Summary:
Zip code 02122 in Dorchester (Boston, MA) has only one high school in this data set: Community Academy of Science and Health, a grades 9–12 school with 398 students, so there are no other local high schools to compare it against directly.
Because it is the only high school here, the useful comparisons are with the wider Boston district and Massachusetts state averages — and in those comparisons the school trails consistently. In 2025-2026 it ranked 322 of 353 Massachusetts high schools, the 9th percentile with 0 stars, after also earning 0 stars in 2023-2024 (333 of 348, 4th percentile) and 2024-2025 (322 of 349, 8th percentile). MCAS Next Generation proficiency in 2025-2026 was 8.33% in 10th-grade English Language Arts, 9.09% in Mathematics, 7.41% in Science, and 19.51% in Biology End of Course, all below district and state averages; the prior year showed the same pattern. Reported 10th-grade proficiency also fell from 2024-2025 to 2025-2026 in ELA, Math, and Science, though these are different cohorts and not a measure of individual student growth.
For 2024-2025, the graduation rate was 71.9% versus 81.3% for the district, and the dropout rate was 9.4% versus 8.8%. The school reports $29,724 per student in 2020-2021 spending and a 12.6 student-teacher ratio, but this data set offers no district or state figures for those measures, so they cannot be judged high or low from this file alone. The free/reduced-lunch percentage is blank and should be treated as unknown, not as zero or as a sign of low need.
