SNAP Education (SNAP-Ed) is the nutrition education and obesity prevention component of SNAP; its goal is to improve the likelihood that persons eligible for SNAP will make nutritious food choices within a limited budget and choose physically active lifestyles consistent with the current Dietary Guidelines for Americans and the USDA food guidance.

The Special Nutrition Program Operations Study is a multiyear study designed to provide the Food and Nutrition Service with a snapshot of current state and school food authority policies and practices of the school meal programs, including information on school meal standards, competitive foods standards, professional standards, school lunch pricing and accounting, and Smarter Lunchrooms activities. 

FNS asked Mathematica Policy Research, Inc., (MPR) to assess the CPS estimates in relation to alternative estimates from the Survey of Income and Program Participation (SIPP), which collects longitudinal monthly income data.
