Over the two days the schools will receive a crash course in successful and sustainable partnerships from the British Council, while the pupils will work together to exchange ideas and develop leadership skills as ambassadors for the project.
The British Museum will also encourage delegates to explore the galleries and choose an object from the world collection which represents them or their partnership.
The winning schools will continue to work with the BBC to follow the stories of Olympic athletes with their new international twin schools.
Working with the BBC World Class team, schools will be able to share and compare ideas and experiences online and, on occasion, in the BBC's World Olympic Dreams broadcasts.
The British Council will support them to work with their twin schools and develop their partnerships throughout the lifetime of the project.
The initiative began last year when the BBC started to tell 26 stories of athletes on their journeys to the London Olympic Games in a project called World Olympic Dreams.
The Olympic Dreams School Search was launched in September 2010, where UK schools were given an opportunity to twin with an athlete's school.
Amanda Farnsworth, BBC London 2012 project executive, said: "We are thrilled the teachers and pupils from the World Olympic Dreams athletes' schools are coming to London to meet in person the schools they are twinning with across the UK as this activity is an integral part of the BBC's commitment to ensuring that the London 2012 Olympics Games leave a legacy for future generations.
"We hope this will be the start of a really rich and engaging relationship between the schools as they learn more about each other and about the athletes they are following in the run-up to the London Games."
Vicky Gough, from the British Council's Connecting Classrooms team, who helped judge the competition, said: "We're really excited to be welcoming all these schools from around the world to London.
"Building lasting international links between schools is at the heart of what the British Council does, and face-to-face contact like this is an important part of any relationship.
"We can't wait to see these partnerships grow and flourish, as the schools use the inspirational power of the London 2012 Olympics to work together, and learn about each other's countries and cultures."
Following the conference the twin schools will be invited to visit their British counterparts.
Mongolians will visit Berkshire as boxer Badar Uugan's school visits its new twin in Newbury, basketball superstar Luol Deng's former school in Croydon goes to the Shetlands and gymnast Shawn Johnson's school from Iowa, USA, will visit Wales.
