Using Mathematical Competencies to Predict Item Difficulty in PISA: A MEG Study

This paper reports an analysis of features of mathematics assessment items developed for the OECD’s Programme for International Student Assessment survey (PISA) in relation to a set of six mathematical competencies. These competencies have underpinned the PISA mathematics framework since the inception of the PISA survey; they have been used to drive mathematics curriculum and assessment review and reform in several countries; and the results of the study are therefore likely to be of interest to the broad mathematics education community.
