Child maltreatment is a complex global problem which remains difficult to study and address. Over the last decade, we have seen considerable interest by governments globally in learning the lessons from different countries and comparing experiences as systems are adapted and refined. International organisations such as the World Health Organization and UNICEF are increasingly prioritising activities to protect children from harm, with important reports on violence against children and strategies for preventing child maltreatment (UNICEF, 2014; World Health Organization, 2002, 2006. In turn, we have begun to see a growing body of literature that has started to provide data and insight into areas such as prevalence rates and developing models of safeguarding as they emerge across an expanding range of countries (e.g. Fang et al., 2015;Hutchinson et al., 2015;Leung et al., 2008;Schmid and Patel, 2016;Sidebotham, 2016).However, the dearth of international literature specifically comparing approaches to safeguarding children demonstrates how challenging it is to undertake research in this field and draw cross-national comparisons of models of child protection (Munro et al., 2011). The difficulty has largely arisen from a lack of common definitions and inconsistency in the way in which child maltreatment is classified, reported, recorded and managed. Yet, we remain interested in this as we also know that the type of model adopted within a country can have a significant impact upon the response subsequently made to children with safeguarding needs. As developing countries look to borrow or import models from overseas, questions are raised concerning cultural adaptation, encompassing the broader debate concerning universalism, indigenisation, the dangers of professional imperialism and the place of international child protection standards.This special issue of Child Abuse Review presents a series of papers which demonstrate how different models of child protection have been developed and implemented in different countries and consider the implications for the treatment and protection of children. It provides examples of cross-national learning and examines the policymaking context behind child protection models and where such learning has not always had positive outcomes for children. The papers cover a range of different approaches or models of child protection. Some of the papers adopt a qualitative approach to explore aspects
