The aim of this article is to show how interaction research can contribute to the understanding and praxis of socially just guidance. The article is theoretical, but it makes use of our previous empirical studies. We combine the ethnographic study of school and racism, and interactional research on guidance. We define guidance for social justice, explaining how this translates to the level of interactional practices. We show two empirical examples of interactional phenomena hindering socially just praxis. We lastly discuss our practical conclusions on how to help school career counsellors change their interactional practices.
