Numeracy

In PIAAC, numeracy is defined as the ability to access, use, interpret, and communicate mathematical information. The assessment of numeracy focuses on the extent to which respondents are able to master everyday mathematical tasks such as, for example, the evaluation of a special offer or the interpretation of numerical information in graphs and tables. Like reading literacy, numeracy is a prerequisite for developing higher-order skills.
