Using data from a case-study school as a springboard, this article explores how enactments of democratic education might both problematise and illuminate new possibilities for the way we conceptualise social justice in education. Nancy Fraser's tripartite framework of social justice is used to analyse in-depth interviews with students aged 14-16 from a democratic school in the United Kingdom. The article makes two key arguments: first, it highlights the interdependence of 'recognition' and 'representation' and, consequently, calls on mainstream policy and practice to make a substantive commitment to participatory democracy as part of the 'inclusive education' agenda. Second, it points to the tensions between 'redistributive' justice and other social justice aims which may be particularly stark in democratic education (and other progressive education) spaces. The article suggests that a strengthened relationship between democratic schools and research communities would offer a crucial contribution to collective critical reflection on social justice in education.
