Riding as a competitive sport for individuals with disabilities tests the rider's skills in controlling the regularity of the horse's paces and maintaining harmony, lightness and ease of its movements. This gives the horse the impression of doing in its own accord what is required of it. Each competitor is classified into different categories consisting of individuals with comparable disability. Riding competitions are held at the local, regional, national and international level. The National Disability Sports Alliance (NDSA) is the recognized national organization for Paralympic-style competition. The Competition Association of NARHA
(CAN) also promotes competitive equestrian opportunities. Internationally, the International Paralympic Equestrian Committee (IPEC) governs equestrian competition for individuals with disabilities.
