This book discusses principals’ prerequisites and work within the five Nordic countries and focuses on schools as formal institutions that carry out functions delegated to them by the social collective. It includes a discussion about what kind of state policy demonstrates autonomy in Nordic schools, as well as the ways in which school leaders as sense makers in local schools possess and enact policy in a globalized economy and a changing world. The book draws both on a range of theoretical frameworks and educational leadership and policy research to provide multiple comparative perspectives of school leadership in the Nordic countries, the moral purpose of schooling, school governance and power relations, expectations towards school leadership, handling of crises, and cultures of trust. The chapters range from in depth-case studies and policy document analyses to large-scale data sets and literature reviews. All chapters have multiple messages for practitioners, policymakers and researchers as they seek to engage with school leadership as a core activity in times of societal changes. As democratic welfare states, the five Nordic countries have many similarities, but also differences which makes it interesting to understand more about various ways to strive towards democracy and well-educated citizens.
