The year 2012 marked the 100th anniversary of the San Diego County Branch of the Music Teachers’ Association of California (MTAC). As one of sixty-seven branches throughout California, the San Diego County Branch (MTACSD) offers competitive and non-competitive programs—at both the local and the State levels--that encourage community involvement, musical growth, skill development, and student recognition. Each year, more than 1500 students of MTACSD teachers participate in the events sponsored by the Branch.

The Music Teachers' Association of California is a professional organization of approximately 4,700 members. Since 1897, MTAC has dedicated its efforts towards the pursuit of excellence in music education. The mission of the MTAC is the establishment of excellence in the music teaching profession through high standards for membership, strong ethical values, and the continuation of musical education by its members to cultivate personal, professional, and artistic excellence.

Every year, MTACSD teachers participate in the annual State MTAC Convention. Additionally, students from various MTACSD teaching studios are selected to perform at the five-day event, in recitals and master classes that highlight outstanding students.
