Summary:
Zip code 95446 has two schools in the Guerneville Elementary district: Guerneville Elementary (Charter), serving kindergarten through grade 8, and Guerneville Primary, serving kindergarten only. The Charter school has 171 students, while Primary has 12. Only the Charter has reported test results, so the data cannot show how the schools compare academically. Most importantly, the Charter’s 2025–2026 results were below state proficiency in all three subjects, although slightly above district results.
The Charter stands out as the only school with achievement results, and it was ahead of the district by about 1 point in ELA and science and about level in math. Its all-grades proficiency was 38% in ELA, 21% in math and 31% in science, compared with 37%, 20% and 30% districtwide. State results were higher at 49%, 38% and 36%, respectively; the largest gap was in math, where the Charter trailed by 18 points. Grade 3 ELA was a bright spot: 50% proficiency, 6 points above the state. In contrast, grade 6 ELA was 25%, 23 points below the state, and math trailed the state in every grade with reported results. Because Primary has no test scores listed, these data cannot identify it as either stronger or weaker academically.
The Charter’s proficiency improved in all three subjects from 2024–2025 to 2025–2026: by 1 point in ELA, 2 in math and 13 in science. Science was also the closest subject to the state in both years. SchoolDigger ranked the Charter in the 36th percentile in 2023–2024, 20th in 2024–2025 and 23rd in 2025–2026; its latest rating was 1 star, compared with 2 stars in 2023–2024. For 2024–2025, free/reduced lunch eligible was 81% at the Charter and 75% at Primary; student-teacher ratios were 17 and 12, respectively. These are contextual observations, not explanations for achievement. In 2025–2026, chronic absenteeism was 28% at the Charter, compared with 18% statewide, while Primary reported 17%.
