The Olympic Games, which are held every four years, are the most prestigious competition in figure skating. Gold, silver, and bronze medals are awarded to the world's best soloists, couples, and dance teams in their respective categories. The International Skating Union (ISU) also holds annual competitions known as World Championships. The ISU has three levels of events: senior, junior, and youth. At the senior level are the Olympics and the World Championships. At the junior level are the European Championships, North American Championships, and Australian Championships. And at the youth level are the Novice Levels and the Pre-Qualifier Levels. At the senior level, there are two divisions: men and ladies. A team consists of five skaters, with three of them on the ice at one time. Each team tries to win gold, silver, and bronze medals. The individual event is called the championship after its three highest scoring skaters advance to the next round. They are called pairs, triplets, and singles depending on how many people they include. The last man or woman on the ice determines the ranking of all participants. At the women's event, there are also two divisions: ladies and novice. Like the men, each lady or novice team is made up of five skaters, with three on the ice at one time.
