The College of Idaho is a small, private liberal arts institution with a long-standing history of academic excellence and a fraternal history spanning over 85 years. College of Idaho Greek Life consists of three national fraternities, three national sororities, and one local sorority. Membership in a national fraternity or sorority provides opportunities for students to broaden their educational experiences during their time at the College. The role of fraternities and sororities is to promote academics, enrich personal lives, and serve the community. The College of Idaho recognizes this role and encourages Greek contributions and presence.

Kappa Sigma

Forged in the timeless bonds of brotherhood, Kappa Sigma Fraternity has grown from a collection of five friends and brothers to a national network of hard-working, respectful, and social gentlemen. The College of Idaho Lambda Chi chapter of Kappa Sigma has drawn strength both from its roots in tradition and from the then unbreakable bond of brotherhood. We strive to prosper at the College of Idaho in any way we can by committing ourselves to our academics, both individually and communally, holding social events, and engaging in public service on and off the College of Idaho campus. We meet these challenges across the community out of a love for the College, for its people, and it's future. So while to some, Kappa Sigma may occasionally be the place to be, those who know this Kappa Sigma Fraternity know that its essence lies inside something much deeper: an intangible and unspoken commitment from one man to another.

Sigma Chi

Established at the College in 1988 as Sigma Chi Alpha, the group received its charter as the Kappa Lambda Chapter of Sigma Chi International on January 29, 1994. With over 40 members, the Kappa Lambda Chapter stays involved through philanthropy events like Miss C of I and Derby Days. Holding a strong focus on leadership, brothers of the fraternity can be seen around campus in student government, International Student Organization, on the football team, and more. With a strong emphasis on a high GPA and community service, Sigma Chi is an active organization at C of I, committed to making the campus and the surrounding area a better place.

Local Sorority

Sigma Epsilon

Sigma Epsilon was organized on January 5, 1923.

Sigma Epsilon is informally known as the SE's. The motto of the Sigma Epsilon Sorority is "What we are to be, we are becoming now." This phrase signifies that being a Sigma Epsilon sister means that you have chosen, the highest of quality, values, and ideals that will determine the rest of your life. Above all, the purpose of Sigma Epsilon is to promote friendship and sisterhood, the strength of character, academic excellence, and sportsmanship in all college activities, social activates, and health, both moral and physical.
