Columbia Union

Nestled in the rural fringe setting of the Sonora, California metropolitan area, Columbia Union is an active, traditional public school district dedicated to serving local youth. Located at 22540 Parrotts Ferry Road in Columbia, California, the district operates a single school serving primary and middle school grades from kindergarten through eighth grade. According to National Center for Education Statistics (NCES) data for the 2024–2025 school year, the district educates a close-knit student body of 466 pupils. This balanced community spans 77 kindergarteners through 48 eighth-graders, representing a diverse demographic background—including White, Hispanic, multiracial, American Indian, Black, Asian, and Pacific Islander students—flourishing together in a tailored, small-town educational environment.

To support its academic mission, Columbia Union maintains an exceptionally well-resourced staffing framework focused on individual student success. The district employs a total workforce of approximately 120 full-time equivalent (FTE) staff members, which includes nearly 54 FTE teachers, 16 FTE instructional aides, and over 50 dedicated support personnel. This generous staffing structure fosters a low student-to-teacher ratio, allowing for enhanced classroom support, personalized instruction, and strong operational stability.
