You may wonder who is eligible to earn the AAP credential. Any professional in the payments industry can work towards accreditation. If you have worked in ACH for years, you will add a highly respected qualification to your resume. If you are relatively new to the field, you will give yourself an edge over the competition. At a minimum, Nacha requires one year working in the payments industry before taking the AAP exam and recommends at least two years' experience. If you do not have one year's experience but still wish to take the exam you can request a waiver with signature from your employer or your Payments Association.
