Pony Clubs are places where young people can learn about horses. There are 600 in the US alone.
From the United States Pony Club website:
“Pony Club provides opportunities for instruction and competition in English riding, horse sports and horse management for children and young adults up to 25 years of age. The term “pony” reflects the age of the members, rather than the size of the mount. Horses and ponies of many different breeds, shapes, and sizes are seen in Pony Club activities.
It is not necessary for a child to own a horse or pony, but they must have access to one when required. Programs are offered in dressage, eventing, show jumping, mounted games, tetrathlon, quiz, vaulting, foxhunting, and polocrosse.
During “unmounted” meetings members learn about feeding, shoeing, veterinary care, and other areas of horse management. Under adult supervision, the more experienced Pony Club members instruct and assist younger members.
Pony Club members are encouraged to work their way through the nine stages of the progressive Standards of Proficiency, which test knowledge and riding ability. Pony Club members who attain the B, H-A, and A rating levels meet standards of competence that are recognized throughout the horse world.”
