This compendium is part of an international project entitled Ethical Research Involving Children. The project has been 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.
