The Contra Costa Community College District (CCCCD) operates three colleges: Contra Costa College, Diablo Valley College, and Los Medanos College. As open-access institutions, these colleges do not have a competitive acceptance rate. They admit all applicants who meet the basic eligibility requirements, such as possessing a high school diploma or equivalent, or being at least 18 years old.
The district focuses on providing accessible education, with enrollment open to both local and international students. While specific enrollment statistics vary yearly, the absence of selective admissions ensures broad accessibility to higher education and workforce training programs.
