Lawmakers in Congress have expressed a growing interest in the promise of evidence-based policymaking. Bipartisan legislation has been pursued in Congress that would encourage the use of evidence to improve outcomes for key education, health, workforce, and other federal programs. These past legislative initiatives suggest growing potential for the wider use of evidence to better inform congressional decision-making in the future. However, key challenges remain for fostering a stronger culture of evidence in Congress. This stronger culture will be necessary to fully realize the potential benefits of evidence-based policymaking.
