This special issue focuses on important facets of market-oriented reforms in Nordic Early Childhood Education and Care (ECEC). It aims to promote discussion on interlinked dimensions of marketisation, privatisation and commercialisation in Nordic ECEC and their manifestations in policy, practice and outcomes. With contributions from authors in five Nordic countries, the articles in the special issue offer accounts of marketisation, including the organisation of ECEC quasi-markets and shifts in the use and function of parental choice. The articles also analyse privatisation by researching the delivery of private services and the nature of the non-state providers within early childhood education markets. Finally, the theme of commercialisation is addressed through research on the commodification of preschool knowledge within Nordic countries but also its export in the global education industry. This special issue highlight how a variety of market-oriented policies, parental choice and private actor involvement are evolving. Taken together, the articles illustrate connections and mutually-reinforcing mechanisms of policy and practice that contribute to the expansion of marketisation, privatisation, and commercialisation in Nordic ECEC. This special issue provides a call to continue exploration of how these processes and actors contribute to the transformation of ECEC in the Nordic countries and elsewhere.
