At Penn State we do operate a “caution list” that is checked when each visit is approved. We record the school and chaperone names of any visit that is not positive in case that group should request a visit in the future. Typically, our office will follow up with groups who are going to be placed on the caution list detailing some of the instances that were problematic during the visit.
It is the responsibility of the chaperones to ensure that students are behaving appropriately. Tour guides and admissions staff reserve every right to end a visit that is not going appropriately.
