Private fostering involves someone other than a parent or close relative becoming responsible for the day-to-day care of a child under tha age of 16 (or 18 if the child has disabilities).
The local authority (LA) must be notified by the parent(s) or private foster carer(s) if this arrangement is intended to last more than 28 days. This is because the relevant LA must be satisfied that the child’s welfare is safeguarded and promoted.
If you’re worried about a child, speak to your DSL (deputy DSL) and follow the school’s procedures for reporting safeguarding concerns.
