Two new documents from the Scottish Government and the Centre for Excellence for Looked After Children in Scotland (CELCIS) aim to help staff put policy into practice.
The duties of councils and other agencies as 'corporate parents' to children who can no longer stay at home with their natural families, are set out in policies such as We Can and Must Do Better and These Are Our Bairns.
But the new guidance aims to underpin the policies with principles which corporate parents should adopt. Staying Put Scotnlad and Housing Options, suggest housing and social work staff should be better trained to understand what would help care leavers.
CELCIS Director Jennifer Davidson said: "There is a real frustration among managers and practitioners around the age that young people leave care. In many cases it is simply too young and too sudden, and the expectations we place on care leavers is unrealistic and unfair."
