Upon receipt of a timely request for a hearing, the administrator of financial services or the person designated by the president shall have the records and files of the college available for review and shall promptly hold an informal hearing to determine whether the individual in fact owes any outstanding debts to the institution. After the informal hearing, a decision shall be rendered by the hearing officer indicating whether in fact the institution is correct in withholding services. Notification of this decision shall be sent to the individual within five regular college business days after the hearing. Such hearing shall constitute a brief adjudication proceeding as established by the Administrative Procedure Act at RCW 34.05.482 through 34.05.494.
