High quality evidence is fundamental for decisions to improve public well-being. For policymakers, philanthropies, practitioners, and others concerned with evidence-based decision making, the Center for Improving Research Evidence (CIRE) provides training and assistance in designing, conducting, assessing, and using a range of scientific policy research and evaluations in worldwide settings. CIRE develops and shares methods and standards for data collection, research, and evaluation, and applies these standards to assess the strength of existing evidence.
