Summary
Weston Ranch High is a public high school in Stockton, California, serving grades 9–12 and 1,164 students in Manteca Unified. Its outcomes are mixed: the graduation rate is 94%, above California’s 88%, while chronic absenteeism is 29%, compared with 18% statewide. The most important concern is mathematics proficiency: 12% of students are proficient, 27 percentage points below the state.
English language arts is the school’s clearest relative strength, while mathematics is its biggest academic weakness. In 2025–26, 43% of students were proficient in ELA, above the district’s 35% and the nearby-school average of 34%, though below California’s 49%. Mathematics proficiency was 12%, compared with 23% in the district and 38% statewide; science was 19%, versus 23% and 36%. Even so, Weston Ranch High placed fourth among nine nearby schools with current scores in each of the three subjects, a stronger local position than its state comparisons alone might suggest.
Results have not risen steadily: between 2022–23 and 2025–26, ELA proficiency fell by 2 percentage points, while mathematics and science each rose by 2 points; all three finished below recent highs, and the gap with California widened in every subject. SchoolDigger ranked the school at the 31st percentile with 2 stars in 2025–26, down 16 percentile points from 2023–24. Its 2024–25 student-teacher ratio was 19.4:1, compared with a nearby-school average of 20.9:1; 73% of students were free/reduced lunch eligible that year, versus a nearby average of 77%. SchoolDigger’s statewide ranking for Special Education Students was at the 7th percentile in 2025–26, compared with the school’s overall 31st percentile, indicating a substantially lower relative standing in how the school serves that group. Its ranking for Asian Students was also lower, at the 12th percentile. These figures provide context, not an explanation for student outcomes.
