For each of the CSUs you should find out how many students intend to major in nursing vs how many actually are admitted into the program (I’m sure you know this of course). I think SFSU is heavily impacted and not that many are admitted. Plus the cost of living in SF is astronomical. And it’s a commuter school, if that matters to her. From her CSU options I personally would choose Chico for a traditional college experience and solid nursing program (depending on the admit rate of course). Can’t comment on her OOS options. And I don’t think the gap year experience will make much of a difference. The CA direct admit programs have miniscule acceptance rates and no matter how qualified your D is, so are most of the other applicants.
Good luck to her! I hope you update us on her decision. Nursing is a second career for me and I’m so happy I made the switch! Hopefully your D will love it too.
