 The updated format is based on the structure of the European Six Nations Championship, coinciding with each other in February and March of each year.Prior to this, the last competitive tournament to be held across the Sudamérica–RAN region had been the PARA Pan American Championship, which had ceased after its 2003 edition.World Rugby has granted all matches with test match status, with caps awarded for every match, though matches against the Argentina XV (rather than the top Argentina national squad) will not affect the World Rugby Rankings.
