Summary:
ZIP code 95415 has one listed elementary school, Anderson Valley Elementary, serving kindergarten through grade 6 and enrolling 190 students. The latest test results are for 2025–2026. With no other listed elementary schools, families cannot compare local schools against one another; the clearest picture comes from comparing this school with state and district results. The most important finding is that its latest all-grades results were below California’s in English language arts, mathematics, and science, with the largest gap in science.
Anderson Valley Elementary is the only school, so it is both the highest and lowest in this list by default—not a meaningful local ranking. Mathematics is its relative bright spot: 26% of students were proficient, slightly above the Anderson Valley Unified district’s 24%, but below the state’s 38%. The strongest grade-specific result was fourth-grade mathematics, at 44% compared with 42% statewide; the reported advantage was about 1 percentage point. By contrast, third-grade mathematics was 16% versus 47% statewide. Overall, school results were 30% in ELA, 26% in mathematics, and 13% in science, compared with 49%, 38%, and 36% statewide, respectively.
Recent changes were mixed: from 2024–2025 to 2025–2026, all-grades mathematics rose 9 percentage points and ELA rose 3, while science fell 13 points. SchoolDigger’s school percentile improved from the 8th percentile in 2023–2024 to the 23rd in 2025–2026; it gives the district a rank of 655 out of 968, a 32nd-percentile standing, and 2 stars. For context, the school reported a student–teacher ratio of 19 to 1 and 75% of students free/reduced lunch eligible in 2024–2025. These figures describe the school but cannot be used to compare it with other schools in the ZIP code.
