Authentic assessment has been promoted in teacher education as a means of addressing the challenge that pre-service teachers often face in translating theory into practice. In this article, we outline one approach to authentic assessment that utilises a poster format to present a humanities inquiry sequence. Drawing on a practice-based research project into inquiry learning, we explore the challenges and opportunities of this mode of assessment in meeting our curriculum aims. While we acknowledge limitations in this method, we conclude that posters provide a succinct and engaging means of organising, disseminating and assessing inquiry planning in humanities.
