Its 2025–2026 results are available for English language arts (ELA), mathematics and science. The school’s most important strength is that its all-grades results exceeded California’s in all three subjects, by 31 percentage points in ELA, 29 in mathematics and 22 in science.
Rancho Pico is both the top and bottom school in this ZIP code by default, so that does not show how it compares with nearby schools. Its 2025–2026 results were 80% in ELA, 67% in mathematics and 58% in science, compared with state results of 49%, 38% and 36%, respectively. It also exceeded the William S. Hart Union High district by 10 points in ELA, 16 in mathematics and 7 in science. Chronic absenteeism was another favorable comparison: 8% at the school, versus 13% in the district and 18% statewide.
Results changed by subject from 2024–2025 to 2025–2026: ELA slipped 1 point, mathematics rose 1 point and science fell 3 points. The school’s lead over California narrowed by 2 points in ELA and 7 in science, while the mathematics gap was essentially unchanged. SchoolDigger gives Rancho Pico five stars and ranks it 164th of 2,703 California schools, in the 94th percentile; it ranked 134th of 2,761 schools and in the 95th percentile the prior year. Its 2024–2025 student–teacher ratio was 23.5, and 13% of students were free/reduced lunch eligible that year; these are useful context, not explanations of test results. With only one school listed, the data cannot support meaningful school-to-school comparisons in the ZIP code.
