It includes national schematic diagrams, an explanatory guide and a map showing visually the main organisational models of compulsory education. They also reveal that there are three main organisational models of primary and lower secondary education in Europe: Single Structured Education, common core curriculum provision and differentiated lower secondary education. The information is available for 43 European education systems covering 38 countries participating in the EU's Erasmus+ programme. The report's content is in line with the Eurydice Network's task: understand and explain how Europe's different education systems are organised and how they work.
