The Interscholastic Equestrian Association (IEA) is an organization that promotes equestrian competition for middle and high school students. IEA offers a unique format where riders do not need to own their own horses, as they compete on horses provided by the host facility. The horse is new to the rider, and the scores are based on equitation. Participation in IEA allows students to gain competitive riding experience regardless of their access to horses and resources.
