Payments on account will be applied to charges based on the priority set within the fee payment system. Tuition, fees, meals and rent are set to be top priority under federal regulations and ISU procedures. Scholarships, third-party payments, and exemptions may be set to apply only to the specific charges they are authorized for. Federal financial aid may have limits on charges the aid can be applied to, and therefore may generate a refund in spite of outstanding prior or nonqualified charges. Many scholarships will apply to any outstanding charges and are eligible for refunds. Outstanding housing charges for the term will generally be paid to the extent of the financial aid before a refund would be generated.
