Children's services in Surrey which were rated as "inadequate" by Ofsted in 2008 have been given a clean bill of health, the county council has said.
Children's Minister Tim Loughton has confirmed in writing the government is ending its intervention in the county and lifting the improvement notice.
The council said it followed an Ofsted report which found a clear indication of progress in Surrey last month.
Councillor Peter Martin said the council had made steady progress.
He said Mr Loughton had written in his letter he was pleased that significant improvements had been made in a range of core safeguarding services.
Mr Martin said: "We have made steady and sustained progress since 2008."
He added: "This clean bill of health shows that the government believes we are successfully providing the people most in need with the care and support they require and we will continue to do all we can to show that the minister's trust is well placed.
"We know more still needs to be done and our determination to bring further improvements remains as great as ever. Our job is to do everything we possibly can to minimise the risks to children."
In March 2009, the council received a one-star rating, following an earlier critical Ofsted report on its children's services, which were rated as "inadequate".
It was one of four councils in England whose rating plummeted from three stars to one.
