To determine an athlete’s class, classifiers observe athletes as they perform a variety of movements used during the sport of wheelchair rugby. Firstly, classifiers test athletes’ limbs for strength, flexibility, sensation, and muscle tone; and athletes’ trunk for balance, ability to bend over and rise up and the ability to rotate to both sides. The athlete is then observed performing both ball handling and wheelchair skills prior to game play and during game play, if necessary.  In addition, the athlete’s execution of ball and wheelchair handling skills are observed on court during actual game play. Typically, an athlete is assigned a class following the completion of the bench test and the functional skills test prior to game play. The athlete’s execution of ball and wheelchair handling skills are observed on court during actual play to make a final determination of athlete’s class. Classification is an ongoing process. When an athlete starts competing, they are allocated a class that may be reviewed throughout the athlete's career.
