Select a film that is appropriate for your department or one that is meant simply to be entertaining offering attendees a chance to loosen up and enjoy a film together with peers and colleagues. For example, if you are hosting a luncheon for the history department, a rare film on a historical subject or a biography of a historical figure would be appropriate.
Invite one or more speakers to your luncheon to give a short presentation or simply to answer questions. You can also invite special guests to your luncheon to allow students a chance to mingle with individuals who can offer special insights into the field that students are intending to pursue.
Another activity to consider after lunch is a chance to view a special exhibit developed for the luncheon, for instance, an art show of graduate students' work. Alternatively, presentations by students or faculty can be an opportunity for students and faculty attending the luncheon to share ideas with those outside their fields.
One way to attract potential students to your graduate program is to supply them a glimpse into what your graduate school or a specific program has to offer. This could include an overview the specifics of the program or department along with a chance to observe the type of atmosphere and faculty-student dynamic that exists in the department to help potential students decide whether to apply to that department.
