Book excerpt: This book is a response to the loss of learning experienced by children and young people during the Covid-19 crisis. It examines the measures which were taken to fix the disruption of education and their limitations particularly in reaching marginalised groups. Drawing on data and experiences from around the world, the book examines education systems as ecosystems with interdependencies between many different components which need to be considered when change is contemplated. Chapters explore the challenges involved ensuring continuity of education for all learners in times of crisis and disruption and set out practical solutions that are relevant when preparing for natural disasters and disasters caused by humans as well as for climate change challenges and future pandemics. The focus throughout is on building the sustainability of learners’ education into education systems to ensure educational continuity for all learners in times of disruption and crisis. Including tools for planning, prompts for reflection, and future possibilities to consider, Education for All in Times of Crisis will be valuable reading for school leaders, educators and policy makers.
