Under the United Nations Convention on the Rights of the Child all levels of government and anyone delivering public services (including from the voluntary or private sectors) must ensure that the best interests of the child are a primary consideration in all actions concerning children. But no one can know whether this principle is being fulfilled without a child-specific impact assessment and monitoring process in place. The Child Friendly Cities & Communities programme has created a child rights impact assessment (CRIA) template, with accompanying guidance and advice, specifically for local government and partners – offering a standard tool through which to measure the impact of local policies or services on children’s rights.
