Belen,
The number one question, right? And now, you simply must give them the correct response, or as Cynthia pointed out, direct them to the catalog and to the department best suited to respond.
How about the disclosures on your websites? These are regulations that are now required and I would suggest that you also familiarize yourselves with these as well. Students may have questions about them for you as well.
