Founded in 1959, the American Choral Directors Association (ACDA) is a nonprofit music-education organization whose central purpose is to promote excellence in choral music through performance, composition, publication, research, and teaching. In addition, ACDA strives through arts advocacy to elevate choral music's position in American society.
ACDA ISU is an active chapter that promotes the study of the choral. Memebers meet to discuss conducting techniques and share ideas. Members also attend the national ACDA conference which is held every other year.
