The Charter Oak Unified School District


The Charter Oak Unified School District Office is located in Covina and also serves students in the surrounding communities of Glendora and San Dimas.

The District unites the three cities and extends from Grand Avenue on the west, to Valley Center on the east, and from a northern boundary near the 210 Freeway to Covina Hills Road on the south. The first Charter Oak School opened on September 9, 1894 with 24 students.

From that early start in a tent, the District has grown into an award-winning unified district of California recognized for its distinguished schools and serving nearly 7,000 students on eight campuses.


Charter Oak is a community where people are proud to live. Charter Oak joins the heritage of San Dimas, Glendora and Covina to form its own identity. It is a great place for families to live and for children to go to school.

The six square miles of Charter Oak still retain much of the green, shady, small-town atmosphere of caring people.

The Charter Oak Unified School District offers a full range of educational opportunities for students. It has one of the most noted gifted programs in the area for students in grades 3-12. Graduates of our renowned gifted programs are accepted to many prestigious colleges and universities around the world, as well as receiving advanced university standing upon enrollment.


A variety of extra and co-curricular activities are offered at the middle and high school level. We are proud to offer many fine arts programs and championship fall, winter and spring sports programs.

One of the key factors in maintaining the District’s high standards is the help and support of parents. Each school has an active parent-faculty organization. The Charter Oak Unified School District believes in empowering students to be lifelong learners.
