Sigma Xi Membership Categories
How Do I Become a Sigma Xi Member?
- Through the Committee on Qualifications on Membership (CQM). If you wish to self-nominate for membership or have one Sigma Xi nominator, you can request that the Sigma Xi Committee on Qualifications on Membership review your application for membership.
- Through a local Sigma Xi Chapter. If a Sigma Xi chapter is located in your local area, you can request that Chapter’s officers review your Sigma Xi nomination.
NOTE: Please only submit your nomination once - either through CQM or local chapter. If you submit your nomination in both places, you will impede the processing of your membership.
