The Southern California School Band and Orchestra Association is a non-profit organization whose active membership is drawn primarily from educational institutions—elementary schools, junior high/middle schools, senior high schools, colleges and universities. Additional membership includes students and others (private instructors, business establishments) who are active in the musical community.

The association is dedicated to enriching the cultural environment by helping all students to develop a greater appreciation of music, providing students with the means for exploring both vocational and non-vocational opportunities in music, raising performance and adjudication standards, and improving teaching techniques.
