Summary:
Schools in zip code 95823 include 17 schools—nine elementary, two middle, four high and two alternative schools—serving students from elementary grades through high school across two districts. Results vary widely from school to school, and the area’s average proficiency is below the state result in every subject: about 28% in ELA versus 49% statewide, 21% in math versus 38%, and 18% in science versus 36%. The most important takeaway is that the area-wide averages are below state levels in all three subjects.
Las Flores High leads the all-grades results in all three subjects, at 51% in ELA, 47% in math and 48% in science—about 1, 9 and 12 percentage points above state results. Among elementary schools, Union House Elementary leads in ELA and math, with 41% and 32%; Barbara Comstock Morse Elementary leads in science at 36%, and its fourth-grade ELA result of 59% is 13 points above the state. At the lower end, Rio Cazadero High has the lowest ELA and science results (8% and 0%), while Capital City Independent Study has the lowest math result (4%), 35 points below the state. Las Flores is an alternative school, so its all-grades lead is not a like-for-like comparison with conventional schools.
From 2024–25 to 2025–26, the 17-school average edged down in ELA, while math rose 2 percentage points and science rose 4; individual schools also moved in different directions. SchoolDigger’s rankings show gains from 2023–24 to 2025–26 at William Daylor High (up 16 percentile points), John Reith Elementary (up 9) and Union House (up 8), while Luther Burbank High fell 11. Among the conventional high schools, Valley High leads Burbank in all three subjects by 15 points in ELA, 13 in math and 9 in science, despite similar student–teacher ratios (19.6 and 18.6). Their 2024–25 free/reduced lunch eligible shares were 79% at Valley and 74% at Burbank; these figures provide context, not an explanation of results.
