This form will help to track children that have gone through the BID process. More detailed guidelines with related forms for each step of the process are available in the UNHCR Best Interest Determination Guidelines (See Tool 14). Tool 25 is part of the tools and guidance in the ACE Toolkit designed to facilitate the process of planning for and implementing interim care and related services for children separated from or unable to live with their families during an emergency. The Toolkit includes the following 3 resources: Summary Guidance, Extended Guidance, and a range of tools to assist in the implementation of quality care.
