whatever program you're looking at should list the dates they accept applications on their website. most programs i know of are already in the interview process for the january starts, applications were accepted in september.
Check the hospital websites you're interested in EVERY DAY. I applied for new grad programs and my top hospital only had the applications up for one week online, so I had to be persistent in my checking or else I would have missed it.
I check all hospital websites in my area q. day and I check on indeed.com and simplyhired.com for hospitals that I could possibly relocate to. Unfortunately many of us are either having to relocate or drive a long commute to get in a new grad program-at least that is my experience in DFW texas! Good Luck and be persistant!
is kaiser officially open for new grads or are they still just accepting apps for future employment?
I don't know: I'm not a new grad so I wasn't specifically looking for programs--I just happened to come across their new grad posting a few days ago. I'd check with the Kaiser website for the latest info.
