"All AWS sport horses are evaluated on their own qualities and/or performance records. The AWS is open to all breeds of horses and ponies. Whether previously registered (would be recorded with AWS) or non-registered as long as the horse is breeding, training or participating in one of the four disciplines that the AWS supports (Dressage, Eventing, Jumping or Combined Driving). Types of Books
The Main Book, and Elite Book (see below) are maintained by the National Office for all registered and recorded horses. The registration provided is for the lifetime of the horse.
Main Book
For Main Book registered horses pedigree history is desirable, but not required. Main Book horses qualify through their own performance.
Elite Book
For Elite Book- pedigree/bloodline history is required. This history must provide evidence of four generations of proven, documented sport horse performance in one of the four sports supported by the AWS (see guidelines above). The horse that is to be registered is automatically included in the four generations.
Sport Pony
Sport Pony book provides a book for performance ponies. As this book grows in numbers they will have their own awards separated from the main book. There is a minimum size is 13.0 hands and a maximum for 14.2 hands."
