International surveys

Luxembourg participates in various international surveys:

  • Programme for International Student Assessment (PISA);
  • Health Behaviour in School-aged Children (HBSC);
  • International Computer an Information Literacy Study (ICILS).

Programme for International Student Assessment (PISA)

PISA is an international survey of the performance of students aged 15. It is carried out every 3 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 sciences, mathematics and written comprehension, which are considered decisive for the continuation of their education and their adult life.

Health Behaviour in School-aged Children (HBSC)

The international Health Behaviour in School-aged Children (HBSC) study investigates the well-being and lifestyle habits of children and adolescents aged 11 to 18. It is under the patronage of the World Health Organisation (WHO) and is carried out every four years in over 50 countries using a standardised questionnaire, which young people fill in at school.

The main aims of the HBSC study are:

  • to assess the well-being, physical and mental health as well as health-related behaviours of young people;
  • to identify the factors that have an impact on young people’s health and well-being.

Luxembourg carried out a pilot study for the first time in 1999 and has participated regularly in HBSC surveys since 2006. The studies are carried out in collaboration with various partners, the Ministry of Health, the Ministry of Education, Children and Youth and the University of Luxembourg, the latter being responsible for the scientific supervision of the study.

International Computer and Information Literacy Study (ICILS)

In 2023, Luxembourg took part for the second time in the International Computer and Information Literacy Study (ICILS). This study aims to analyse how young people use computers to study, create and communicate in order to participate effectively at home, at school, in the workplace and in society.

All 6e classes in secondary education in Luxembourg took part in the survey in April/May 2023. The publication of the international report is scheduled for the end of 2025.
