Hippology consists of four phases: horse judging, written examination and slide identification, ID stations, and team problem-solving.
Many youths across the United States and in other countries compete in hippology annually, showing their knowledge of all things "horse".
Items covered in the contest may cover any equine subject, including reproduction, training, parasites, dressage, history and origins, anatomy and physiology, driving and harnessing, horse industry, horse management, breeds, genetics, western games, colors, famous horses in history, parts of the saddle, types of bits, gaits, competitions, poisonous plants, and nutrition.
Unlike the horse judging competitions, hippology competitors are not expected to give reasons, but only place the classes.
Members are judged on their teamwork (especially during the discussion phase), the accuracy of their solution, and their presentation skills.
