Summary:
ZIP code 02141 in Cambridge has one middle school, Cambridge Street Upper School, serving grades 6–8 and enrolling 301 students. Because it is the only middle school in the ZIP, there is no local peer comparison; the useful comparisons are with its Cambridge district and Massachusetts. Cambridge is a high-performing district, ranked 71 of 351 statewide, at the 80th percentile with 4 stars.
The school’s 2025–2026 results are above the state in every reported MCAS subject: ELA 49.65% vs. 40.03%, math 44.44% vs. 41.11%, science 50.52% vs. 40.98%, and civics 47.37% vs. 39.77%. It is still below the Cambridge district average in all four areas, with the largest gap in math (−12.85 points) and the smallest in science (−0.51 points). Rank improved from 203 of 484 in 2024–2025 to 139 of 478 in 2025–2026, moving from 3 to 4 stars and reaching the 71st percentile. Gains were large in science (+20.29 points) and civics (+20.63 points), and more modest in math (+7.21) and ELA (+2.47). Eighth grade is the standout: ELA 59.80% (18.10 points above state), math 56.12% (14.45 above state), and science 50.52% (above both district and state). Math remains the clearest weakness, especially 7th grade at 34.12%, which is below both district and state; 6th-grade math is also slightly below state.
Resource metrics are notable: a student-teacher ratio of 8.2 in 2024–2025 and per-pupil spending of $33,606 in 2020–2021, though the spending figure is outdated. Free/reduced-lunch data is blank, so it is unknown and should not be treated as zero. Overall, the school’s story is strong improvement—especially in science and civics—and 8th-grade results above state averages. The main challenge is math in grades 6 and 7. Parents should note that the school is above state but still behind its own high-performing Cambridge district.
