NATIONAL QUESTIONS – DATA SET

Countries participating in International Large-Scale Assessments may – in agreement with the organizers – include a small number of questions in the questionnaire that are of particular national relevance. These items are usually placed at the end of the questionnaire. Datasets are provided below with respondents’ answers to the country-specific questions from the most recent cycle (ICCS 2022). The files can be merged with the publicly available international databases by using the common identifier (student ID).
