This Ethical Research Involving Children (ERIC project) is an international project motivated by a shared international concern that the human dignity of children is honoured, and that their rights and well-being are respected in all research, regardless of context. To help meet this aim, the compendium acts as a tool to generate critical thinking, reflective dialogue and ethical decision-making, and to contribute to improved research practice with children across different disciplines, theoretical and methodological standpoints, and international contexts. Emphasis is placed on the need for a reflexive approach to research ethics that fosters dynamic, respectful relationships between researchers, children, families, communities, research organizations, and other stakeholders. Hence, the content of this ERIC compendium moves beyond prescriptive approaches to encourage a more critical engagement with ethical issues and contemporary research practices across the multiple sectors and national/international contexts in which these take place. ERIC has been developed to support all researchers, individuals and organizations who are involved in research that is undertaken with, or potentially impacts on, children. This includes researchers, all members of any research team, research organizations, other stakeholders and research ethics review committees.
