Summary
Joseph Estabrook is a K–5 elementary school serving about 490 students in Lexington, MA, part of Lexington Public Schools, a district ranked 6th of 351 in Massachusetts (98th percentile, 5 stars). In 2025–2026, Estabrook itself ranked 18th of 899 elementary schools statewide — 98th percentile, 5 stars — and its record is remarkably stable: 5 stars every year shown, moving from ranks of 68–95 in 2015–2019 to 14–40 in recent years. That shift suggests a school that has moved from the top 10% to a consistent top-2% to top-4% statewide. On 2025–2026 MCAS Next Generation all-grade proficiency, Estabrook scored 71.73% in ELA, 80.92% in math, and 79.05% in science, far above state averages of 40.03%, 41.11%, and 40.98%.
Estabrook is the highest-ranked school among its same-district Lexington peers: 18th versus Bridge at 20, Maria Hastings at 32, Harrington at 52, and Fiske at 68. STEM is the signature strength — math and science results lead every nearby school. ELA is excellent but slightly less dominant: Bridge edges Estabrook at 74.59, and the district average of 72.94 is a touch higher. The strongest grades are 4 and 5, where Estabrook posts the best peer scores in 4th grade math (85.71), 5th grade math (83.81), 5th grade ELA (78.10), and 5th grade science (79.05). The relative soft spot is 3rd grade, where ELA (66.25) and math (71.25) fall below district averages — worth monitoring, though it looks more like a cohort or transition issue than a school-wide decline. The closest non-Lexington peer, Bedford's Lt Job Lane School, trails well behind in math (68.24) and science (69.47).
Subgroup results show the school is effective beyond its already-high averages: English Language Learner students ranked 1st of 282, 1st of 264, and 1st of 267 statewide across three years, and special education students ranked 21st of 709 (97th percentile) in 2025–2026. Estabrook also gets these results with comparatively modest resources — per-pupil spending of $18,214 in 2020–2021 was the lowest among nearby schools with data, and its student-teacher ratio of 11.2 in 2024–2025 is higher than every Lexington peer. The main caution is data gaps: some subgroup figures are old, and free/reduced lunch data were unavailable, so economic context cannot be fully assessed.
