Programme for International Student Assessment (PISA)

PISA is an international survey of the performance of students aged 15. It is carried out every three years by the OECD (Organisation for Economic Co-operation and Development) in close collaboration with all the countries taking part in the survey. PISA assesses the skills students have acquired in the fields of written comprehension, mathematics and sciences, which are considered decisive for their further education and adult life.

In 2018, Luxembourg took part in the PISA study for the seventh time. PISA 2018 focused on reading comprehension, i.e. the majority of the exercises concerned this area, with the remainder focusing on mathematics and science. In addition, PISA 2018 assessed attitudes and motivation towards reading as part of a student questionnaire. A total of 79 countries took part in the PISA 2018 study. In Luxembourg, around 5,300 students (born in 2002) from 44 schools, i.e. all secondary schools (public, private and international), participated in a comprehensive survey.

Students could choose German or French as test language, while students in English-speaking sections were tested in English. For the second time in Luxembourg, as was the case in most other countries, students took the PISA tests entirely on computer.

The international results of the PISA 2018 study were published on 3rd December 2019. Luxembourg did not participate in the PISA 2022 study, the results of which were published on 5th December 2023. Luxembourg will again take part in the next PISA study in 2025, which will focus on the natural sciences. The preliminary investigation will take place in all participating countries in 2024.
