Age Assessments
About Age Assessments
The age of an unaccompanied child is important. It determines a child’s access to education and support, effects the way in which their asylum claim is processed and can even be a decisive factor in a claim for asylum. If a child or young person’s age is disputed, an age assessment should be conducted.
Coram Children’s Legal Centre has a great resource detailing the age assessment process, which is linked via the button below.
Young people with lived experience of age assessments have been working with Greater Manchester Immigration Aid Unit (GMIAU) and Refugee Council on a new Age Disputes Toolkit. It includes an updated Young People’s Guide to Age Assessments and a Practitioners Toolkit.
Facial Age Estimation (FAE) Tool
The Home Office are exploring the possibility of introducing a Facial Age Estimation (FAE) tool to support initial age decisions. Information can be found on the Gov UK website. The tool uses machine learning technology to estimate an individual’s age within seconds by analysing a facial photograph without further information about the individual.
The Home Office has been clear that FAE would be used only as a supplementary tool for immigration officers, providing additional information to help them make initial age decisions. It won’t be relied upon to make a definitive age decision or to replace holistic approaches such as Merton-compliant age assessments.
