We just moved out of Clairemont 92111 (Fox Run) back in early April. I would say that the majority of people we knew did send their kids to Holmes Elementary (the local elementary for that part of Clairemont). We knew a few who sent their kids to a charter school or private/parochial school as well.
For middle school and HS, some seemed to send their kids to either Standley MS/UC High School. There were also several kids who went to Cathedral Catholic. I know of only one girl who attended Clairemont HS (and even that was strange because we were technically in the Madison HS district. However, Clairemont is probably about the same distance or even closer).
