National history Part 2

The Kappa Kappa Psi delegates at the 1947 Fraternity Convention officially voted to accept Tau Beta Sigma as a "sister organization" of the Fraternity and offered this new organization the privilege of sharing all fraternal publication, National Office operations, staff personnel, and other fraternal programs.

The Silver Anniversary of Tau Beta Sigma was celebrated at the 1971 National Convention. The concert march, Tau Beta Sigma, by Donald I. Moore, was commissioned to commemorate the founding of the Sorority. During the 1970's, Tau Beta Sigma continued to grow. Participation and service at the local district, and national levels helped to improve the lines of communication between the National Council and the Active membership. In 1977, all former membership restrictions were removed and chapters were afforded the opportunity to initiate male members of the band. In addition, the national fee structure was aligned and all former debts of the Sorority were eliminated. The Gamma Kappa Chapter at the University of Connecticut was the first coed chapter by more that one year.

During the 1980's, Tau Beta Sigma adopted national policies on hazing and alcohol. The geographical districts were restructured and renamed, and the Ritual of Tau Beta Sigma was revised to reflect the changes in the membership of the organization. A membership development program was also implemented, providing chapters with suggestions and information on the recruitment and education of Prospective Members and Candidates.

In 1995, a Mission Statement was created and then in 1997 a Strategic Planning Team was formed to allow the organization to participate in long-range planning and goal setting.

Tau Beta Sigma continues to grow and flourish in the 21st Century by reflecting the changes within the membership, society, and the needs of American Bands.
