On Tuesday 8 May 2012 BBC World Class, in collaboration with the BBC World Service global conversation programme World Have Your Say, will be holding the World's Biggest School Assembly on the BBC and we want your school to be involved.
More than one billion children attend school - we want to hear from them.
Over 24 hours, the BBC will provide a platform for schools across the globe to debate and discuss, share concerns and ideas about what really matters to them. And we want your school to be part of it.
BBC World Service will be live in schools all over the world with special news bulletins on air throughout the day. Your school can interact live on the BBC website, find out what is important in other schools, and share what your pupils are doing.
Sign up today and let the BBC know what you're planning. All schools which take part will receive an exclusive BBC e-certificate.
