Summary
Greenwich School serves 397 students in prekindergarten through grade five in the Stewartsville area of Greenwich Township, New Jersey. Its latest results show a clear split: third grade is comparatively strong, while fourth grade and science stand out as concerns. Most importantly, the school’s average results are below the state in ELA, math, and fifth-grade science, with science showing the largest gap.
Third-grade math is a relative bright spot: 49% of students were proficient, about even with the state’s 49%, and Greenwich ranked third among nine nearby schools with results. Fourth grade is weaker: ELA proficiency was 34% and math was 33%, both ranking sixth among eight nearby schools with comparable results. Fifth-grade science was 16%, the second-lowest result among seven nearby schools; only Pohatcong Township School was lower, at 15%. Across tested grades, Greenwich averaged 43% in ELA and 41% in math, versus 49% and 47% statewide; science was 16% versus 27% statewide. Greenwich Township School District has a higher SchoolDigger rating than the school, but the supplied school and district test-score figures are identical, so they do not show a separate achievement comparison.
Results have weakened relative to the state over time: from 2022–2023 to 2025–2026, Greenwich’s average fell 9 points in ELA and 6 points in math, while fifth-grade science dropped 24 points. SchoolDigger rates Greenwich at the 38th percentile statewide, with 2 stars, down from the 54th percentile the prior year; the district is at the 53rd percentile with 3 stars. The school’s student-teacher ratio is 11:1, toward the high end among nearby schools. Its free/reduced lunch eligible share was 12% in 2024–2025, the lowest among nearby schools reporting that measure and year. SchoolDigger’s student-group rankings vary notably: it ranks at the 81st percentile for how well it serves Hispanic Students, up from 54 two years earlier, while its ranking for how well it serves White Students is at the 19th percentile.
