Summary:
ZIP code 91602 has three schools serving kindergarten through grade 12: Walter Reed Middle (grades 6–8), Rio Vista Elementary (K–5), and alternative school Berenece Carlson Home Hospital (K–12). Their 2025–26 results show a mixed area picture: the equal-school average was 2 points above California in ELA and 3 points above in math, but 3 points below in science. The most important finding is that the ZIP code does not offer a uniform academic picture: school results vary substantially, with the widest gap in science.
Walter Reed stands out at the top, with 66% proficient in ELA, 53% in math, and 54% in science—above the state in all three subjects and the highest results among these schools. SchoolDigger places it at the 85th statewide percentile and gives it 4 stars. Berenece Carlson is at the bottom, with 40% in ELA, 18% in math, and 17% in science; its results trail Walter Reed by 26, 35, and 37 percentage points, respectively. Rio Vista falls between them in ELA and science, but its 51% math result is close to Walter Reed; SchoolDigger ranks it at the 62nd statewide percentile, with 3 stars. In grade 8, Walter Reed also led Berenece by 28 points in ELA, 44 in math, and 40 in science.
Recent changes were uneven, so no single trend describes all three schools. From 2024–25 to 2025–26, Rio Vista gained 6 points in math and 2 in ELA, but fell 13 points in science; the three-school science average dropped 4 points while California’s rose 3. Walter Reed’s ELA and math slipped slightly, while its science result rose 3 points. As context, in 2024–25, free/reduced lunch eligible students made up 58% at Walter Reed, 55% at Rio Vista, and 86% at Berenece. Student-teacher ratios were 24.4, 23.2, and 3.9, respectively. The schools differ in type and grade span, and these figures do not explain why results differ.
