The Big Lottery Fund is looking for a partner to help it deliver a new £25m programme aimed at reducing youth crime.
The UK-wide Realising Ambition programme is designed to fund replicas of projects that have been successful in diverting young people from crime.
A statement from the BLF said the UK partner was likely to be a group of organisations working together and would be led by a major voluntary and community sector organisation.
The programme will identify 20 to 30 programmes across the UK that have helped people aged from eight to 14 who are at risk of offending.
Up to £3m will be available per project for grants that will last for between three and five years, to help replicate or increase it in size.
The partner organisation would be eligible to receive up to £1m of the £25m to cover costs.
A spokeswoman for the BLF said the first step was to find a partner to help deliver the programme, which it hopes will provide specific policy and practical expertise.
The deadline for applications to become the partner is 23 June. After this, the BLF and the chosen partner will work together to identify the projects that they want to fund.
Anna Southall, interim chair at the BLF, said it was trying to take a more systematic approach to implementing best practice.
"We will also commission a rigorous evaluation of the impact and value for money of our investment in replicating these models to see what wider lessons might be drawn for BIG and other funders," she said.
For charities that are interested in becoming the partner, there is a briefing event on 26 May. Interest in attending must be registered by contacting realising.ambition@Biglotteryfund.org.uk by 23 May.
