The mother of an 11-year-old schoolboy is teaching him at home - because he has a nut allergy and his new school planned to segregate him for safety.
George Hall-Lambert is being taught at home during the dispute
George Hall-Lambert has a nut contact allergy and can self-medicate in some circumstances.
But officials at Howden School, near Goole, East Yorks, decided to separate him because of safety concerns.
The school said there is a place available, but his mother said he should be in a mainstream class.
His mother Judith is teaching him at their home in the village of Eastrington until the segregation is resolved.
George started at the school at the beginning of September and his mother said she told a member of staff about his nut allergy.
Judith Hall-Lambert said: "He can have a reaction straight away and he starts to swell up, has breathing difficulties.
"If they don't know what to do in an emergency then George's life is at serious risk, he could actually die ...If it's not dealt with in the correct procedures."
In a statement the school said: "There is a full time place for George.
"However, George's mother declined to send him back to school as she was not satisfied with our proposals.
"In this instance we have followed advice given by the local authority and health professionals along with guidelines issued by the Department for Children, Schools and Families.
"We continue to resolve this particular matter."
A spokesman for the East Riding of Yorkshire Council said: "Arrangements have been made for George to attend school on a full-time basis and his mother has been informed.
"However, she has decided not to send him to school at present.
"The school is following guidance from the local authority and the government in ensuring that George can access his entitlement to education in a safe environment.
"We will continue to work with the family and the school to try to resolve the situation as soon as possible."
