Summary:
ZIP code 94523 has six K–5 elementary schools, all part of Mt. Diablo Unified, with enrollments ranging from 323 to 721 students. Across the six schools, the 2025–2026 average was 53% in ELA, 50% in math and 42% in science, each above the state result. The most important finding is that results differ sharply by school: the gap between the highest and lowest school is 51 percentage points in ELA, 53 in math and 55 in science.
Sequoia Elementary leads in all three all-grades subjects, with 74% in ELA, 74% in math and 66% in science; it is the only school above 70% in ELA or math. It leads the next-highest school by 8 points in ELA, 17 in math and 6 in science. At the other end, Fair Oaks Elementary is lowest in all three, with 22% in ELA, 21% in math and 12% in science. Other schools have specific strengths: Pleasant Hill Elementary leads third-grade math at 69%, while Strandwood Elementary is next behind Sequoia in ELA and science.
Across the two available years, the six-school average rose by about 1 point in ELA, 2 in math and 4 in science, and the group’s advantage over the state widened in each subject. That pattern was not universal: Valhalla Elementary declined in all three subjects, while Pleasant Hill declined in ELA and science. SchoolDigger ranks Sequoia in the 92nd percentile with five stars and Fair Oaks in the 11th percentile with one star. The 2024–2025 free/reduced lunch eligible measure ranged from 20% at Valhalla to 86% at Fair Oaks; these figures provide context, not an explanation for results. In 2025–2026, chronic absenteeism was 1% at Sequoia and 31% at Fair Oaks, compared with 18% statewide; student–teacher ratios do not follow the same score ordering, at 28.2 for Sequoia and 23.0 for Fair Oaks.
