Foreword and Acknowledgements

One of the crucial issues for OECD countries is how to deliver high quality, efficient, equitable and innovative education in increasingly complex education systems. A number of intersecting trends contribute to this increasing complexity: decentralisation has allowed local authorities, school boards and schools a greater degree of freedom to respond to local demands. Parents in OECD countries have become more diverse, individualistic and highly educated. With more readily available evidence about school and student achievement, stakeholders have also become more demanding towards schools to cater to students’ individual needs. Education systems are now characterised by multi-level governance where the links between multiple actors operating at different levels are to a certain extent fluid and open to negotiation.
