I have researched this same issue several times as I am in the same type of situation. I did find two schools, one in N. Carolina and one in California, that allowed a part-time option to attend their CRNA programs. I have interviewed for two other programs, and also had to decline a few interviews, and found that there was NO WAY to work full time while attending CRNA school. In fact, it is almost impossible to work at all. I worked full time while attending both LPN and RN programs, in addition to completing my BSN, so I am not one to get much sleep or free time. But everyone I have spoken with pretty much stated in no uncertain terms that I would not be able to do that this time.
There are financial programs available, and most likely grants for agreeing to work for a certain # of years in an underserved area of population. You can access this information at:
