US foreign aid agencies have long been at the forefront of evidence-based policymaking—tracking and measuring the impact of assistance programs on well-being and prosperity around the world. As part of the White House Year of Evidence for Action, the White House Office of Science and Technology Policy (OSTP) and the Center for Global Development (CGD), in collaboration with the Office of Management and Budget, invite you to join an Evidence Forum. This event will celebrate progress in advancing evidence use in US foreign aid and explore opportunities for US bilateral aid agencies and their country partners to further elevate and integrate data and analysis in service of better development policy.
