Sororities participate in formal rush so that non-affiliated women have the opportunity to learn about each chapter. One week after rush begins, women receive membership invitations through a mutual selection process. For fraternities, rush is a casual affair held every Fall and Spring . Chapters determine their own rush programs. Daytime activities involve lunches and athletics, whereas nighttime events range from Hawaiian theme parties to comedy nights.
Fraternities can offer invitations of membership at any point during the week.
NPHC and MGC organizations plan individual membership selection functions. Chapters of the NPHC, the historically Black Greek groups, and MGC, the multicultural Greek groups, select new members through a process known as membership intake. Alumni Involvement Graduation from the university does not sever one's ties from the fraternity or sorority with which they are affiliated. In fact, membership in a Greek letter organization lasts a lifetime. There are many opportunities for alumni involvement.
