Summary
Edison High is a public high school in Stockton, California, serving grades 9–12 in Stockton Unified and enrolling 2,355 students. Its outcomes are mixed: 97% of students graduated and 2% dropped out in 2025–2026, but 38% were chronically absent, compared with 31% districtwide and 18% statewide. The most important concern is low academic proficiency, especially in mathematics, where just 9% of students were proficient.
ELA is Edison High’s strongest subject relative to its district, but its scores trail the state and same-district peers in all three subjects. ELA proficiency was 33%, 3 percentage points above the district and 17 below the state; it ranked fourth among seven same-district high schools and was 12 points below the other six schools’ average. Mathematics proficiency was 9%, 9 points below the district and 30 below the state, while science was 16%, 2 points below the district and 20 below the state. The school ranked fifth of seven in both subjects. Its graduation rate was a bright spot: 4 points above the district and 9 above the state. Chronic absenteeism, however, was the second-highest among the seven same-district schools with data; only Stockton High was higher.
Since 2022–2023, mathematics proficiency has risen 2 points and science 4 points, while ELA has fallen 3 points; the gap with the state widened in all three subjects. Edison High is ranked 1,609th of 2,137 California schools by SchoolDigger, at the 25th percentile with one star. Its student–teacher ratio is 23.7, above the 19.6 average for same-district peers. In 2024–2025, 80% of students were free/reduced lunch eligible, close to the peer average of 80%. SchoolDigger’s statewide ranking for Asian students was at the 1st percentile in 2025–2026, compared with the school’s overall 25th percentile; its ranking for African American students fell from the 34th percentile in 2023–2024 to the 12th percentile in 2025–2026.
