As the program grew, it eventually split off and the Children's Chorus of San Antonio was officially created as an independent musical non-profit organization in 1993.

CCSA’s programs are divided into three divisions: Beginning, Intermediate, and Advanced Ensembles CCSA's core ensembles provide a rigorous curriculum of performance-based instruction ranging from the basics of vocal technique through an extensive and diverse repertoire.

Concert Choir, Chamber, and Encore are all directed by CCSA's Artistic Director, Dr. Ryan Garrison.

Neighborhood Choirs are year-round programs for students in grades 3-8, guiding them to sing, work as a team and find their voice both musically and individually.

Through this program, children and their accompanying adults share songs, rhymes, movement and instrument play in a non-performance-oriented environment.

Founder Marguerite McCormick and CCSA have championed new music for children’s choirs by commissioning numerous works including the Scarecrow Pieces by Joan Whittemore in May 1999, jointly commissioned by UTSA and CCSA, The Present by UTSA professor Dr. James Balentine received its premiere in October 2003.

Composer David L Brunner was in residence with CCSA choirs in May 2005 for the premiere of his piece, Then, Now, Forever, commissioned in memory of Tour Director Robert E. “Bob” McCormick.

In addition to presenting its own concert series, CCSA regularly sings with the San Antonio Symphony and San Antonio Mastersingers, and has performed alongside the Texas Bach Choir, the UTSA Choirs and Orchestra and the United States Air Force Band and Singing Sergeants.

The chorus is known globally as well[citation needed], having collaborated with children’s choirs from the Czech Republic and Germany.

These tours have taken the Advanced Ensembles to east- and west-coast North American destinations and to Europe, including England, Scotland, Denmark, Italy, and France.
