OK Preschool Study Provides No Evidence of Lasting Benefits from Preschool | Cato @ Liberty: "There is little evidence in the research that these kinds of preschool programs impart lasting gains to low-income students and no evidence that they benefit middle-class kids. The real-world evidence demonstrates that the test scores of children in Oklahoma have eroded significantly, as have our nation’s performance on international tests, at the same time that preschool programs have massively expanded and the quality of those programs has supposedly improved."
