Desired Distribution of Score Points by Content Category 130. PISA mathematics items are selected to reflect the mathematical content knowledge
described earlier in this framework. The trend items selected for PISA 2021 will be distributed
across the four content categories, as shown in Table 2. The goal in constructing the survey is a
distribution of items with respect to content category that provides as balanced a distribution of
score points as possible, since all of these domains are important for constructive, engaged and
reflective citizens.
