WIC, or the Special Supplemental Nutrition Program for Women, Infants, and Children, helps to meet the nutrition needs of pregnant, postpartum, and breastfeeding women, and their children under the age of five, who live on low incomes by providing monthly
benefits that are used to purchase healthy foods. In 2019, a subgroup of the HER NOPREN WIC Learning Collaborative and liaisons from the National WIC Association
convened under the leadership of UD CRESP to develop a protocol for describing and comparing vendor criteria and policies across WIC administrative agencies. This brief provides the results of an analysis of WIC vendor selection and authorization criteria, and operations and management policies established by the 89 administrative agencies
in the United States. Full details and findings are reported elsewhere (Landry et al., 2021).
