This fact sheet provides a brief overview of how the Child Status Index (CSI) can be used by community health works to monitor the wellbeing of orphans and vulnerable children (OVC). The CSI measures six broad areas of a child's wellbeing: food and nutrition; shelter and care; protecting health; psychosocial; protection; and education and skills. The CSI is designed so that measurement can be performed by people living in the same communities as the affected children, who are in the best position to monitor the health of those children on a regular basis.
