This section provides the most recent available data on the number of educational institutions from pre-primary to post-secondary non-tertiary education level (ISCED levels 0-4). Statistics on numbers and characteristics of higher education institutions can be found in the European Tertiary Education Register. A general overview of the categories of institutions providing publicly-subsidised adult education and training can be found in the chapter on adult education. The notes below the tables provide methodological explanations necessary for a good interpretation of data.
