CREDO at Stanford University produces rigorous, non-partisan research and evaluation to enhance the body of empirical evidence, driving education policy decisions toward improved education outcomes for all students. Established at the University of Rochester in 1999 and relocated to Stanford University one year later, CREDO has become a leading independent voice in the discussion of how to improve education in America, with an emphasis on rigorous program and policy analysis as the means of informing and improving education decision making. Our primary aim at CREDO is to support educators and policymakers in using the insights that come from sound research to shape program and policy development. We focus on asking the right questions and delivering statistically sound answers as the basis for assessing the effectiveness of education initiatives. We also work to align expectations among key groups around how a quality school performs and how different stakeholders can work together to ensure accountability and academic excellence.
