Summary:
Roxbury Preparatory Charter (District) in Massachusetts is a single-school district serving grades 5–12, with one high school — Roxbury Preparatory Charter School, located at 71 Proctor Street, Roxbury, MA 02119, and enrolling 1,126 students. Because the district contains only that one school, all district-level test scores, graduation rates and dropout rates are identical to the school's values, so there are no within-district comparisons to make.
Mathematics is the relative bright spot. Overall math proficiency is 33.66% of students, the strongest of the three "All Grades" core subjects, and it improved from 31.64% the prior year, narrowing the gap with the state from -9.10 to -7.45 points. Eighth grade math (42.69%) is the only listed 2025–2026 assessment above the state rate of 41.67%, and 6th grade math (39.53%) is just 3.06 points below the state. English Language Arts, however, is below the state at every grade, from 30.06% in 8th grade to 20.45% in 10th grade, where the gap is -25.03 points. Science overall is 23.35% versus the state's 40.98%, and 8th grade Civics is the lowest figure in the data at 13.77% versus 39.77% — a 26-point gap that also widened from the prior year. Tenth grade math is similarly weak at 17.56% versus 43.73%.
Other figures give context. The graduation rate is 85.6% and the dropout rate is 12.6%, roughly one in eight students, though the data set provides no state comparator for these. The student-teacher ratio is 25.8:1, and per-student spending was $19,636 in 2020–2021, a different year from the achievement data. The district summary ranks the school 298 of 351 with 1 star and 15th percentile, while rank history shows movement from 0 stars / 9th percentile in 2023–2024 to 1 star / 22nd percentile in 2024–2025, holding 1 star / 20th percentile in 2025–2026. Free/reduced-lunch data is not reported, so it is unknown rather than zero.
