APO rush varies from campus to campus, on my campus rush is three day period that consists of a social event, service project, and a leadership project to show what APO is all about. By, the third day if you're still interested you can join, we do not and cannot cut. At initiation, the meaning behind our coat of arms is revealed, also more background history. NO HAZING!

BTW, I noticed that you are also interested in joining an IFC (social) fraternity. If you didn't know, you can be both an APO and in a IFC fraternity at the same time. Membership with the two does not conflict with each other.
