Summary

Dunham Charter is a K–6 school in Petaluma, California, with 166 students. Its 2025–2026 proficiency rates were above California’s in English language arts (ELA), math and science. The most important finding is that the school remains ahead of the state in all three subjects, but results fell in every subject from the previous year.

ELA is Dunham’s strongest comparison with nearby schools, while science is its weakest. ELA proficiency was 57%, compared with 49% statewide and a nearby-school average of 45%; Dunham was slightly above the Dunham Elementary district’s 57%. Math was 50%, above the state’s 38% and nearby average of 40%, but below the district’s 51%. Science was 38%, just above the state’s 36% and equal to the district, but below the nearby average of 42%. Grade-level results show a clear difference, too: grade 4 and 5 math were both 57%, above their state rates of 42% and 37%, while grade 3 math was 38%, below the state’s 47%.

The latest declines followed stronger 2024–2025 results: ELA fell 10 percentage points, math 12 and science 6. Compared with 2022–2023, however, each subject was modestly higher in 2025–2026. SchoolDigger places Dunham at the 70th percentile with 3 stars, down from the 82nd percentile the year before; nearby Liberty Elementary and Gravenstein Elementary rank higher. SchoolDigger’s subgroup ranking for “White Students” was at the 36th percentile, compared with 70th overall, and fell from the 58th percentile in 2023–2024. Its “Male Students” ranking also dropped, from the 84th percentile in 2023–2024 to the 69th in 2025–2026. For context, Dunham’s 2024–2025 student-teacher ratio was 21.5:1, and 27% of students were free/reduced lunch eligible that year.
