The IJF Junior rosters are maintained for the purpose of athlete ranking and team selection for events that use the International Judo Federation (IJF) Junior Category, which is defined as Athletes "under 21 years of age during the current year." For 2013, these are athletes that are born in 1993 or later (1993, 1994, 1995, 1996, 1997, 1998.).
Points earned in Senior events and divisions in Junior events that conform to the IJF Junior definition, will be added to this roster.
On January 1 of each year these rosters are modified to eliminate those athletes whose year of birth have made them ineligible for Junior team selection.
