This document introduces the Child Status Index (CSI), a tool developed to monitor outcomes for orphaned and vulnerable children (OVC) receiving support programs in sub-Saharan Africa. The CSI was created through participatory research with local communities to assess child well-being across 12 domains, including food, shelter, health, education and psychosocial support. It provides a standardized way for programs to evaluate how services are impacting children and to match children's needs with available support. The CSI is being implemented by various NGOs and national monitoring systems to improve outcomes for OVC.
