The Positive Futures Impact Report: End of Season Review will say that more than 100,000 young people have taken part in the scheme since it was launched in 2000. It will also show progress on engaging young women in the programme in 2004-05, with participation by young women up about a third, from 21 per cent the previous year.
More than three out of four projects said Positive Futures reduced antisocial behaviour, and two out of three said there was a drop in youth crime.
Almost all projects said they had increased young people's participation in sport and other activities.
The report marks the end of the current phase of Positive Futures, which was outlined in the Home Office's 2003 publication, Cul de sacs and gateways - understanding the Positive Futures approach.
From 1 April this year the charity Crime Concern is taking over the management of the programme from the Home Office, and will be deciding how to take the programme forward over the next two years.
Gary Stannett, who will be the director of the Positive Futures programme at Crime Concern, said: "The report sets the scene for us to move on." Crime Concern will produce a strategy document outlining its plans for the programme in late May.
