You may exchange any distance learning certificate for another topic, prior to downloading or accessing course material. We will simply apply your payment towards the new topic. However, if course material has been accessed, then it cannot be exchanged. Under no circumstances will NASP refund a student’s money AFTER seven (7) days of initial purchase for any reason. If it is seven days or less, student will be entitled to refund if he/she has NOT downloaded material minus a 20% processing fee.
