Summary
Morse is a PK–5 elementary school at 40 Granite Street in Cambridge, MA, serving 328 students. In 2025–2026, the school ranks 117th of 899 Massachusetts elementary schools — the 87th percentile with 4 stars — while the Cambridge district ranks 71st of 351 districts. The school has improved from the 50th percentile in 2017–2018 to 80th–87th in recent years. Its MCAS results are above district and state in English language arts, math, and science. Science is a clear standout: 65.31% proficiency, compared with 51.03% districtwide and 40.98% statewide. Math is also strong at 61.76%, above the district’s 57.29% and the state’s 41.11%.
Among the listed same-district schools, Morse ranks fourth of seven and sits in the stronger cluster with John M Tobin, Amigos School, and Martin Luther King Junior. It substantially outperforms King Open, Fletcher/Maynard Academy, and Cambridgeport in all three tested subjects. Math is where nearby high performers separate: John M Tobin (69.15%), Amigos School (68.40%), and Martin Luther King Junior (67.44%) score higher than the school (61.76%). Some nearby Brookline schools — Florida Ruffin Ridley School, Lawrence, and Pierce — also outperform the school in math and science, though it has higher ELA than that school. The school spends $35,553 per student (2020–21) and has a 10.1 student/teacher ratio, lower than many nearby schools but rising over three years.
Within the school, fourth grade is the clearest soft spot: 4th-grade ELA (56.10%) and math (57.14%) are below district averages, while 3rd and 5th grades are above district in every tested subject. That may reflect a specific cohort rather than a school-wide pattern. Effectiveness rankings for student groups are uneven. Special education students improved markedly, from the 56th percentile in 2023–24 to the 86th percentile in 2025–26. Low socio-economic status students rank at the 44th percentile in 2025–26, well below the school’s overall 87th-percentile rank — an equity area to watch. Overall, the school is high-performing and improving, with a signature strength in science; its main challenges are the 4th-grade dip and lower effectiveness ranking for low-income students.
