Rush week, also referred to as recruitment week, is a period of time during which students are recruited by sororities and fraternities to their respective Greek letter organizations. Rush week typically occurs at the beginning of the school year, but some schools may rush during summer or spring.
Rush week is usually very organized and fast-paced, and although practices differ by institution or Greek organization, it always involves familiarizing students with Greek life. For fraternities, rush week tends to be less formal and includes events, such as rush parties, dinners and sporting events. Rush week for sororities is more formal and involves activities, such as brief social receptions, formal dinners and interviews. This period of recruitment concludes with bids, which are invitations from sororities or fraternities given to those being asked to join.
