A nonrefundable $15 registration fee is required for each person at the time of registration. This per-person fee is owed once during the school year and once in summer. Fall students returning in spring are not charged the fee in spring. One person registering for multiple activities owes $15. The fee for two siblings registered on one form is $30. This fee is used for many expenses, including the cost of background checks required by the university for employees who work with children.
