The first step to register for NCLEX-RN is to select a board of nursing where you wish to get your license. Then submit an application for licensure to the board of nursing of that state. Also get an eligibility letter from the board of nursing within 365 days of payment and registration. You also need to register for the exam with Pearson VUE. After receiving your Authorization to Test (ATT) letter, you can schedule an exam appointment.
