The proposed evaluation will be structured around the ECD program roll out, and will employ a cluster-randomized trial design. For the purposes of the evaluation, a cluster is demarcated by the boundaries of a health zone, a geographic unit defined and used by the Zambia Ministry of Health to determine catchment populations for public health facilities. Each health zone and the children recruited from within the zone comprise a cluster for the trial. The ECD interventions will be implemented in 15 randomly selected health zones across five facilities starting in August 2014. The remaining 15 health zones in the catchments of the five study facilities will continue using current practices and will serve as controls. Within each health zone, a total of around 20 child/caregiver pairs will be recruited and enrolled in the evaluation. In total, the investigators anticipate around 300 child/caregiver pairs being enrolled in each arm of the study, for a total of 600 child/caregiver pairs.
