The impact of a nutrition-sensitive graduation model on child nutrition: Experimental evidence from Ethiopia

This brief reports on a three-arm cluster randomized controlled trial of 3,015 households evaluating the effectiveness of SPIR II, a nutrition-sensitive graduation model implemented in Ethiopia. The full treatment package—combining nutrition-focused behavior change communication (BCC), village economics and savings associations, monthly maternal cash transfers of US$20, and a one-time livelihood grant of US$300—generates large, sustained improvements in child diet quality, household consumption, livestock holdings, and formal savings. A substantial reduction in childhood stunting (7 percentage points) is observed in the same sub-arm; BCC alone improves caregiver nutrition knowledge but does not lead to improved child feeding or growth. The benefit-cost ratio is nearly two, suggesting the program more than pays for itself.

Can simpler, cheaper graduation programmes still deliver?

Can simpler, cheaper graduation programmes still deliver?

A randomised evaluation of a lower-cost graduation-style programme in rural Ethiopia finds modest gains in savings and livestock income but no sustained improvements in consumption or food security, suggesting that smaller transfers and lighter support may be insufficient to help extremely poor households escape poverty, particularly in shock-prone settings.
