Like most of UCR's organizations, the Greek life is an informal and casual presence on campus. A large number of Greek groups are multicultural and officially part of UCR's ethnic programs. No special housing is available for Greeks, so any gatherings must be conducted in resident or off-campus dwellings. The party scene is controlled mainly by the fraternities and sororities, but it is possible to attend the parties without actually joining, though it is worth considering if you enjoy that sort of social activity.
Some non-Greeks are under the impression that Greek life is popular simply due to the partying, but mostly non-Greeks are indifferent toward fraternities and sororities; it's simply another organization to join. There are a number of organizations at UCR outside of Greek life that serve the needs and interests of students in other ways. The fraternities and sororities give students a different method of extending their social network, making long-lasting friendships, and overall, having some fun.
