Trey Miller is an associate economist at the RAND Corporation, where he specializes in U.S. and international education policy. Miller has advised government agencies in the United States and abroad on how to develop, maintain, and use complex data systems to efficiently evaluate the effectiveness of higher education systems, institutions, programs, and policies. He employs education databases and uses experimental and quasi-experimental methods such as regression discontinuity, instrumental variables methods, and propensity score matching methods to evaluate the causal impact of education programs and policies. Miller was the principal investigator (PI) for a study funded by the Gates Foundation that used administrative databases to develop value-added measures for the higher education sector. He also worked with the Abu Dhabi Education Council to develop a set of quantitative and qualitative indicators to assess the performance of higher education institutions. He was a co-PI for a research project funded by the Spencer Foundation to assess the impact of policies governing college tuition towards undocumented immigrants on educational attainment of the undocumented. He recently helped design, implement, and analyze a random controlled trial experiment in Pittsburgh to evaluate the impact of student and parent incentives to attend a voluntary summer learning program on student attendance patterns and learning outcomes. Currently, he is analyzing proposals for higher education policy set forth in India's 12th Five-Year Plan and developing a set of recommendations for implementation. Miller earned his Ph.D. in economics from Stanford University.
