster (67th percentile, 3 stars) is the most improved, gaining in ELA, math, and science year over year. Martinson Elementary (47th percentile, 2 stars) is the only school below the 50th percentile and trails the district in every subject.
Trends matter as much as snapshots. Daniel Webster is the only school that improved in all three all-grade subjects from 2024-2025 to 2025-2026, including a +13.18 point science jump. Martinson declined in all three, and South River's science fell 12.77 points after leading the group the prior year. Within schools, grade-level results swing widely — for example, Daniel Webster's 3rd grade ELA (73.33%) versus 5th grade ELA (22.50%) — which may reflect small cohorts and should be read cautiously. Per-student spending and student-teacher ratios show no simple relationship with outcomes. Free/reduced lunch data are unavailable for all five schools, so this analysis cannot address how socioeconomic factors relate to performance.
