The same Stanford researcher conducted an RCT of charter schools in Chicago and found: “students in charter schools outperformed a comparable group of lotteried-out students who remained in regular Chicago public schools by 5 to 6 percentile points in math and about 5 percentile points in reading…. To put the gains in perspective, it may help to know that 5 to 6 percentile points is just under half of the gap between the average disadvantaged, minority student in Chicago public schools and the average middle-income, nonminority student in a suburban district.” And the last RCT was a national study conducted by researchers at Mathematica for the US Department of Education. It found significant gains for disadvantaged students in charter schools but the opposite for wealthy suburban students in charter schools. They could not determine why the benefits of charters were found only in urban, disadvantaged settings, but their findings are consistent with the three other RCTs that found significant achievement gains for charter students in Boston, Chicago, and New York City.
