The focus of PISA 2015 was science. To understand more about the PISA 2015 science assessments, see the sample questions on the OECD website. You can also explore the concepts and competencies being investigated and learn what 15-year-old pupils at different proficiency levels can do.
All students and schools complete questionnaires. Some questions which were included in previous PISA studies allow comparisons over time, and new questions allow us to better understand students' and teachers' experiences of the subject focus (maths is the focus for PISA 2021). The following links are examples of the student and school questionnaires.
There are additional questionnaires which countries can choose to participate in. Pupils in Scotland will be asked about their familiarity with ICT.
