Here is an excerpt from the Pi Phi delegate's report of the 1947 meeting:
(The names were in Greek and I typed them)

After reviewing the entire situation calmly, with no feeling of "pressure," and with a deep consciousness of the democratic right of NPC to remain the type of group which it had been for the more than fifty years during which it had built up international recognition for leadership and service, NPC, by unanimous votes in all cases, admitted to associate membership Alpha Epsilon Phi, Phi Sigma Sigma, Delta Phi Epsilon, Sigma Delta Tau and Theta Phi Alpha and granted associate membership to Alpha Sigma Alpha, Alpha Sigma Tau, Delta Sigma Epsilon, Pi Kappa Sigma, Sigma Sigma Sigma and Theta Sigma Upsilon, contingent in each case, upon the elimination by June I, 1948, of all chapters on campuses not meeting NPC educational rating requirements and of all dual memberships involving NPC fraternities.

Beta Gamma was not one of the other five sororities admitted.
