This book includes StatLinks, urls linking to Excel® spreadsheets containing the background data.'

Covering selected topics from early childhood education to adult education, the reports aim to provide a comparative understanding of how priorities and policies are evolving, and how policies can be best implemented or improved over time in their specific contexts.’
