Welcome to the desert!
Most of the Maricopa colleges now offer the CEP program, which is a 2-2.5 year hybrid degree of the ADN and BSN together. If you already have a bachelors you can even enroll in the hybrid Masters degree.
The program is called CEP, and it stands for Concurrent Enrollment Programs (in Associate-Baccalaureate Nursing). You need to fulfill all the pre- and co-requisites prior to submitting your application. That is all the pre- and co- requisites for both the community college and the University you choose. Currently there are, I believe, 6 Universities to choose from. It is worth noting that entry into this program is competitive and you do need a good GPA/excellent HESI scores to get a seat. However, it does mean you will graduate with a bachelors in under 2.5 years (or Masters if you choose that route).
In a nutshell, you attend the community college just as you would if you were in the ADN program (without the CEP part). Then, you will take your University classes primarily online with some of the Universities offering a few classes in person.
It's intense, yes, but given the demand for bachelor-educated nurses it is definitely worth it. Not to mention the amount of money it saves to go via community college.
For me, I started Block 1 in the community college in the spring semester (January) of this year. I am just now finishing up Block 1. However, I started my University portion of the course in the fall of 2017, so I had a semester done by the time the ADN at college started.
When (and if.....fingers crossed) I graduate, I will receive the ADN degree certificate from the Maricopa college, and the Bachelors from the University. Essentially what happens is that the University takes all the ADN credits and includes them into their degree, and adds it to the classes you take with them to make up the Bachelors degree. Hope that makes sense.
Anyway - in terms of practical skills and what you will know about actual nursing, it is now different really from the people who graduate with "just" the ADN, but future employers seem pretty keen so see the Bachelors degree, which is what pushed me to take it. I don't feel it makes you any more competent than those with the ADN; the advantage is you may get a slight edge in an interview for having the BSN (or Masters in your case, since you already have the BSN).
We're very lucky here in Arizona - this is a relatively new concept to meet the demands of the "nurse of the future" concept, so not many states offer the CEP-type degrees yet. Eventually, I am sure more will join in, but for now AZ is a bit of a pioneer!
