Brooke Charter School

Brooke Charter School in Mattapan, MA is a K–12 charter school serving 2,216 students at 200 American Legion Highway that operates as its own single-school Brooke Charter School (District), making it by far the largest school in its comparison group — roughly 1.9 times the size of Match Charter Public School and more than 2.5 times Prospect Hill Academy Charter School — and the only school in the group that combines a full K–12 grade span with enrollment in the thousands.

Academically, Brooke stands out sharply. In 2025–26 MCAS results across all grades, the school scored 62.61% in English Language Arts, 73.87% in math, and 66.40% in science, compared with state averages of 40.03%, 41.11%, and 40.98%. Every one of the nine nearby comparison schools scored at or below the state average in every subject reported. Against the other charter peers, Brooke leads by margins of 31 to 48 percentage points; against its closest geographic neighbor, Codman Academy Charter Public School, the gap is roughly five times in ELA and eight times in math. Every grade-level score in both ELA and math exceeds the matching state figure, and math has risen in each of the last three years, gaining 13.2 points since 2022–23.

Brooke also reports a 90.5% graduation rate — second-highest in the group — while spending $21,044 per student, the lowest of any school with spending data, and with a higher student–teacher ratio (12.4) than other conventional schools listed. Two recent caution flags: the graduation rate fell 4.2 points from 2023–24, the dropout rate rose to 5.7%, and ELA slipped 2.8 points. Eighth-grade science and Civics lag the school's otherwise uniform strength. Free/reduced-lunch data is unavailable for Brooke and its peers, so poverty cannot be statistically controlled; read these comparisons as descriptive, not causal.
