To audition for Colorado All-State Choir, students must be a junior or senior and must be currently enrolled in their high school vocal music program.(Note: homeschooled students are required to be enrolled in their local high school's vocal music program to audition.) Auditions are held each fall to place students in one of three choirs to perform in the spring. Auditions are scored on a point system using a variety of qualified judges from the Colorado region. Raw scores are then configured into "Z-Score" to account for different judges and voice parts.

Each student will receive a RAW SCORE out of 100 possible points. That score will then be calculated into a "Z-Score" to account for the different judges, their averages, and the amount of students that are needed for each choir. The "Z-Score" cut off is different for each voice part, and will change every year.
Colorado ASC runs audition tabulation based on a function called Z score. First, all students from a particular judge are listed and compared with the average and standard deviation of that judge. The standard deviation shows the score spread for each judge. The judge's average score less the student's Raw Score is divided by the judge's standard deviation. The result will be a number roughly between -2 and +2. This number is the student's "Z Score." The average scoring student from that judge will receive a "z score" near zero. The Z-score allows for the best mathematical method to account for the varying difficulty of a judge's scoring. As a result, a student's raw score from one judge can produce a seemingly different z score than expected. The score cut offs for the choirs are made by "z score."
The formula is:
(Student Raw Score -Judge's Average Score) / Standard Deviation of Judge = Z Score
