The Local Chapter Individual membership in TriBeta is through a chapter on the campus of a four-year accredited college or university. There are now more than 380 chapters offering their members activites and experiences that enrich and extend but do not duplicate the primary requirements for the biology major. The national constitution provides a framework for chapter activities, but each chapter is free to function in accordance with its own needs and school philosophy. A national officer visits each prospective chapter as part of the application process. Chapter programs typically include guest speakers, reports of research by members and departments faculty, field trips, maintenance of collections, community service and social gatherings.
Most chapters have a lounge or office on campus.
A faculty advisor provides continuity and experience to the student members. The University of Tulsa proudly supports a TriBeta chapter, Pi Alpha, which has been a part of the Beta Beta Beta organization since April 4, 1979. This chapter competes every year in the Southcentral Regional Tri-Beta conventions.
