This chapter argues that there is a gap in current research in Philosophy for/with Children (P4wC) that focusses on teachers' perspectives, and particularly in relation to their beliefs and values. This chapter will look briefly the current status of P4wC in the sphere of education broadly. It will then move on to exploring how teachers' perspectives, through analyses of their beliefs and values, adds significant value in education. This chapter then explores the importance of teachers' beliefs and values specifically in the context of P4wC, identifying the contribution that an analysis of teacher beliefs and values can make. It then concludes by analysing some recent P4wC research which has begun to explore teachers' perspectives, before finishing with future research directions that build on these previous studies which will lay important groundwork for extending the reach of P4wC into education systems.
