Summary

Central Union High is a public high school serving grades 9–12 in El Centro, California, with 2,006 students. Its 2025–2026 results show a mixed picture: graduation and attendance are strong, while academic proficiency varies by subject. The clearest concern is science: 19% of students were proficient, compared with 36% statewide.

English language arts is a relative strength: 55% of students were proficient, above the state’s 49% and the district’s 53%. That result is between nearby Imperial High at 64% and Southwest High at 53%. Math proficiency was 25%—above the district’s 23% and higher than Southwest, Calexico High and Imperial, but below the state’s 38%. Science was below the district’s 20% and the state’s 36%; it also trailed Southwest and Imperial, though it was above Calexico. Graduation was 97%, compared with 95% in the district and 88% statewide. Chronic absenteeism was 10%, lower than the district’s 16% and the state’s 18%.

Results have shifted over time: from 2022–2023 to 2025–2026, math proficiency rose from 18% to 25%, while ELA fell from 58% to 55% and science from 21% to 19%. SchoolDigger ranks the school 1,143rd of 2,137 California schools, at the 47th percentile and two stars, down from the 66th percentile in 2023–2024. Its student-teacher ratio is 20.9. In 2024–2025, 73% of students were free/reduced lunch eligible, close to Southwest’s 72%. SchoolDigger’s statewide effectiveness ranking for Special Education Students fell to the 16th percentile in 2025–2026, from the 53rd percentile in 2023–2024, compared with the school’s overall 47th percentile.
