This article focuses on the merits and challenges of using qualitative research methods, and how these can contribute positively to the study of assessment. Based on a presentation from a methods-related research seminar, this paper appeals for research engagement with those areas where assessment affects the lives of others. This appeal means not only asking the difficult questions but also having the appropriate methodologies to try to answer them. The paper goes on to champion the strengths of mixed methods approaches that allow for triangulation, complementarity (where findings gained through one method offer insights into other findings) and expansion (of the breadth and scope of the research beyond initial findings).
