In this article, we contribute to a discussion of ethics within school bullying research by reflecting on our own recent ethnographic study into the relations between school bullying and the institutional context of schooling conducted at three elementary schools and one lower-secondary school in Sweden. We argue for a reflexive, responsive, and flexible adult researcher role when conducting ethnographic research into school bullying; what we term the caring adult role. The caring adult role provides a means of ethically conducting research by helping to facilitate access, navigate power relations, provide a consistent starting point for deciding when to intervene in ethically questionable situations, and a way for adult researchers to differentiate themselves from those adults in schools who may be perceived by students as non-caring. We argue that this is an ethically sounder approach than one that suspends all adult-like characteristics and avoids directing or correcting the behaviour of children.
