The Participant Access Rate (PAR) is one of the measures FNS uses to reward States for high performance in the administration of the Food Stamp Program. Performance awards were authorized by the Farm Security and Rural Investment Act of 2002 (also known as the Farm Bill). The PAR is designed to indicate the degree to which low-income people have access to food stamp benefits. The purpose of this step-by-step guide is to describe the calculation of the PAR in detail. It includes all of the data, adjustments, and calculations used in determining the PAR for every State in 2003.
