If a boy with special needs misses education for more than a year, the council will pay his family £8,000 in compensation.
Bournemouth Christchurch Pool (BCP) Council has failed to provide adequate food for boys throughout 2022 and into January and February 2023.
The Local Government Ombudsman (LGO) said authorities had caused unfair treatment of the boy.
LGO said its investigation “resulted in improvements” to the service.
The boy's mother said he had become “very isolated” by not attending school and had fallen behind in his studies.
She also had to take care of him, which she said made her feel isolated and distressed.
The LGO has told councils to pay £6,000 for those who miss out on education throughout 2022 and a further £1,000 for those who miss out on education by January-February 2023.
It will also pay £500 for delays in amending the boy's care plan and a further £500 to recognize his mother's “inevitable distress and frustration”.
A Department for Education (DfE) review published in February found that special educational needs and disabilities (SEND) services within BCP services needed to be improved more quickly.
A council spokesperson said the authority was on a “SEND improvement journey” and working with parents, carers, children and young people.
“We are currently making significant improvements to our alternative provision processes to improve the life experiences of children and young people supported in the BCP sector,” they added.
“We are committed to ensuring we provide the best possible services for all children and young people with SEND and will do whatever it takes to achieve that.”
