PISA 2012 is the programme’s 5th survey. It assessed the competencies of 15-year-olds in reading, mathematics and science (with a focus on mathematics) in 65 countries and economies. In 44 of those countries and economies about 85 000 students also took part in an optional assessment of creative problem solving; and in 18 countries and economies, students were assessed in financial literacy.
Around 510 000 students between the ages of 15 years 3 months and 16 years 2 months participated in PISA 2012 as a whole 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.
