Late-payment penalties are assessed when students fail to pay their current charges by the due dates. A late-payment fee of $100 is charged to all unpaid accounts. Students with past-due balances may be dropped from classes and will not be allowed to move into on-campus housing until the account is paid in full, a payment plan is set up, or there is confirmed financial aid noted on the account.
