In this paper, we undertake a content analysis of mathematics assessment tasks to understand how often graphical representations are embedded within high-stakes national and international tests. A total of 274 items were analysed, consisting of 160 Grade 9 UN items, 88 Grade 8 TIMSS items, and 26 PISA items. Analysis showed that all items in the PISA test were embedded with graphics, with far fewer graphical items in the TIMMS and national UN tests (47% and 33% respectively). We also found that graphical items in UN tests are distinct from PISA and TIMSS, suggesting a misalignment between what is represented in UN tests and international instruments.
