Summary:
ZIP code 20001 has four high schools—Dunbar High School, Benjamin Banneker High School, Garnet-Patterson STAY High School, and Girls Global Academy PCS—and all serve grades 9–12. Their latest reported proficiency results vary widely, so a ZIP-code-wide average does not capture the differences families will see among schools. The clearest standout is Banneker, which led the group in both ELA and mathematics in 2025–2026.
Banneker’s 2025–2026 proficiency was 86% in ELA and 64% in mathematics, compared with state results of 40% and 28%. At the other end, Garnet-Patterson had the lowest ELA result at 5%, while Dunbar was at 11%; Girls Global had the lowest reported mathematics result at 1%, and Dunbar was at 2%. Graduation results add important context: in 2024–2025, Dunbar’s rate was 82%, above the state’s 79%, while Garnet-Patterson’s was 11%, 68 points below the state. Girls Global’s graduation rate was 78%, just 1 point below the state.
Recent ELA results declined at all four schools even as the state result rose: Banneker went from 92% to 86%, Dunbar from 13% to 11%, Garnet-Patterson from 14% to 5%, and Girls Global from 26% to 20%, while the state moved from 38% to 40%. SchoolDigger rankings likewise show contrasting paths: Banneker improved from 3rd of 34 schools in 2023–2024 to 2nd of 37 in 2025–2026, while Dunbar moved from 30th to 37th and Girls Global from 17th to 28th. As context, 2024–2025 direct certification for free meals was 21% at Banneker, 63% at Dunbar, and 62% at Girls Global; Garnet-Patterson’s 55% figure is for 2023–2024, so it is not a same-year comparison.
