This bill directs the Comptroller General of the United States to conduct a comprehensive study on interagency data sharing and collaboration among state agencies administering the WIC, SNAP, and Medicaid programs. The primary objective is to investigate whether such cooperation can lead to increased enrollment in WIC and simplify its certification procedures. The findings of this study are to be submitted to the appropriate Congressional committees within 180 days of the Act's enactment. The study will examine current data sharing practices, including the frequency and existing agreements between state agencies, and assess the overlap in information required for WIC, SNAP, and Medicaid certifications, particularly income data. It will also evaluate the effectiveness of periodic interagency meetings and methods for assessing enrollment gaps or overlaps by comparing participant data. Additionally, the Comptroller General will explore the potential benefits of integrating WIC certification requirements into online eligibility assessments or applications for SNAP or Medicaid, while also analyzing the role of nonprofit organizations in assisting with WIC certification and projecting the costs for states associated with mandatory interagency data sharing.
