Percentage of 15-year-old students scoring higher than 482 but lower than or equal to 545 points on the PISA mathematics scale. At Level 3, students can execute clearly described procedures, including those that require sequential decisions. Their interpretations are sufficiently sound to be a base for building a simple model or for selecting and applying simple problem- solving strategies. Students at this level can interpret and use representations based on different information sources and reason directly from them. They typically show some ability to handle percentages, fractions and decimal numbers, and to work with proportional relationships. Their solutions reflect that they have engaged in basic interpretation and reasoning. Data reflects country performance in the stated year according to PISA reports, but may not be comparable across years or countries.
