The National Panhellenic Conference is an organization established to foster interfraternity relationships, to assist collegiate chapters of NPC member groups and to cooperate with colleges and universities in maintaining the highest scholastic and social standards.

In 1905, ZTA President Bruce Houston Davice attempted to secure ZTA's admittance into the Intersorority Conference (now NPC). At this time, the Conference had entrance requirements that Zeta Tau Alpha could not meet: All chapters of a sorority in the Intersorority Conference had to be on campuses of an A rating (i.e. those offering a four-year degree program). This was heartbreaking news to all Zetas.

Although a difficult decision, the ZTA 1906 Convention went through the necessary formalities of charter revocation of the chapters that did not meet the requirements of the Intersorority Convention. Thus, our birthplace, Alpha Chapter, became dormant for 43 years. (It was later re-opened when Longwood University became an accredited four-year institution.) Also lost was Eta Chapter at Mary Baldwin College.
