This is the first study to provide a comprehensive account of the WIC nutrition assessment and tailoring process. The nutrition and breastfeeding assessment process is critical to the delivery of individualized nutrition services and to meeting WIC’s mission. Study findings will inform FNS and WIC state and local agencies about how to enhance service delivery and improve retention of WIC participants.

This analysis helps to estimate the nutritional quality of the 2022 FDPIR food package 'as offered' using the Healthy Eating Index scoring algorithm. This will provide an update to the first HEI estimate of the 2014 FDPIR food package. The project also aims to estimate the HEIs of the food packages 'as delivered' to participants.
