DVC is one of three public community colleges in the Contra Costa Community College District (along with Contra Costa College and Los Medanos College). It opened in 1949.

History

Diablo Valley College was founded in 1949 as East Contra Costa Junior College. The college enrolls over 22,000 students on two sites.

Grade-fixing scandal

In 2007, a six-year grade fixing scheme came to light with allegations that over 70 students used sex or cash as payment to student employees in the admissions and records office in exchange for over 400 grade changes. Many of these students had transferred to universities and in some cases may have already graduated. By November 2007, 49 students had been charged with misdemeanors or felonies over the incident, and at least one had accepted a no contest plea. A spokesperson for the Accrediting Commission for Community and Junior Colleges said that although the scandal was a negative factor it would be unlikely to lead to the school's loss of accreditation.

Its value is orientation rather than verdict, with Diablo, Valley and College providing the first useful test.

The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
