Summary:
Zip code 93450 has one listed school, San Ardo Elementary, serving kindergarten through eighth grade and enrolling 76 students. In 2025–2026, its all-grades proficiency was 18% in English language arts (ELA), 30% in math and 18% in science, below California’s 49%, 38% and 36%, respectively. The most important finding is that results improved in all three subjects from the prior year, but remained below state figures in every subject.
San Ardo Elementary is both the highest- and lowest-performing school in the list because it is the only one, so there is no meaningful comparison among local schools. Within its results, math is the relative strength: it was 8 percentage points below the state, compared with gaps of 18 points in science and 32 in ELA. Fifth-grade results showed a similar pattern: math was 25% versus 37% statewide, while ELA was 25% versus 49% and science 17% versus 35%. SchoolDigger ranks the school at 4,743 of 5,804, in the 18th percentile, with one star. These data cannot show whether another nearby school performs better or worse.
The largest year-over-year gain was in math: San Ardo rose 15 points from 2024–2025 to 2025–2026, while ELA rose 5 points and science 12 points; the school-to-state gaps narrowed in all three subjects. SchoolDigger’s ranking history is mixed: the school moved from the 2nd percentile in 2021–2022 to the 24th in 2023–2024, then to the 18th in 2025–2026. Chronic absenteeism was about 18%, nearly the same as the state rate. The school had a 15.2 student-teacher ratio in 2024–2025, and 95% of students were eligible for free or reduced-price lunch that year; these figures provide context, not an explanation for test results.
