Summary
Valencia High is a 2,411-student school serving grades 9–12 in Placentia, in the Placentia-Yorba Linda Unified district. Its 2025–2026 graduation rate was 98%, higher than the district’s 97% and California’s 88%, while chronic absenteeism reached 20%, above the district’s 14% and state’s 18%. The most important academic takeaway is that Valencia scores above state rates in all three subjects but trails its district and nearby traditional high schools in math and science.
ELA is Valencia’s strongest result against the state: 67% met proficiency, 18 points above the state, and equal to the district. Still, Valencia ranked fourth of seven nearby traditional high schools in ELA, with its result essentially matching the other six schools’ 67% average. In math, 43% met proficiency—5 points above the state but 14 points below the district—and Valencia ranked fifth of seven, 3 points below the peers’ average. Science proficiency was 44%, 8 points above the state but 8 below the district; Valencia also ranked fifth of seven, 4 points below the peers’ average. In short, its statewide advantage does not translate into a local advantage, especially in math.
Results have fallen since 2022–2023: ELA went from 76% to 67%, math from 46% to 43%, and science from 51% to 44%, while the state improved in all three subjects. SchoolDigger ranks Valencia 464th of 2,137 California schools, at the 78th percentile with four stars; its percentile has dropped 12 points from its 2022–2023 high. The 2024–2025 student-teacher ratio was 21.9, and 67% of students were reported as free/reduced lunch eligible. SchoolDigger’s group rankings also differ notably: Valencia ranked at the 98th percentile for how well it serves Asian students, versus the 78th-percentile overall ranking, while its ranking for serving Military Connected Students was at the 47th percentile.
