PISA 2022 in Switzerland, add-on to the international dataset: Swiss specific variables

Since 2000, Switzerland participated in every PISA cycle conducted by the OECD. At the end of every cycle, the Swiss PISA data of the national 15-year-old sample has been made available in the international data sets published on the OECD website.

Before 2015, in addition to the sample of the 15-year-olds, an additional and larger sample of 9th grade students was drawn and tested in Switzerland. The resulting Swiss data for the 9th grade students, that allowed comparisons selected cantons, was published in full on FORSbase, now SwissUbase. Since 2015, solely the national PISA sample from the population of 15-year-olds is tested, that allows comparisons between three Swiss language regions, but not anymore between selected cantons.
