This report presents findings and insights generated through a mapping and assessment of 6 state child protection systems in Nigeria. The process began in September 2013 and was completed in 2014. The goal of the mapping was to provide State actors with a profile of existing child protection systems and to provide recommendations to remedy existing gaps as revealed through the mapping exercise. This report serves as a guide towards strengthening the existing formal and informal child protection components (including the social service workforce), functions and local context. More so, it serves as a relevant reference for future interventions and as a mechanism to promote better coordination among partners to optimize their support for quality service delivery for vulnerable children.
