Parents should not expect schools to oversee children's food and exercise or toilet attendants, the British school inspector later says.
Ofsted boss Amanda Spielman will argue The response to the obesity crisis is in the home environment, and parents should not "give up responsibility".
Also schools can not be a "panacea" for knife crime or neglect of children, she will add in her second annual report. 1
In February, the British Medical Journal reported that a year-long anti-obesity program involving more than 600 West Midlands elementary students did not bring any improvements.
And in July, Ofsted's study of 60 schools found no link between efforts to combat obesity and student weight.
Late in front of an audience of education and social workers in central London Ms Spielman will point out concerns that at the time elementary school starts, nearly a quarter of the children in England are overweight or obese.
This number increases to more than one third when moving to secondary school.
"Schools can and should teach children about the importance of healthy eating and exercise in harmony with their core purpose, and their physical education should keep them out of breath," she says.
"But beyond that, schools can not take on the role of health professionals – and especially parents."
Recalling the growing evidence that children at the receptionist are unable to use a bathroom she adds, "This is difficult for teachers to interfere with other children and has a terrible social impact on the children involved."
& # 39; Complex matters & # 39;
Ms. Spielman will also argue that society, by expecting schools to tackle gangster crime or childish neglect, not only distracts them from their core purpose, but also does not solve the problems.
Such complex matters must be dealt with by those with the right knowledge and expertise, she will argue.
"While schools can play a role in educating young people about the danger of knives, they can not be a panacea for this particular social disorder," she says.
"Instead, knife criminals have to work together to prevent knife-eating offenses in order to protect children from harm while the relevant authorities tackle criminal activity."
