Prior to the sixth day of instruction for a specific term, students have the right to request that directory information be kept confidential. Requests will be in force until the student notifies the Office of the Registrar in writing that the information is no longer to be restricted. On the sixth day of instruction, all directory information that has not been restricted by the student may be released without the student's prior consent. Nothing contained herein prevents the University from disclosing directory information as permitted in '3-603(c).
