Every sport has a different governing body that can define the way that the sport operates through its affiliated clubs and societies. This is because sports have different levels of difficulty and skill, so they can try to organize the people playing their sport by ability and by age. The different types of sport governing bodies are all shown below:
International sports federations are responsible for one sport (or a group of similar sport disciplines, such as aquatics or skiing). They create a common set of rules and organize international competitions. The promotion of the sport are also a task of an international federation.
National federations have the same objectives as an international federation, but within the scope of one country, or even part of a country, as the name implies. They support local clubs and are often responsible for national teams. National Olympic Committees and National Paralympic Committees are both a type of National Federation, as they are responsible for a country's participation in the Olympic Games and in the Paralympic Games respectively. However, a national governing body (NGB) can be different from a national federation due to government recognition requirements. Also, NGBs can be a supraorganization representing a range of unrelated organizations operating in a particular sport as evident in the example of the Northern Ireland Federation of Sub-Aqua Clubs.
Multi-sport event organizers are responsible for the organization of an event that includes more than one sport. The best-known example is the International Olympic Committee (IOC), the organizer of the modern Olympic Games. General sports organizations are responsible for sports related topics, usually for a certain group, such as the Catholic or Jewish sports groups. General sports organizations can also exist for the army and other groups, but they usually are medium-sized, as they do not have that much of a budget to work with.
Professional sports leagues are usually the highest level of play in sport, specifically if they consist of the best players around the world in a certain sport. Because of this, they usually work with national or international federations, but there is usually a separation between the different federations. Most North American professional leagues usually do not have amateur divisions, as the amateur divisions are mostly run in separate leagues. In addition, most professional leagues are related to other leagues, as players usually attempt to play in the league with the highest level of play. Because of this, promotion and relegation can occur; or, in league systems without promotion and relegation, clubs in professional leagues can have a team in the minor leagues. This enables them to shuffle players who are not doing well to the minor leagues, which will inspire them to contribute more to the team by playing better.
