Summary
Gustine High is a public school serving grades 9–12 and 531 students in Gustine, California. Its 2025–26 results show a clear split: English language arts (ELA) is stronger than the state and district, and science is stronger than the district, but mathematics lags. The most important academic concern is math: 15% of students met proficiency, 23 percentage points below the state and 4 points below Gustine Unified.
ELA and science are relative strengths compared with nearby traditional high schools. Gustine’s ELA proficiency was 54%, above the state’s 49% and district’s 31%; it ranked second among nearby schools, behind Patterson High at 60%. Science proficiency was 28%—8 points below the state, but 2 points above the district—and the highest among nearby schools, including Delhi High, Patterson, Hilmar High and Orestimba High. Math was above only Hilmar’s 13% among those four schools. So, despite the ELA and science strengths, the math gap remains pronounced.
Proficiency has improved since 2022–23: ELA rose 8 percentage points, math 8 points and science 16 points, though math remains well below the state. SchoolDigger gives Gustine a 46th-percentile ranking and 2 stars for 2025–26; among nearby schools with rankings, only Patterson ranks higher. The school has a 19.5:1 student-teacher ratio. In 2024–25, 80% of students were free/reduced lunch eligible, the second-highest share among the five nearby traditional high schools. Other outcomes are mixed: the graduation rate was 99% in 2025–26, while chronic absenteeism was 29%, compared with 18% statewide. SchoolDigger’s English Language Learner effectiveness percentile fell from 72 in 2022–23 to 9 in 2023–24, while the school’s overall percentile was 35 and 37 in those years. For Special Education Students, its effectiveness percentile rose from 11 in 2023–24 to 43 in 2024–25, compared with overall percentiles of 37 and 42, respectively.
