Summary
Francis J Kane is a K–5 elementary school in Marlborough, MA, serving 575 students as part of the Marlborough district, which ranks 290th of 351 statewide (17th percentile, 1 star). Francis J Kane itself ranks 623rd of 899 Massachusetts elementary schools in 2025–2026 (31st percentile, 2 stars), placing it above its district overall but still in the lower third of the state. Its rank has shifted over time, from 46th percentile in 2021–2022 to 27th in 2024–2025 and back up to 31st in 2025–2026.
On 2025–2026 MCAS tests, Kane students were proficient at 31.58% in ELA, 28.63% in math, and 36.62% in science. All three are above the district average, but all three trail the state — math by the widest margin, 12.48 points. Science is the clear relative strength, 13.95 points above the district. By grade, 3rd-grade math is the weakest spot at 25.64%, below the district and 16.55 points under the state, while 5th-grade math (33.80%) runs 10.52 points above the district. Among Marlborough elementary schools, Kane beats Charles Jaworek School and Richer in all three subjects and roughly matches Goodnow Brothers Elementary School in ELA and math while leading in science. Neighboring schools in Hudson (Mulready Elementary, Forest Avenue Elementary), Framingham's Hemenway, and the Southborough schools (Albert S. Woodward Memorial School, Margaret A Neary) post much higher rates, with the Southborough schools in the 68–82% range.
Subgroup data show strain: special education students rank at the 43rd percentile statewide, but English Language Learner students (24th) and low-income students (23rd) sit far below their 2023–2024 levels. Resources are mid-range — the student-teacher ratio rose to 13.0, and per-student spending was $18,338, more than same-district peers Richer and Goodnow but less than Hemenway or Framingham's Brophy, which spends more yet performs lower. Overall, Kane is a solid performer within its district with a science highlight, but still has ground to make up in math and for several student groups.
