This paper analyzes and discusses possibilities and challenges for teachers to use collegial mutual deliberation as a way to counteract racism. A starting point is taken from research on teacher collaboration that has emphasized the importance to locally create conditions for critical discussions that exceed coherence and simple solutions. To do this, we turn to the idea on deliberative communication, which in the paper fills two purposes: First, as a means for a teacher who, supported by us as researchers, leads a discussion about racism with colleagues, and secondly, as a theoretical lens to analyze that same discussion. The study provides theoretical and empirical knowledge about how collegial deliberation potentially can contribute to the development of a communicative teacher community.
