The sport’s classification system divides archers into three functional classes.
The standing class (ST1) is for athletes with no loss of function in their arms, but with some degree of loss of muscle strength, co-ordination and/or joint mobility in their legs. Impairment groups include athletes who are amputees, athletes with cerebral palsy and athletes classified as les autres. Archers in this class may choose to compete sitting on a stool or chair with their feet on the ground or standing.
There is also a W1 class for athletes who have tetraplegia or a comparable impairment. These athletes have only a limited range of movement, strength and control in their arms and legs. They compete in a wheelchair.
Archers in the W2 class have paraplegia or a comparable impairment. Athletes have limited mobility in the lower limbs. W2 athletes have full arm function. These athletes usually require a wheelchair for everyday use and compete in a wheelchair.
