About Mt. Diablo Unified
Description provided by the district or community — not part of the NCES dataset.
Nestled at the base of Mt. Diablo in the suburban East San Francisco Bay Area, the Mt. Diablo Unified School District, can be characterized as a representative California microcosm. Mt. Diablo is one of the largest school districts in the state of California, with over 56 school sites and programs. The district's statistics for ethnic/racial diversity, average class size, test scores, numbers of Limited English Proficient (LEP) students and the primary languages they represent, mirror those for the State of California as a whole.
