In January 2010, the FINA Bureau approved the swimming qualification system for the 2011 World Aquatics Championships.
The qualification meets included continental championships in 2010 and 2011 (e.g. European Championships, Asian Games, Pan American Games); and international competitions approved by FINA in advance.
The qualifying system for individual events was similar to what is employed for the Olympics.
This limitation remains; however, if a country wished to have more than one male and one female swimmer in up to 2 events each, then an athlete(s) had to meet one of two standards: The swimming competition featured races in a long course (50 m) pool in 40 events (20 for males, 20 for females; 17 individual events and 3 relays for each gender).
The evening session schedule for the 2011 World Aquatics Championships[3] is shown below.
