Through the method of tracing-and-mapping, this paper traces the history of how menstruation has been conceptualized in English education policies since 1928, as well as how such conceptualizations have positioned young people. It explains how education policy in England has conceptualized menstruation as a (cis girls') biological process; a controllable problem; and a process that can be instructed on and learned. The paper unfolds how such conceptualizations positioned young people as passive non-agents. It also draws on feminist relational materialism, critical menstruation studies and childhood studies to experiment with different articulations of menstruation and agency. It concludes by reimagining menstruation education and young people's role in addressing menstrual stigma.
