It is important to know the school that you are working at: Know the policies and how to access the information. Know the different Departments and what their roles are at the school. Know "Who-is-who?" within the organization, it's good to match a face with the name as well, and if you can build a working relationship with the staff, then that's even better, especially if you bump into the staff while taking a student on a tour (to talk with them), it will benefit the prospective student.
