Summary:
ZIP code 01752, covering Marlborough, Massachusetts, contains three high schools in this data set: two comprehensive public high schools serving grades 9–12 and one charter school serving grades 6–12, which means its enrollment and "all grades" test scores are not perfectly comparable to the other two.
The clear academic standout is Advanced Math and Science Academy Charter School, ranked 33rd of 353 schools statewide in 2025–26 (91st percentile, 5 stars), with a 100.0% graduation rate, a 0.0% dropout rate, and 10th-grade proficiency well above the state in ELA (77.94% vs. 45.48%), math (85.93% vs. 43.73%), and science (74.07% vs. 40.50%). Assabet Valley Vocational High School has a very different profile: it is exceptional in physics at 95.83% proficient vs. the state's 46.58%, and posts a 98.5% graduation rate with a 1.5% dropout rate, yet its 10th-grade ELA, math, and science proficiency are each below state averages. Marlborough High is strongest in biology at 54.29% vs. the state's 37.68%, and its state rank improved from the 23rd percentile in 2023–24 to the 40th percentile in 2025–26, though its physics proficiency is low at 16.47%.
Enrollments are similar — 1,144 at Assabet, 985 at Marlborough, and 970 at AMSA across grades 6–12 — while student-teacher ratios are 10.0, 11.2, and 11.8 respectively. AMSA reports the lowest per-student spending of the three ($16,675 in 2020–21, vs. $20,329 and $20,484), and while that pattern is interesting, older spending figures and the small number of schools mean it should not be read as causal. District ranks differ notably: AMSA's district sits at 57/351 (84th percentile, 4 stars), while Assabet Valley Regional Vocational Technical is at 269/351 and Marlborough at 290/351 — meaning Marlborough High itself is outperforming its broader district picture. Free/reduced-lunch data are blank for all three schools, so economic context cannot be compared here.
