Really naughty kids will be asked to sign a good behaviour contract with the police to try to stop them ending up as adult criminals.
And the new government plan will see the 1,000 worst kids in England and Wales - starting from age 10 - getting specific help to behave.
The £218m scheme will involve one-to-one support from care workers.
If the kids don't stick to the contract, they could end up with an Asbo, an anti-social behaviour order.
An Asbo sets out rules to live by which try to stop you getting into trouble.
There will be 20 trial projects launched over the next three years.
Children's Minister Beverley Hughes said stepping in to help kids should help long-term: "We can spot early warning signs in young people and families where things are going wrong - poor parenting, lessons skipped and complaints about behaviour."
