Summary:
Aberdeen School District 06-1 has one listed high school, Central High School - 01, serving grades 9–12 in Aberdeen, with 1,384 students. The clearest concern in the results is mathematics: Central was 17 percentage points below the state on the 2024–2025 Smarter Balanced assessment, with 27% proficiency compared with 43% statewide.
There is no meaningful top-to-bottom comparison among schools in this list: Central is both the highest- and lowest-scoring by default. Its 2024–2025 Smarter Balanced results were mixed by subject: ELA was 56% proficient, 5 points above the state; science was 46%, 2 points above; and math was 27%, 17 points below. On the 2025–2026 grade 11 ACT, all three subjects were below the state: ELA was 41% versus 48% (7 points lower), math was 27% versus 34% (7 points lower), and science was 40% versus 45% (5 points lower). These results make math the most consistent state-relative weakness, while ELA and science were above the state on Smarter Balanced.
SchoolDigger’s rankings for Central moved from 108th of 141 schools (23rd percentile) in 2023–2024 to 97th of 166 (42nd percentile) in 2024–2025, then to 99th of 130 (24th percentile) in 2025–2026; the latest percentile is 18 points below the prior year. This ranking history does not show a clear test-score trend, and the supplied data cannot support school-to-school comparisons or a like-for-like test-score trend. Central’s 2025–2026 graduation rate was 86%, 2 points below the state and about 1 point above the district. In 2024–2025, 34% of students were free/reduced lunch eligible; the student-teacher ratio was 17.2 and per-student spending was $10,660.
