PISA 2012 is program's 5th survey which assessed the competencies of 15-year-olds in reading, mathematics and science (with a focus on mathematics) in 65 countries. Around 510 000 students between the ages of 15 years 3 months and 16 years 2 months participated in the assessment, representing about 28 million 15-year-olds globally.
The students took a paper-based test that lasted 2 hours. The tests were a mixture of open-ended and multiple-choice questions that were organised in groups based on a passage setting out a real-life situation. A total of about 390 minutes of test items were covered. Students took different combinations of different tests. They and their school principals also answered questionnaires to provide information about the students' backgrounds, schools and learning experiences and about the broader school system and learning environment.
The results are the following (#).
- . Girls perform better than boys with a statistically significant difference of 40 points (OECD average: 38 points higher for girls).
- On average, . Girls perform better than boys with a statistically significant difference of 2 points (OECD average: 11 points higher for boys).
- . Girls perform better than boys with a non statistically significant difference of 6 points (OECD average: only 1 point higher for boys).
