Summary:
Zip code 01886 covers Westford, Massachusetts, where six elementary schools enroll about 1,984 students in two grade bands — three PK–2 schools and three grades 3–5 schools — all within the Westford district, which ranks 38th of 351 in Massachusetts at the 89th percentile with 4 stars.
Academic results are available only for the grades 3–5 schools, since state testing begins in grade 3. Abbot Elementary is the clear standout: it ranks 92 of 899 (90th percentile) in 2025–2026, up from 121 of 916 three years earlier, and it is the only tested school above the district in all three subjects (ELA 60.17%, math 70.06%, science 73.91%). John A. Crisafulli Elementary School and Day Elementary both still beat the state in every subject, but their rankings have slipped — Crisafulli from 122 to 196 of 899, and Day from 146 to 199 — and they trail the district in most subjects. Three years ago Abbot and Crisafulli were essentially tied; Abbot is now roughly 104–107 ranks ahead of the other two.
On resources, Rita E. Miller Elementary School is the outlier, with the lowest student-teacher ratio (10) and the highest per-student spending ($18,644 in 2020–2021). Abbot has the largest enrollment (371) yet the lowest reported spending ($15,235), the most striking contrast in the data. The other PK–2 schools, Col John Robinson and Nabnasset, can be compared only on enrollment, staffing and spending. Note that PK–2 schools have no MCAS results, free/reduced-lunch data is unavailable for all six, and spending figures are from 2020–2021 while test scores are more recent.
