Resource | Research and Data | Food Security WIC Infant and Toddler Feeding Practices Study 2 (ITFPS-2): Third Year Report

The WIC Infant and Toddler Feeding Practices Study 2 (WIC ITFPS-2)/ “Feeding My Baby” Study  captures data on caregivers and their children over the first 6 years of the child’s life after WIC enrollment to address a series of research questions regarding feeding practices, associations between WIC services and those practices, and the health and nutrition outcomes of children receiving WIC. To date, the study has produced three reports: the Intentions to Breastfeed Report (2015); the Infant Year Report (2017); and the Second Year Report (2018). The current report focuses on caregivers’ employment, school, and child care circumstances, as well as the feeding beliefs and practices, dietary intake, and weight status of children from birth through approximately 36 months of age.

Resource | Research and Data | Assessing/Improving Operations CACFP Sponsor Tiering Determination Aging Study, 2015 - 2020

This report describes the feasibility of a modeling approach to forecast tiering error rates based on prior data, in lieu of annual assessments of misclassified FDCHs. It presents estimates for forecasted rates and associated improper payments for FDCHs for each fiscal year (FY) from 2016 to 2020. Due to data limitations, the report concludes that building a reliable model is not possible with the currently available data and estimates produced by the models cannot be used for IPERIA reporting.
