The purpose of this collaborative workspace is twofold: (1) introduce an ongoing research project on pre-service and novice language teachers’ development of summative assessment literacy funded by the Swedish Research Council (2019-21), and (2) discuss the preliminary results within the context of previous research and relevant theoretical models in order to establish a broader research collaboration for studying the development of summative assessment literacy through pre-service teacher education.  There are different approaches to developing summative assessment literacy such as “assessment for learning” and “assessment of learning,” and it is critical to analyze the impact of these approaches and the respective learning opportunities (courses, seminars, practices, etc.) on pre-service teachers' development of summative assessment literacy.
