DfE Statutory Guidance makes clear that the Virtual School Head Teacher is the educational advocate for children looked after just as parents are to other children.
Children that are looked after cannot be electively home educated without the agreement of the Local Authority (via the Virtual School Head Teacher) as Corporate Parent for that child.
Local authorities acting as corporate parents of children looked after, should bear in mind that they assume the duties of parents under s.7 of the 1996 Education Act to ensure that the child receives a suitable full-time education; and local authorities in whose areas such children are placed by other authorities should take the same steps to ensure that the child is not missing education as they would for any other child resident in their area.
It is legally possible for a child that is looked after to be educated at home (for example by foster carers) if the local authority as corporate parent decides this is appropriate.
