You are right. California does not recognize EC's ADN or any other nursing degrees if it is for INITIAL licensure.
If you are not an RN, but use EC's ADN program to get initial RN licensure in another state, you will not be eligible for licensure in California. I believe the cutoff date was in December 2004. I may be wrong. But I think that's the date, cause I registered/enrolled with EC just a few months afterwards and I was warned by EC I would not be able to get licensed in California. I didn't care, as my whole family lives midwest/east coast, and I won't move.
Even if you practice as an RN in another state, California has stated it won't recognize your license.
There are a lot of threads on this in the distance learning forum, and this discussion often gets heated.
There are more and more state boards who are restricting licensure for EC RN's. The best thing to do is contact the BON in your state. Things change over time, and a list from a few months ago may no longer be accurate. I believe Maryland was the latest state board to no longer accept EC RN's.
The best advice I could give you is to check with the BON's in the states you will most likely live in, if you are planning to move.
Every individual has to decide what will be the best plan for them, whether that is going through EC's program, or a more traditional school. Everyone has different needs and wants, and the decision must be an individual one.
Good luck to you. And check out the threads in the Distance Forum. There are EC students and graduates that post frequently in that forum.
