Dayton High School is the stronger documented option for families comparing academic outcomes. In 2024–25, it ranked 127th out of 438 Washington schools, placing it in the 71st percentile and earning four stars—an improvement from the low-to-mid 50th percentile in the prior two years. Its 75% graduation rate was 11 percentage points higher than the district rate, though it remained below the statewide rate of 82.6%. The school also outperformed district and state averages in English language arts, math, and science. English was especially strong, with 76.47% of students proficient, while math was comparatively weaker at 51.52%. The school’s small enrollment and 8.9-to-1 student-teacher ratio may support a close-knit environment.

The main issues for families to investigate at Dayton High School are the gap between its graduation rate and the state average, its historically reported 26.3% dropout rate from 2021–22, and the need for continued attention to mathematics. Current 2025–26 school assessment results are suppressed, so they should not be interpreted as zero or poor performance. The alternative program has a higher reported free/reduced-price lunch rate—53.85% versus 42.05%—but no school-level graduation, testing, ranking, or dropout data. Because it is very small and serves grades 6–12, parents should ask about its specific supports, curriculum, credit recovery, graduation planning, and recent student outcomes rather than compare it directly with the traditional high school.
