Promoting teaching, learning and informed decision-making through the lenses of international large-scale assessment: looking beyond numbers

Public discussion on the quality of education in different corners of the world very much relies on the data provided by the international large-scale assessment (ILSA) studies. While aware of different methodological keystones and technicalities embedded in these, the idea behind this special issue is to contribute to the understanding of how students solve ILSA items and the kinds of literacy skills they rely on. A shared element of reported studies is that they seek to document and analyse test-taking as a concrete practice using different theoretical and methodological perspectives. We find such scrutiny to be important and significant at this point in time as it offers some new lenses through which ILSA items could be inspected and further discussed.
