Olympic Qualifying Event - Africa Apr 29 - May 7 (Casablanca, Morocco)
Qualification for will be based on the world ranking list prepared by the International Judo Federation (IJF) on 1 May 2012. The top 22 men or 12 women from the world rankings in each division qualify, subject to a limit of 1 judoka per NOC per division. Further continental quotas (Europe 25, Africa 24, Pan-America 21, Asia 20 and Oceania 10 across both sexes and all divisions) also qualify subject to an overall limit of 1 per NOC.
National Olympic Committees may enter up to 2 qualified athletes in each individual event if both meet the Olympic Qualifying Time (OQT). 1 athlete per event can potentially qualify should they meet the Olympic Selection Time (OST) and if the quota of 900 athletes has not been met. NOCs may enter swimmers regardless of time (1 swimmer per sex) if they have no swimmers meeting either standard entry time.
The qualifying time standards must be obtained in Continental Championships, National Olympic Trials or International Competitions approved by FINA in the period March 1, 2011 to July 3, 2012.
A country is allowed a maximum of three athletes that reach the 'A' standard in an event who meet or exceed this mark in the 18-month period prior to the Olympics. The 'B' standard is slightly easier to reach, but only one additional athlete per nation may be entered who has met the 'B' standard without pushing on to the 'A' standard.
The qualification period ends on 8 July 2012.
