If you're a student in grades 6 through 12 and are interested in equestrian competition, the MiraBella IEA team is the perfect place for you! You may be asking what exactly is IEA? IEA is the Interscholastic Equestrian Association. From the IEA website - The unique aspect of the competitions, both at the local and national level, is that none of the riders will supply their own horses or tack. Instead, the host team arranges for the horses and equipment. Since the horse is new to the rider, the scores are based upon horsemanship and equitation. All disciplines offer a variety of ability levels from beginner through advanced. The IEA has set guidelines for the placement of new riders entering the IEA to allow for the unique program format of riding an unfamiliar horse.
