Summary:
ZIP code 02124 covers 10 schools serving 6,728 students in Boston's Mattapan and Dorchester neighborhoods, spanning PK–3 through high school, with five elementary schools, two high schools, three alternative schools, and no standalone middle schools (middle grades sit inside PK–8 and 6–8 campuses). Enrollment is very uneven: Brooke Charter School alone enrolls 2,216 students, about 33% of all students in the ZIP, while Lee Academy is the smallest at 195. Seven schools belong to Boston Public Schools; three are charter districts: Brooke Charter School (District), UP Academy Charter School of Dorchester (District), and Codman Academy Charter Public (District).
Academically, the gap inside this ZIP is extreme. Brooke Charter School is the only school above the state in all three core subjects (ELA 62.61% vs. state 40.03%, math 73.87% vs. 41.11%, science 66.40% vs. 40.98%). Holmes Elementary School is the strongest Boston district elementary here (ELA 27.21%, math 20.59%, science 23.33%) but still well below state. UP Academy Charter School of Dorchester improved markedly in math (12.34% to 20.84%) and science (13.22% to 21.14%), and its 8th-grade civics score of 43.40% beats the state's 39.77%. At the other end, TechBoston Academy posts 10.96% ELA, 7.05% math, and 6.67% science, and Boston International High School & Newcomers Academy reports 10th-grade ELA 3.26%, math 3.37%, and science 0%.
Completion results tell a different story than test scores. TechBoston graduates 88.6% with a 2.9% dropout rate, and Codman Academy Charter Public School graduates 88.9% with 5.6% dropout, both better than the Boston district's 81.3% and 8.8%. Boston International has the weakest outcomes (57.6% graduation, 30.4% dropout). Per-student spending (2020–21) ranges from about $16,769 to $31,540 but does not track proficiency simply, and free/reduced-lunch data are blank for every school, so poverty comparisons aren't possible here.
