Belmont High School was once the largest school in California, due to the density of the Westlake district, which it served. It was also considered the largest school in the United States, with 6,342 students. What was formerly the attendance area for Belmont High School has now become the Belmont Zone of Choice, where students have the option of attending one of nineteen small learning communities or pilot schools located on four different campuses within the zone: Belmont High School, Miguel Contreras Learning Complex, Edward Roybal Learning Center, and Ramon C. Cortinez School of Visual and Performing Arts.
