Underachievement in reading (i28)

Definition: the indicator measures the proportion of 15-year-old students who do not reach level 2 (elementary level) of the PISA scale for reading performance. It is one of the three key areas of learning, alongside mathematics and sciences. The data come from the Programme for International Student Assessment (PISA), an international survey conducted every three years to assess the skills and knowledge of 15-year-old students. In Belgium, the tests are carried out by the universities of Ghent and Liege. Since these data are based on surveys, a margin of uncertainty should be taken into account. The confidence intervals can be found on the OECD website, on the PISA data pages.
