"Priority for 'previously looked after' children
The new School Admissions Code (released in February 2012) introduced a new requirement on all admission authorities to broaden the existing priority for 'looked after children' or children in care, in accordance with section 22 of the Children Act 1989, to also include 'previously looked after' children, for 2013 admissions onwards.
Children who were 'previously looked after' are defined for the purposes of the legislation as those who immediately after being in care became subject to an adoption, residence, or special guardianship order.
Required Evidence for a 'previously looked after' child
an adoption order under section 46 of the Adoption and Children act 2002; or
a residence order settling the arrangements to be made as to the person with whom the child is to live under section 8 of the Children Act 1998; or
a special guardianship order appointing one or more individuals to be a child's special guardian(s), under section 14A of the Children Act 1989."
The name of the social worker has to be given on the application, etc.
So, for example, babies adopted straight from the birth family wouldn't qualify. Children adopted from care have generally been with foster parents and may have experienced neglect or worse, may have attachment disorders which require support and intervention and a particular environment.
