Summary:
ZIP code 01564 covers Sterling, Massachusetts, and contains exactly one middle school: Chocksett Middle School, a grades 5–8 school with 264 students in the Wachusett district.
Chocksett Middle School is a strong school by the numbers. It earned a 4-star rating in each of the last three reported years, ranking 119 out of 478 schools (75th percentile) in 2025–2026, after 85th percentile in 2024–2025 and 83rd in 2023–2024. Its Wachusett district ranks 97 out of 351 (72nd percentile), also with 4 stars. The student-teacher ratio is 11.4, and per-student spending was $16,037 in 2020–2021. Free/reduced-lunch information is not reported, so family-income context is unavailable.
English language arts is the school's clearest strength. In 2025–2026, all-grade ELA proficiency was 58.63%, above the district's 49.4% and the state's 40.03%. Grade 7 ELA reached 70%, far above both the district and state, and grade 8 ELA was 63.93%. ELA was also the only all-grade subject that improved year over year, up 2.82 points. Mathematics is the main concern: all-grade math fell from 58.59% to 44.76%, a 13.83-point drop, and grade 8 math was just 29.51% — well below the district's 53.14% and the state's 41.67%. Science declined 6.73 points to 50.41% and civics dipped to 54.10%; both remain above the state but now trail the district. Parents should note that in 2024–2025 the school beat the district in every reported subject, while in 2025–2026 it did so only in ELA.
