Summary:
Black Oak Mine Unified includes six schools—three elementary schools, two high schools and one alternative school—serving grades from kindergarten through grade 12. In 2025–26, the four schools with reported all-grades results averaged 39% in ELA, 34% in math and 28% in science, compared with state results of 49%, 38% and 36%. State-suppressed test results are unavailable for Otter Creek Elementary and Divide High, and the schools’ different grade spans limit direct comparisons. The clearest academic standout is Northside Elementary, which led the four reporting schools in all three subjects and scored above the state in math and science.
Results vary substantially by school: Northside scored 48% in ELA, 51% in math and 43% in science, while Georgetown Elementary had the lowest reported ELA and science results, at 33% and 13%. American River Charter had the lowest math result, 22%. Its results are mixed rather than uniformly weak: science was 35%, just 1 point below the state, and its graduation rate was 96% versus 88% statewide; chronic absenteeism was 2% versus 18% statewide.
Across the four reporting schools, average ELA fell 6 points from 2024–25 to 2025–26, math rose 2 points and science fell 12 points. Georgetown’s science result dropped 38 points, even as its math rose 4. SchoolDigger’s rankings also declined from 2023–24 to 2025–26 at Golden Sierra Junior Senior High (67th to 51st percentile) and Northside (75th to 66th); these are ranking changes, not test-score changes. As context, the 2024–25 free/reduced lunch eligible measure ranged from 29% at Northside to 78% at Divide, but it does not by itself explain school results.
