Over the years the purpose of the organization has remained the same: the promotion of the highest standards of theatre throughout the State of Tennessee. To accomplish that purpose, the Association serves as a vehicle for communication through its newsletters and through its annual convention.

It provides members with workshops, programs and seminars and with the opportunity to meet, work with and learn from each other as well as from invited theatre professionals from other states. TTA also serves as a liaison between Tennessee, regional, and national theatre organizations.
