One common argument against charter schools is that, even if they do score better on math and reading tests than traditional public schools (TPS), it’s only because they enroll far fewer special needs students, poor students, or students who are learning English as a second language.
We can see if this claim is true or not thanks to Stanford’s Center for Research on Education Outcomes (CREDO), which has a nifty-difty chart in its 2015 report on urban charter schools that compares the percent of students who fit the above criteria in charters and traditional schools across 41 urban regions.
