Great Britain is to field a trio of athletes at the women's World Cup Final in London on 9-10 July.
Mhairi Spence, Freyja Prentice and Heather Fell will all be representing their country at the event.
The Word Cup Final, which takes place at Crystal Palace and Greenwich Park, will provide an opportunity to qualify for the 2012 Olympics.
But fellow British pentathletes Katy Burke and Samantha Murray just failed to qualify for the contest.
Qualification for the final took place in a series of World Cup events and Great Britain is one of only six countries to have the maximum of three women represent it in the event.
Pentathlon GB performance director Jan Bartu said: "I had expected us to qualify three women given the depth of the British team. They now need to stay healthy and get ready to compete. It will be a great test for them.
"It would be fantastic if one of them could win and qualify for the Games, but the top athletes in the world will be competing, so nothing is set in stone."
Inverness athlete Spence finished second in the overall 2011 standings, with Inverurie's Burke finishing third and Devon's Fell ending up in fifth spot.
Spence, 25, said: "I'm really pleased to be going to the World Cup Final. It's the first Olympic qualifier but there's only one Olympic spot there, so it will be quite hard to get it."
Germany's Olympic champion Lena Schoneborn topped the World Cup standings, with Brazil's Yane Marques the only other non-Briton in the top-five. She came fourth overall.
The winner of both the men's and women's competitions at the World Cup Final achieve a quota qualification place for London 2012.
The top eight finishers in the men's and women's competitions at the European Championships at Medway in Kent from 28 July to 1 August 2011 will also achieve qualification places for 2012.
Meanwhile, British men's hopeful Jamie Cooke finished 18th in the World Cup 4 in Chengdu, China, after a poor shooting round.
The 20-year-old from Cheltenham will now have to wait to find out whether he has made it into the GB men's team for the Final.
