In North America, fraternities and sororities are social organizations at colleges and universities. They are sometimes collectively referred to as Greek life. Generally, membership in a fraternity or sorority is obtained as an undergraduate student but continues thereafter for life. Some accept graduate students as well. Individual fraternities and sororities vary in organization and purpose, but most share five common elements:
- Secrecy
- Single-sex membership
- Selection of new members based on a two-part vetting and probationary process known as rushing and pledging
- Ownership and occupancy of a residential property where undergraduate members live
- A set of complex identification symbols that may include Greek letters, armorial achievements, ciphers, badges, grips, hand signs, passwords, flowers, and colors
Racism in United States college fraternities and sororities has been linked to the experience of microaggressions, fewer opportunities to use the networking system built into Greek life, and harmful stereotypes. This fuels the experiences of people of color throughout their lives in various academic, work, and personal spaces, including Greek Life Organizations (GLOs). Many have argued that through the creation of these organizations, there has been a legacy of racism, which has fueled the elitist structure that has negatively impacted people of color the most.
The National APIDA Panhellenic Association (NAPA) is an umbrella council for twenty Asian, Pacific Islander, and Desi American fraternities and sororities in universities in the United States.
