The classification rules of the International Federation for Wheelchair Tennis state that athletes with a physical impairment that affects their ability to move around the court and prohibits them to compete equally with able-bodied tennis players are eligible to compete in the sport at the Paralympics.
Classification also groups athletes in classes, defined by the degree to which they are limited in their ability to perform activities within that sport. In Wheelchair Tennis there are two classes, Open and Quad:
- Open class is for athletes with an impairment of one or both legs but does not affect their arms or hands.
- Quad class athletes have an impairment that affects their arms and legs, which limits their ability to handle the racket and to move their wheelchair compared with Open class athletes. Men and women compete together in the Quad events.
