Charter Oak Unified, CA - District Data

Original Research by School Decision on Charter Oak Unified

Charter Oak Unified serves a district spanning parts of Los Angeles County, with enrollment distributed across kindergarten through grade twelve. The district's student body is predominantly Hispanic, with smaller representations of white, Asian, and Black students. The enrollment sits at several thousand across elementary, middle, and high school grades.

The district's academic performance shows persistent challenges across tested subjects. In English language arts, proficiency hovers around the low to mid-range across grade levels, with stronger performance at the sixth-grade level and weaker results in the upper elementary grades. Mathematics performance is notably lower, with proficiency rates substantially below half across all tested grades from third through eighth. Science results are among the weakest, with proficiency rates in the low range at both fifth and eighth grades. These results place Charter Oak Unified below the midpoint in overall proficiency when compared to other Los Angeles County districts. A parent reviewing these numbers may want to speak directly with the district about literacy and numeracy supports, particularly in the elementary and middle grades.

Chronic absenteeism in the district runs at a rate above the median for county districts, which may be worth exploring as a factor in academic outcomes. Per-pupil spending falls in the lower-middle range among county districts.

The district operates a traditional school structure with elementary, middle, and continuation high school options, along with two alternative programs. Charter Oak High serves as the comprehensive high school. Arrow High operates as a continuation school, and the district maintains Oak Knoll Alternative and Bridges Community Day as additional pathways for students whose needs differ from a conventional setting.

A standing feature for families is the District of Choice program, which allows non-resident California families to enroll tuition-free without a release from their home district. Applications cycle annually, though acceptance has reached capacity for students from Azusa, Pomona, and Rowland districts. Additionally, Oak Knoll Virtual Academy offers a tuition-free online and hybrid learning option across all grade levels, including for District of Choice families. This gives households seeking remote or blended instruction a permanent option within the district's structure.

Housing in the district's coverage area, which spans Covina, Glendora, and San Dimas, reflects mid-range Los Angeles County prices. Rental costs account for a substantial share of household income in the region. The area sits within a normal economic environment, with unemployment and mortgage rates at typical levels for the broader economy.
