Margaret Raymond is the director of the Center for Research in Educational Outcomes (CREDO) at Stanford University, which conducts studies of charter schools, funded by the Walton Family Foundation. On December 10, 2014, she addressed the Cleveland City Club. About 50 minutes (and a few seconds) into a 56-minute talk, she gave the following response to a question about charter school policy:

“This is one of the big insights for me because I actually am a kind of pro-market kind of girl, but the marketplace doesn’t seem to work in a choice environment for education… I’ve studied competitive markets for much of my career… Education is the only industry/sector where the market mechanism just doesn’t work… I think it’s not helpful to expect parents to be the agents of quality assurance throughout the state. There are other supports that are needed… I think we need to have a greater degree of oversight of charter schools, but I also think we need to have more oversight of the overseers… the authorizers.”
