This comparative analysis is based on country descriptions supplied by the Eurydice National Units.
To collect information for them, a Guide to Content, including common guidelines and definitions, was prepared by the Eurydice European Unit (EEU) in consultation with the National Units at the beginning of 2004.
The aim of the Guide to Content was to ensure that the country descriptions were drafted in accordance with a common structure to facilitate subsequent cross-country comparison of the information provided.
