As part of the “Bildung in Zahlen” (Education by numbers) project funded by the Swiss National Science Foundation, long-term statistical series on the development of cantonal education programmes and the vocational education and training system in Switzerland in the 19th and 20th centuries were being generated, annotated and contextualised between September 2010 and December 2023. The research infrastructure comprises data on all educational levels, including pre-school, compulsory school, secondary school, higher education as well as vocational and professional education and training. The statistical data provide a basis for empirical-quantitative and historical analysis of changes in education systems in Switzerland. In addition, information on the sources used to compile these series, graphs visualizing school types and educational pathways as well as chronicles containing information on normative changes in school structures allow the statistical data to be placed in the historical context of the respective (cantonal) education system.
