Membership in Sigma Xi is by nomination and is conferred in one of two ways. While paraphrased here, full information regarding how to become a member is available on the Sigma Xi Web site . Please indicate on the front of the nomination/application form for
which type of membership the nominee should be considered.
Full Membership is conferred upon any individual who has shown noteworthy achievement as an
original investigator in a field of pure or applied science or engineering. This generally requires at least
two first-authored, refereed papers or patents, one of which can be a PhD thesis. Life experience is also
considered in some instances. For nomination to Full Membership, either attach a CV or résumé OR provide a separate
attachment with the following information:
- Education: Institution(s), date(s), degree(s)
- Professional Positions: Institution(s), date(s), position title(s)
- Publications: Titles, authors, dates, source(s) (journal name, thesis, etc.)
Associate Membership is available to any individual who has, through initial research achievement in
a field of pure or applied science, shown an aptitude for research, as evidenced by independent
investigation ordinarily resulting in a written report. Associate membership is offered to encourage
young investigators with promise to continue careers in research. For nomination to Associate
Membership, attach a brief statement regarding the nominee’s involvement in research and potential
research aptitude.
