Many of our members are Nobel Laureates, arguably the most prestigious international award one can receive. Membership is for life.

Membership is extended to both men and women, graduate and undergraduate students. Alpha Chi Sigma has also a professional branch, which includes members of Alpha Chi Sigma who are not on membership roll of a collegiate chapter. Professional candidates can become members of the Professional Branch even after they have completed their studies.
