Clayton Valley Charter High School, opened in the summer of 2012, continuing the long and proud tradition of its predecessor, Clayton Valley High School. Clayton Valley currently serves more than 1900 students in the cities of Concord and Clayton. Part of the Mt. Diablo Unified School District, Clayton Valley is fed by Diablo View Middle School in Clayton and Pine Hollow Middle School in Concord, and by Ayers, Highlands, Silverwood, and Mt. Diablo Elementary Schools. Clayton Valley opened its doors to students in 1958 under the leadership of inaugural principal Dan Della. A copy of the original student handbook from the 1958 school year can be found here. In 2011, a petition was submitted pursuant to California law to convert the school into a teacher conversion charter high school. After a series of steps, on January 11, 2012, the Contra Costa County Board of Education voted unanimously to approve the charter. Clayton Valley Charter High School is in the process of transitioning to the new school and will officially open its doors on July 1, 2012. Classes will begin for all incoming students later this summer. The mission of CVCHS is “to unite our stakeholders, including students, teachers and staff, parents, and community members, in a common goal to diligently prepare all students for success in the 21st Century. We believe in instilling timeless principles and fostering a culture of excellence with RIGOR, RELEVANCE, and RELATIONSHIPS”.
