For how long is a Blue Flag displayed after a child has been de-registered?

A Blue Flag is displayed for six months after a child has been de-registered to signify that the child is no longer attending an educational institution. This timeframe is crucial as it allows for a period of monitoring and ensures that any necessary actions regarding the child's educational status or welfare can be taken. It also provides an opportunity for the child to transition to a new educational environment if needed. This duration reflects the practice in educational settings to strike a balance between accountability and support for families.
