Hi there! I'm not sure if CNA is a requirement for all nursing programs in Sol Cal, but up here in No. Cal, it is not. Our ADN programs do not require it, and neither does the program I'm in (BSN at Chico State). What I do know is the I wish I had a CNA before starting the program. I might have been less FREAKED over the first patient care day. If you have the time, it's a good idea!
