The qualification system was similar to that used for previous Games, with a fixed number of quota places divided among the nations whose shooters place well at the top-level global and continental championships. However, due to new IOC regulations mandating that all qualification events take place during the last 24 months before the Olympics, no such quota places were awarded during the 2009 ISSF World Cup or the 2010 ISSF World Cup, leading to decreased interest in these competitions to the point where the 2010 competition planned for New Delhi had to be rescheduled and moved to Australia. The International Shooting Sport Federation announced that qualification would commence with the 2010 ISSF World Shooting Championships in Munich, which ended on 10 August, almost exactly two years before the Olympics.
