This report demonstrates how existing national data can be used to first calculate upper limits on the average cost per participant and per outcome per state/territory for the Expanded Food and Nutrition Education Program (EFNEP). These upper limits can then be used by state EFNEP administrators to obtain more precise estimates for their states, based on their state-specific knowledge. Across all states, EFNEP appears most cost effective in nutrition practices, followed by food resource management practices, and then food safety practices. All but 3 states have cost per quality adjusted life years that are considered cost effective. (Contains 2 tables and 2 figures.)
