The Prince's Trust aims to raise "tens of millions
in funding this autumn to expand a pilot project teaching literacy and numeracy skills to young people.
The trust is currently undertaking a £5 million pilot project, funded by the Learning and Skills Council, to help young people, including the long-term unemployed and offenders, find jobs.
The pilot is based on the Prince's Trust's existing young people volunteers' programme which has been running for 16 years, but places more emphasis on writing and maths skills.
The pilot will be evaluated this autumn and a decision will be made whether to roll it out across the country later in the year.
A spokeswoman for the charity said that if the pilot project did go national, it would form part of a general revamp of the trust's volunteer programme.
"We are looking for funding in the tens of millions from the Skills Council and our corporate sponsors,
the spokeswoman said.
