This profile builds on the knowledge and expertise of many project teams across the OECD's Directorate for Education and Skills, to whom we are grateful. Much of this information and documentation can be accessed through the Education GPS http://apseducation.oecd.org. Hyperlinks to the reference publications and to relevant legislation are included throughout the text for ease of reading, and also in the References and further reading section, which lists both OECD and non-OECD sources.
