Summary

Charlestown High School is a Boston Public Schools school at 240 Medford Street in Charlestown, MA, serving grades 7–12 with 754 students. It ranks among the lowest-performing schools in Massachusetts, placing 330 of 353 (7th percentile, 0 stars) in 2025–2026 — below its own district, Boston (299 of 351) — and it has stayed in the bottom decile every year on record.

Academic results are far below district and state averages. On the 2025–2026 MCAS, all-grade ELA proficiency is 3.45%, math 13.33%, and science 10.34%, with 10th-grade science at just 5.56%. The school is improving from a very low base: ELA rose from 0% to 3.45% and math from 3.57% to 13.33% over three years. Eighth-grade math (27.59%) is a relative bright spot, close to Boston's 30.20%, though 7th-grade ELA and math are both 0%. Graduation climbed from 51.2% in 2020–2021 to 74.5% in 2024–2025, and dropout fell from 20.1% to 10.8%, but both still trail Boston. For comparison, nearby East Boston High School graduates 94.6% with a 1.8% dropout rate, and Somerville High graduates 89.8%.

Results vary by student group. English Language Learner students rank at the 30th percentile — well above the school's overall 7th — after reaching the 60th–67th percentile in earlier years, and special education students rose to the 32nd percentile in 2025–2026. Hispanic students (3rd percentile) and low-income students (5th percentile) have the lowest rankings. Resources are comparatively strong: $28,709 per student and a student-teacher ratio of 8.0, better than East Boston High School ($26,645 and 11.5). Other nearby alternatives with stronger outcomes include Excel Academy Charter School, Community Charter School of Cambridge, and Somerville High.
