ACDA members represent more than one million singers across the United States. ACDA members teach choral music in public and private schools – kindergarten through senior high school – and at the college and university levels. They conduct a variety of choral groups, including boys' choirs, children’s choirs, men’s and women’s choruses, junior and senior high school choirs, college and university choruses, ethnic choirs, vocal-jazz ensembles, and symphony choruses. They also conduct choirs in their communities and in their places of worship.
