The World Thoroughbred Racehorse Rankings
(WTRR) are compiled by the International Federation of Horseracing Authorities (IFHA), an organization established in 2003 with headquarters in Paris
made up of members from around the world.
According to the IFHA website, "The IFHA World Thoroughbred Racehorse Rankings are the official assessment of the top performers. In 1977, France, Great Britain and Ireland published the first internationally agreed assessment of racing merit on behalf of the European Pattern Committee under the banner of the International Classifications. In 1985, Germany and Italy joined the system, to be followed by North America (both Canada and the United States) and Japan in the mid 1990s."
Like most commercial enterprises, Thoroughbred horse racing
has become part of the global economy
. As such, beginning in 2004, the organization of the world's most senior Handicapper
undertook an official end-of-season assessment of the top Thoroughbred
performers and produced the World Thoroughbred Racehorse Rankings which are published twice a year. Its January publication includes the end of season assessments of horses aged three years old and upwards which have either raced in, or been trained in, countries whose racing season runs from January 1 to December 31.
