Horses eligible for registration in the Half Arabian registry must have one Purebred Arabian parent. Horses with one Purebred parent may be registered in the Half Arabian or one of the other Arabian Derivative registries depending on the breeding of the other parent.
Half Arabians competing in Half Arabian classes will be judged on Arabian Type as well as conformation and movement.
Horses registered in the Half Arabian Registry must compete in Half Arabian classes where they are offered at a show. Where no Half Arabian classes are provided then horses registered as Half Arabians may compete in the classes offered for their base registry as noted on the Certificate of Registration eg Arabian Pony breeding and will be judged in those classes as per the rules pertaining to that registry ie not with an Arabian type component. Horses cannot compete in both Half Arabian and another registry classes at the same show.
