Not Retroactive
Fee Assistance Program benefits are not retroactive. Benefits may only be applied after the Fee Assistance Program benefits have been awarded. No refunds will be issued for any fees paid before you have been approved for the Fee Assistance Program. Also, you will not be able to use your awarded medical school designations if your AMCAS application was submitted before your Fee AssistanceProgram application was approved. The AAMC is not responsible for any MCAT registration deadlines or medical school application deadlines you may miss while waiting for the review of your Fee Assistance Program application. If you have questions about whether your Fee Assistance Program benefits will be applied, contact AAMC before making a purchase
