Eric Hanushek is the Paul and Jean Hanna Senior Fellow at the Hoover Institution of Stanford University. He has been a leader in the development of economic analysis of educational issues. He has authored numerous, highly cited studies on the effects of class size reduction, high stakes accountability, value-added assessments of teacher quality, and other education related topics. His pioneering analysis measuring teacher quality through the growth in student achievement forms the basis for current research into the value-added of teachers and schools. Most recently, Hanushek shows that the quality of education is closely related to national economic growth.
