Summary:
ZIP code 01056 covers Ludlow, Massachusetts, where two elementary schools serve a combined 961 students: Harris Brook Elementary School (grades 2–5, 593 students) and East Street Elementary School (grades PK–1, 368 students). The two schools divide the elementary years rather than overlapping them — East Street serves the earliest grades, and Harris Brook picks up from grade 2 — so most families move from one to the other. Both belong to the Ludlow district, which ranks 262 out of 351 districts statewide, at the 25th percentile with 1 star.
Only Harris Brook has state test results, because MCAS testing begins in grade 3. In 2025–26 its proficiency was below state in every subject: 22.09% in ELA (17.94 points below state), 27.36% in mathematics (13.75 points below), and 20.28% in science (20.70 points below). Science was both the largest gap and the steepest decline, falling 7.85 points from 28.13% the year before; mathematics dropped 5.53 points and ELA 2.41 points. Grade 4 mathematics was the relative bright spot at 36.11%, nearly matching the district's 36.24%. Grade 5 was the weakest tested grade, at 14.48% in ELA, 17.12% in mathematics, and 20.28% in science. Harris Brook has held a 1-star rating for three straight years, and its 2025–26 percentile of 19 is the lowest of the three.
East Street shows no test scores in this data, which reflects its PK–1 grade span rather than performance. Its student-teacher ratio is 11.8 versus Harris Brook's 11.1, a modest difference across different grade levels. East Street's per-student spending is listed at $18,352 (2020–21), while Harris Brook has no spending figure, so the two are not directly comparable. Free/reduced-lunch percentages are blank for both schools, so economic context cannot be assessed. Harris Brook is about 1.61 times larger and accounts for nearly 62% of elementary enrollment in this ZIP code.
