Two hundred and sixty jobs are to be axed at Kent County Council (KCC) in a major reorganisation to save £8m.
KCC said it followed a detailed review of how to make services within the Children, Families and Education department more effective.
The loss of the posts is an overall staff reduction of 7%, but 100 posts are vacant and will not be filled.
KCC said the changes, to be effective from September, would "protect and enhance services".
It said the proposals would ensure KCC carried on "delivering the very best" for the 300,000 children and young people, and their families, and high quality support for early years providers, schools and colleges.
Managing director for children, families and education, Rosalind Turner, said: "The overriding purpose of the restructure is to organise the team in a way that can best meet our priorities and respond to the needs of children and young people in Kent.
"I firmly believe it will leave us best placed to manage the challenges we face and fulfil our commitment to the county's children and young people."
