Cancellations of appointments must be made directly with Pearson VUE. If you fail to appear for the scheduled test, arrive more than 15 minutes after the scheduled start time, or change or cancel your appointment within 24 hours of the test date and time, you will not receive a refund and the fees will not be transferred to another test administration. If there is an emergency, you must send a written explanation and documentation to the NBCRNA.
