Between 2006 and 2012, 9% of all middle school choral entries in the Texas University Interscholastic League (UIL) Concert and Sight Reading Contest consisted of mixed choirs (N = 842) (Texas UIL, 2012a). Middle school mixed choirs pose unique pedagogical problems for directors. One such challenge lies in the determination of whether to perform Soprano Alto Tenor Bass (SATB) or Soprano Alto Baritone (SAB) literature. While a director must take into consideration the number, strength, and vocal independence of boys in the choir, the range of the part or parts and the students' progress in the voice change process are perhaps the most critical factors. The purpose of this study was to conduct an analysis of the UIL SATB and SAB middle school sight-reading literature from 2006-2012 and the corresponding UIL sight reading.
