This is the first book that deals with the reimagination of schools and school systems in international settings. Reimagination should lead to transformation, defined as significant, systematic and sustained change that secures, or has the evidence-based potential to secure, success for all students in all settings through integrated and aligned action in the major domains of school education. Detailed attention is given to Australia, but each chapter contains illustrations from at least two other countries, including the high performers. Australia has gone backwards among nations over several decades despite countless reforms and dramatically increased funding. The prescriptions for reimagination suit all countries where performance falls short of expectations. The book will add value to the work of policymakers at the national and sub-national levels and those who advise them, as well as leaders in school systems and schools. Recommendations will resonate with teachers who feel overwhelmed by what is expected of them. Academics, postgraduate students and other researchers will find fertile ground for their work.
