Schools and Programs

Elementary schools

Clayton Valley High School operated as an MDUSD school from 1958 to 2012. In 2012 it was converted to a charter school and is no longer part of the MDUSD.
Pacifica High School operated from 1955 until 1976 when it was closed. The campus was then re-opened as Riverview Middle School.
Pleasant Hill High School operated from 1953 until 1980 when it was closed. The campus later re-opened as Pleasant Hill Middle School.

Alternative schools

The earliest schools in the area were grammar schools, each independently founded after the Civil War. The first school in Concord, for example, was a two-story building constructed in 1870 at the corner of Grant and Bonifacio streets; this was replaced by an even larger school on Willow Pass Road in 1892.
MDUSD was formed in 1948 from the Mount Diablo Union High School District and the local grammar schools.
