What is Sigma Chi?

Sigma Chi is a brotherhood with roots in the collegiate experience that engenders a lifelong commitment to strive to achieve true friendship, equal justice and the fulfillment of learning as part of our overall responsibilities to the broader communities in which we live.

We achieve these ideals through the practice of character qualities embodied in our Ritual, and continuously reaffirm our purpose through the observance of Sigma Chi’s Governing Laws and through adherence to the decisions of our legislative assemblies, which empower and direct our leadership. 

In addition to its 233 undergraduate chapters and 126 alumni chapters, Sigma Chi is comprised of four operational entities: the Sigma Chi Fraternity, the Sigma Chi Foundation, the Risk Management Foundation and Constantine Capital Inc.

Fundamental Purpose

The fundamental purpose of the Sigma Chi Fraternity is the cultivation, maintenance and accomplishment of the ideals of friendship, justice and learning within our membership.

Sigma Chi Fraternity best serves its purpose by developing, implementing and monitoring programs that foster leadership, build character and promote positive relationship skills which, in turn, enable our members to become productive and caring participants in their families, colleges and communities.

Core Values, Vision and Mission

Sigma Chi’s core values are friendship, justice and learning. Our vision is to become the preeminent collegiate leadership development organization—aligned, focused and living our core values.
