Percentage of 15-year-old students below the lowest proficiency level (scoring 358 or below) on the PISA mathematics scale. Students below Level 1 may be able to perform very direct and straightforward mathematical tasks, such as reading a single value from a well-labeled chart or table where the labels on the chart match the words in the stimulus and question, so that the selection criteria are clear and the relationship between the chart and the aspects of the context depicted are evident, and performing arithmetic calculations with whole numbers by following clear and well-defined instructions. Data reflects country performance in the stated year according to PISA reports, but may not be comparable across years or countries.
