Similar women's organizations at Colorado University and the University of Oklahoma submitted petitions to join with the Texas Tech and O.A.M.C. chapter prior to the official charter being received. On March 26, 1946, a charter was granted by the Department of State for the State of Oklahoma legally establishing “Tau Beta Sigma, National Honorary Band Sorority,” later amended to “Tau Beta Sigma.” On May 4 of 1946, the members of the Alpha chapter traveled to Lubbock, Texas, to officially install the women of Texas Tech as the Beta chapter of the National Sorority.
