The NCLEX is the gold standard for nursing boards in all but 1 state. (I don't know which one.) But I know that the same exam is accepted in Ca. and S.C. My mom lives there. You will have to apply, and PAY THE FEE. All the state boards want to get in your pocket, but the rest of your education and testing is accepted.
Currently in Ca. we pay $80.00 for a 2 year renewable license. We are required to have a minimum of 30 CEUs in the 2 years. That usually isn't much of a trick, if you keep track.
I had one RN that wasn't keeping track, so she was in one of my classes to pick up the last 8 CEUs she needed the day before her license expired. She then drove to Sacramento the next day(450 miles) to go to the board and get the renewal, so she could keep working. We had a long chat about my study. (see below)
Good luck! When you get here look me up. My company is looking for good nurses. (like who isn't?)
