In Tucson, you have 2 choices (I don't think there are others:
Pima Community College or the University of Arizona.
I graduated from the University of Arizona in 1993. At that time, it was one of the top 5 nursing programs
in the country. Not sure how it is ranked now.
Pima gives you an ADN. The U of A a BSN. I highly recommend both (of course, this is my knowledge of several years ago). I don't know the waiting time to get into either program. Years ago, it was very long.
Almost all the community colleges in AZ have nursing programs. North of Tucson there is one in Casa Grande. Cochise Community (south of Tucson) had one years ago, but I am not sure now.
In Phoenix, WAY back when, I was in Phoenix College Nursing Program. It was the program that, after I got in and then had to drop out (for personal reasons..........TWICE!!!!!) that really convinced my that I wanted to persue this career!
Are you in a nursing program already? If you are and are looking to transfer to a program in AZ, I would start looking NOW at the different colleges. I don't think that transferring into a program from another is that easy!!!!!!
