Resource | Research and Data Development of a WIC Participant and Program Characteristics Longitudinal Data Set

The goal of this study was to pilot creating a WIC participant characteristics (PC) longitudinal data set with one WIC state agency. Eight state agencies with varying management information systems (MIS) platforms and high quality WIC PC 2020 data completed a survey about their MIS and longitudinal data provision capabilities. The survey assessed these state agencies’ MIS capabilities, as measured in six areas, to provide a longitudinal data set. This report describes the process of working with one WIC state agency to create a pilot WIC PC longitudinal data set of infant and child participants and the challenges and successes of this effort.

Resource | Research and Data | Benefit Content/Cost WIC Participant and Program Characteristics 2016 Food Package Report

The biennial WIC Participant and Program Characteristics Report describes a census of all participants in WIC. The most recent report (PC 2016) reflects state management information systems data from April 2016, and this Food Package Report is a supplemental analysis of that data. While PC 2016 summarizes participant characteristics, this report summarizes the food packages, or prescriptions, that state agencies issued to these participants.

Resource | Research and Data | Assessing/Improving Operations Approaches to Measuring Erroneous Payments in the National School Lunch Program and School Breakfast Program At The State Level

The second Access, Participation, Eligibility and Certification Study (APEC II) included a follow-on report that provided statistically-derived state-level estimates of school meals erroneous payments. However, while APEC II provided a rough indicator of relative risk for groups of states (e.g., higher than average, about average, lower than average), it was not a state-representative direct measure, and creating actual annual measures of such erroneous payments at the state level using APEC methodology is cost-prohibitive. This report explores alternative approaches to developing measurement-based state-specific estimates that are responsive to year-to-year changes in the actual underlying rate in each state. It also provides cost and burden estimates for the implementation of each of these methods.
