«Compared to students in the nearest regular public school with
a similar racial composition, charter students are 5 percent more likely to be proficient in reading and 3 percent more likely to be proficient in math.
Those sentiments were captured in another study by Harvard economics professor Caroline M. Hoxby, who compared the math and reading proficiency of almost all the nation's charter school students to the test results of those at their nearest public school with
similar racial composition.
Hoxby quickly gathered data, and just a month after the AFT study grabbed headlines, her study, A Straightforward Comparison of Charter Schools and Regular Public Schools in the United States, is making news with findings showing that, on average, students in charter schools are 5 percent more likely to be proficient in reading and 3 percent more likely to be proficient in math than students at the closest public schools with
similar racial composition.
The paper demonstrates this point by showing that in the aggregate, a comparison of racial composition of sending and receiving schools shows no large differences — it appears that students are switching to schools of
similar racial composition.
However, a RAND study found that, in most states, students tend to transfer between traditional public and charter schools with
similar racial compositions.

similar to that of the traditional public school that he or she had left.
Clearly, the takeaway message from the RAND study — as the authors explicitly state — is that students who transfer into charters in these cities attend schools with
racial compositions that are
similar to the TPS attended in the prior year.
