Academically, the school is high-performing with a standout science program. The district is ranked 19 out of 351 in Massachusetts, placing it in the 95th percentile with 5 stars. The school’s own rank was 119 of 899 (87th percentile, 4 stars) in 2025–26, 71 of 906 (92nd percentile, 5 stars) in 2024–25, and 118 of 916 (87th percentile, 4 stars) in 2023–24. In 2025–26 MCAS all-grade proficiency, it scored 60.4 in English language arts, 63.55 in math, and 77.05 in science, compared with state rates of 40.03, 41.11, and 40.98. That puts the school far above the state in all three subjects; science is about 36 points above the state and slightly above the district, while ELA and math are slightly below the district. Year over year, the school declined in ELA (−7.26 points), math (−5.26 points), and science (−9.44 points), even as the state was roughly flat and the district improved slightly in math.

At the grade level, the school generally tracks the district very closely, usually within about 1 point. The strongest single result is 5th-grade science at 77.05. The lowest core result is 5th-grade ELA at 52.46, though it is still 14.31 points above the state. Math is strongest in 4th grade (70.42) and weakest in 3rd grade (59.15), while ELA is strongest in 3rd grade (67.14) and weakest in 5th grade (52.46). Other context: the student-teacher ratio is 13.4, per-student spending in 2020–21 was $19,599, and free/reduced lunch data is not reported. Overall, the school remains a top-tier Massachusetts elementary school, with science as its clearest strength and 5th-grade ELA as the relative area to watch; single-year changes can reflect cohort differences, and the missing free/reduced lunch data limits socioeconomic context.
