This paper aims to reflect upon ethical dilemmas arising from educational research in humanitarian contexts, particularly when involving children. In recognition of the paucity of knowledge on how to define ethics in humanitarian research, we review the existing body of literature that explores ethical responsibilities towards children involved in educational research at school and their communities. The paper argues that research ethics should be at the forefront of every study that is conducted in crisis contexts and more rigorous review and vetting processes are necessary to protect children, researchers and wider communities who live in crisis settings. We hope to promote an informed debate on research ethics in humanitarian contexts, while encouraging the development of rigorous guidelines, notes and minimum standards.
