CREDO is a key source to help policymakers and educators on the ground make difficult decisions based on sound data and research.  It serves as a viral source for improving the state of education research by driving for better, more transparent and actionable data, such that its research can continue to shine a brighter and brighter light on what is and isn’t working for students. It’s also the rare trusted source where the research doesn’t have an agenda. The team follows what the data says and presents it fairly and without varnish.
