Pupils will learn what it was like to fight in a war at the age of just 13 when former child soldier Ben Okafor visits their Berkshire school.
Ben Okafor says music helped him deal with his experiences
Mr Okafor, now a singer/songwriter, will be working with Year 10 pupils at Leighton Park in Reading over the next three days.
On Wednesday he will be performing with the pupils at a school concert.
During his early teens Mr Okafor served as a boy soldier in the Biafra army during the Nigerian civil war.
He believes that music has helped him come to terms with what he experienced and is a supporter of the Coalition to Stop the Use of Child Soldiers.
John Dunston, head of Leighton Park, said "We are privileged to welcome Ben to Leighton Park.
"He is an heroic reminder of the horrors that thousands of children have to endure - it is our responsibility to help tackle this abuse of humanity.
"It is particularly poignant for our pupils to realise that what he suffered took place when he was the age that they are now, happily enjoying their education and full of potential and zest for life."
