WCF World Rankings
The WCF World Rankings system is designed to track and list the amount of success achieved by each member association of the World Curling Federation in a given curling season. The system, which was implemented in December 2006, is similar to the ranking system used by FIFA. The events taken into account when calculating each nation's score include the Olympic and Wheelchair [curling at the Winter Paralympics|Paralympic] games, the World Curling Championships, and the various qualifying events for member associations who did not compete in the worlds. The system was developed by Patrick Hürlimann, who is a former List of [Olympic medalists in curling|Olympic champion] and was the vice president of the WCF from 2010 to 2012. The calculation method was overhauled for the 2018–19 season.
