The Program Access Index  is one of the measures FNS uses to reward states for high performance in the administration of SNAP. Performance awards were authorized by the 2022 Farm Bill. The PAI is designed to indicate the degree to which low-income people have access to SNAP benefits. The purpose of this step-by-step guide is to describe the calculation of the PAI in detail. It includes all of the data, adjustments, and calculations used in determining the PAI for every state.
