PISA 2025

From the Headteacher

St Teilo's Church in Wales High School has been selected to participate in the Programme for International Student Assessment (PISA) Study 2025. In receiving a direct link to this update, parents and carers are advised that their Year 11 child will be undertaking the assessment on 1 October 2025.

What is PISA?

PISA is the world’s largest international study of education systems, developed by the Organisation for Economic Cooperation and Development (OECD). Every three years, PISA measures 15-year-olds’ ability to use their reading, mathematics and science knowledge and skills to meet real-life challenges. The PISA 2025 study makes it is possible to evaluate education systems worldwide, by measuring the knowledge and skills of pupils close to the end of compulsory education.

What is involved?

The study will take place within the normal school day and involves your Year 11 child completing a computer-based assessment with multiple choice and open-ended questions in the subjects of reading, mathematics and science, as well as a short questionnaire about their home life, school and interest in subjects, to help us understand how they contribute to academic outcomes. Part of the questionnaire will ask your child about the main job/occupation and education level of any parents/guardians and to write a brief explanation of what the job/occupation involves, so you may want to discuss this with them ahead of time.

Your child doesn’t need to do anything to prepare and participation will not affect your child’s results or progress in school. If there are any questions they do not wish to answer, they may leave them blank. For now, the most important thing is that your child attends school on time on Wednesday 1 October 2025.

What are the benefits?

As a thank you for participating in this important study your child will also receive:

• A personalised certificate from the Welsh Government.
• An exam wellbeing guide for their upcoming exam season.
• 8 'Tempo Time' Credits which can be exchanged for a range of activities at local venues across Wales.

Where can I find more information?

On behalf of the Welsh Government, we would like to thank you and your child for their participation in PISA. Further information is provided below and, as always, you may contact us.
