CVHS experienced several population shifts as the district opened the new schools of Aliso Niguel and Tesoro with the building boom in southern Orange County. Student attendance shifted between these schools as district boundaries were re-drawn with each new school addition. The 2006-2007 school year was the last year that San Juan Capistrano freshmen students enrolled at CVHS. In the 2007-2008 school year, most SJC freshmen attended the district's new San Juan Hills High School. A few San Juan Capistrano students who live close to the Mission Viejo/San Juan city borders continue to attend CVHS.
