It may be difficult for her to stay in CA since admission to BSN nursing programs is very competitive instate. Regardless of location she should focus on direct-admit programs which means if you progress satisfactorily in the program you graduate with a nursing degree. Much less desirable are programs where you take pre-nursing courses and then have to apply for the actual nursing major since they enroll many more kids the 1st two years than they have room for in the nursing major, and kids at other schools can also apply to transfer in. Read thru the threads in Nursing Major - College Confidential Forums to find out more about direct-admit schools and nursing admissions in general.
Has she been volunteering or working in medical settings? Some schools don’t care but others factor that into admissions. It will say on the school website. I’ll add that it’s a good idea to get exposure to something before you decide to spent your career doing it.
You should tell her about an alternative approach should she not get into any direct-admit schools or get enough financial aid, which is to get an RN at a community college (an ADN degree) and then go to one of the RN->BSN programs. These community college RN programs can be competitive to get into as well. Look for a good NCLEX pass rate at the CC. I know nurses that have done this. RN->BSN programs tend to much be easier to get into than direct-admit or nursing from pre-nursing BSN programs. See http://www.rn.ca.gov/education/rntobsn.shtml for a list. Many RN->BSN programs are part-time and/or online, but some are campus based. The downside is the college experience with this approach is not the same as the 4-year path but sometimes that’s how life works.
