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.
