Summary
Day Elementary is a grade 3–5 school in Westford, MA, serving 299 students as part of the Westford Public Schools district, which ranks 38th of 351 districts statewide. In 2025–2026, Day ranked 199th of 899 elementary schools statewide — 78th percentile, 4 stars — so it remains above average but sits below its district’s overall standing.
In 2025–2026 MCAS Next Generation results, Day’s all-grade proficiency was 50.53% in English language arts, 61.57% in math, and 62.50% in science. That is above Massachusetts in all three subjects, but below the Westford district in all three, with gaps of roughly 5–7 percentage points. Grade-level results show relative strengths in grade 3 and grade 4 math, where Day slightly exceeds the district. The clearest weak spots are grade 4 ELA (43.88% vs. the district’s 51.10%), grade 5 math (59.18% vs. 67.42%), and grade 5 science (62.50% vs. 68.93%). Among nearby comparable schools, Abbot Elementary outperforms Day in all three subjects and ranks in the 90th percentile statewide, while John A. Crisafulli Elementary School and Russell St Elementary are close to Day overall; Day is well ahead of Page Hilltop Elementary School and Tyngsborough Elementary.
Day’s longer-term trend is important: it ranked in the 94th–98th percentile from 2015–2016 through 2018–2019, but its percentile has fallen into the high 70s. The school has 299 students, a student–teacher ratio of 13.0, and per-student spending of $15,916. Its class size is similar to nearby Westford grade 3–5 schools, and it spends more per student than Abbot, yet Abbot currently posts stronger results — so resources alone do not explain the gap. Subgroup effectiveness rankings are uneven, with very high results for English Language Learner and low-SES students, but the analysis cautions that subgroup sizes are not provided and small groups can swing widely. Free/reduced-price lunch data were not reported, and single-year changes can be volatile. Overall, Day is still a solid, above-state school that has slipped relative to its district and its former self.
