Summary
Adelante High is a small school serving 40 students in grades 10–12 in Riverbank, California, within Riverbank Unified. Its most urgent concern is attendance: 66% of students were chronically absent in 2025–2026, compared with 21% in the district and 18% statewide; among nearby schools reporting a rate, only Robert Elliott Alternative Education Center was higher, at 78%.
English language arts is the school’s strongest tested subject, but results remain below nearby, district and state comparisons. In 2025–2026, 25% of Adelante students were proficient in ELA, versus 34% in the district, 49% statewide and a 45% average for nearby schools. Mathematics is the clearest weakness: proficiency was 0%, compared with 23% in the district, 38% statewide and a 20% nearby-school average. Science proficiency was 9%, versus 22% in the district, 36% statewide and a 23% nearby-school average. Among nearby schools, Adelante ranked third-lowest in ELA, tied for lowest in math and second-lowest in science.
Results have moved in different directions over time: from 2022–2023 to 2025–2026, ELA rose 4 percentage points and science rose 6, while math fell 3 points to 0%. SchoolDigger gives Adelante a 16th-percentile statewide ranking and 1 star for 2025–2026; its percentile has risen from 1 in 2023–2024, but remains low. The student-teacher ratio was 12.6 in 2024–2025, below the nearby-school average of 19. In that same year, 80% of students were free/reduced lunch eligible, compared with a 62% nearby-school average. SchoolDigger’s statewide ranking for English Language Learner Students fell from the 68th percentile in 2017–2018 to the 3rd percentile in 2022–2023, a sharp decline in how well the school served this group by that measure.
