Summary
Chino High is a public school in Chino, California, serving grades 9–12, with 2,077 students in Chino Valley Unified. Its graduation rate is strong at 96% in 2025–26, above the state’s 88%, while chronic absenteeism is a concern at 24%, compared with 18% statewide and 14% districtwide. The most important academic concern is mathematics: only 25% of students were proficient, well below the state’s 38% and the district’s 51%.
English is a relative strength: 64% were proficient, 14 points above the state, about level with the district, and 2 points above the nearby-school average; Chino High ranked fifth of eight nearby schools with reported results. Math ranked seventh of eight and was 5 points below the nearby average of 30%. Science proficiency was 31%, below the state’s 36%, the district’s 45%, and the nearby average of 34%; the school ranked fifth of eight nearby schools. The reported 12th-grade science result was 0%, versus 33% statewide and 13% districtwide, a notable result to clarify with the school.
Results have improved since 2022–23: ELA rose 8 points, math 9, and science 10, though math and science still trail the state. SchoolDigger gives the school 3 stars and ranks it in the 59th statewide percentile for 2025–26, up from the 53rd percentile in 2023–24; among eight nearby schools with same-year percentiles, it ranks sixth. The student-teacher ratio was 21.8 in 2024–25. The school reported 77% free/reduced lunch eligible in 2024–25; because California is identified as a statewide-free-meals state, read this as the school’s reported measure, not a comparison of access to meals. One striking SchoolDigger group-specific result: its relative statewide ranking for how well it serves African American students rose to the 95th percentile in 2025–26, from the 20th percentile the prior year.
