Extension professionals face challenges in quantifying the impact of their efforts in advancing the decision-making process inherent in setting natural resources policy. We developed a flexible tool that measures the impact of improving decision makers' planning efforts. The tool consists of two sets of survey questions that can be modified to fit an Extension program's goals. We illustrated how to use the tool by surveying leaders working with private forest owners to advance natural resources management. However, the tool can be of use to Extension professionals across various program areas.
