The United Nations Convention on the Rights of the Child states that interventions must be in the best interests of the child (article 3), they should facilitate the return of children to their families (articles 8-10) and all placements must protect children and be subject to periodic reviews (articles 20 & 25). All child care and protection workers should have the tools and knowledge to adequately assess how to support a child. This includes knowledge on the effects of institutional care and child development information.
