The Summer Electronic Benefits Transfer for Children (SEBTC) demonstration uses the SNAP and WIC EBT systems to deliver benefits to children during summer months. The evaluation examined the impact of a $30 per child per month benefit on child, adult and household food security relative to a $60 monthly benefit. It found that the $30 benefit was as effective in reducing the most severe category of food insecurity among children during the summer as the $60 benefit. However, the $30 benefit was only about half as effective as the $60 benefit at reducing the less severe but more prevalent food security among children. Results were similar across SNAP and WIC sites.
