The NRC surveys charitable entities in the U.S. and Canada. Members agree to combine survey questions to fit on one of the two annual NRC surveys. Collaborative members provide and review the survey questions, develop a list of constituents to be surveyed, and publicize the survey and results. They also provide guidance on additional research topics, interpret results, and offer recommendations for how to implement study findings.
