Summary

Central Union High is a large, traditional public high school serving about 2,000 students in grades 9-12 in El Centro, part of the Central Union High School District, which serves a community with significant economic need.

The school has a distinctive and impressive profile, defined by its exceptional ability to support students through to graduation. It boasts a 98.5% graduation rate, far exceeding the state average, and has dramatically reduced its dropout rate to just 1.3%. Furthermore, students attend school regularly, with a chronic absenteeism rate of 11.3% that is much lower than both the district and state. This success in keeping students engaged and on track happens even as academic proficiency, particularly in mathematics (19.2%), remains a significant challenge, though performance in English Language Arts matches state averages. Compared to other local schools like Calexico High, Central Union achieves stronger graduation and attendance outcomes while spending less per student.

Within its own district, Central Union High consistently outperforms its sister comprehensive high school, Southwest High, in key areas like graduation and attendance. The school shows notable effectiveness with English Language Learners but has seen recent declines in performance for students in special education, an area needing attention. Overall, the school represents a model of efficient resource use and strong student support systems, creating a pathway to graduation even as improving math and science instruction remains a clear opportunity for growth.
