The Right Track National Initiative will offer its services to police, local authorities, HM Prison Service and Youth Offending Teams.
A £165,000 grant from the Department for Education and Skills will pay for the service for the first two years. After that, the charity will charge for it.
The consultancy has its origins in the Children's Society's Right Track project in Bristol, which has been working with black youths in the city since 1998, in response to concerns about stop-and-search practices, custodial remands and sentencing. Since its launch, reoffending by young black people has decreased by 17 per cent.
The national project will provide training to statutory agencies on reducing discrimination and will work with young people on issues such as conflict and anger management.
Sue Wilson, co-ordinator for the Right Track National Initiative, said the project would involve educating more people about black history. "Young people tell us this is missing," she said.
"But we are looking forward to sharing our expertise with agencies throughout the country to reduce offending and improve the lives of these young people."
