To get your CNA license transferred, you need to get in touch with the Nurse Aid Registry in whichever state you have moved to and request for an 'Application for Enrollment by Reciprocity'. Although most states have reciprocity agreements with each other, not all do, so you will have to find out. If reciprocity agreement is present, you will not have to sit for a state exam for a license again. However, If the states do not have this agreement, you will be required to take the state licensing practical and theoretical exam again in the state to which you are transferring.
