Summary:
The Bridge Boston Charter School (District) is a single-school district in Roxbury, Massachusetts, containing one elementary school — Bridge Boston Charter School — which serves grades PK through 8 to 329 students at 435 Warren St. The school reports a 10.7-to-1 student-teacher ratio and per-student spending of $28,647 (2020–2021); free/reduced-lunch information was not available in the data, so that context is unknown. Because the district has only this one school, there are no in-district peer schools to compare against — the meaningful comparison is with the state.
The clearest good news is momentum. The school's rank moved from the 24th percentile in 2023–2024 to the 39th percentile in 2025–2026, rising from 1 star to 2 stars. Mathematics is a genuine strength: All Grades math proficiency rose from 34.76% in 2024–2025 to 43.15% in 2025–2026, moving from below the state (41.11%) to above it. Grade-level results are even more striking — 8th grade math was 69.23% proficient versus the state's 41.67%, and 5th grade math was 50.00% versus 39.50%. ELA edged up slightly, from 33.16% to 34.01%, but remains below the state's 40.03%.
Science is the biggest concern. All Grades science was 14.52%, down from 17.86% the prior year and far below the state's 40.98%, with 5th grade at 16.67% and 8th grade at 11.54%. Eighth grade civics also fell sharply, from 25.00% to 7.69%, against a state figure of 39.77% — a large swing that should be read cautiously because grade-level cohorts change. Fourth grade was weak in both ELA (24.39% vs. 37.43% state) and math (31.71% vs. 43.20% state), the largest gaps among tested grades. Overall, this is a school improving in the rankings and performing well in math in some grades, but with serious, persistent weaknesses in science, civics, and 4th grade.
