Inquiry learning is an educational approach that involves a process of exploration, asking questions and making discoveries in the search for new understandings. Researchers however are divided about the value of the approach. In the symposium, it is argued that one of the reasons for this controversy is the way that inquiry learning is assessed. Consequently, we aim to present papers which reflect on the challenge of assessing inquiry learning by describing the prevailing approaches to assessment and how technological and theoretical advancement is changing these approaches. The aim is not just to describe these approaches but reflect upon the opportunities that are created and difficulties that must be overcome as we pursue the goal of assessing the processes and outcomes of inquiry learning
