Last month there was a kerfuffle when the New York Times splashed a shoddy American Federation of Teachers study suggesting charter schools were a buit on their front page. Click here for the roundup. This month, EduWonk’s Andy Rotherham alerts us to a more sophisticated study by Harvard economist Caroline M. Hoxby. This is the abstract:

This study compares the reading and mathematics proficiency of charter school students to that of their fellow students in neighboring public schools. Unlike previous studies, which include only a tiny fraction (3 percent) of charter school students, this study covers 99 percent of such students. The charter schools are compared to the schools that their students would most likely otherwise attend: the nearest regular public school and the nearest regular public school with a similar racial composition. In most cases, the two comparison schools are one and the same. Compared to students in the nearest regular public school, charter students are 4 percent more likely to be proficient in reading and 2 percent more likely to be proficient in math, on their state’s exams. 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. In states where charter schools are well-established, charter school students’ proficiency “advantage” tends to be greater.

As Rotherham observes:

Rather than the NAEP sample data which has garnered so much attention, Hoxby was able to analyze almost the entire universe of 4th-graders attending charter schools and compare their achievement in reading and math on state assessments to students at the schools they most likely would have otherwise attended. Where 4th-grade data was not available she used 3rd-or 5th-grade data. It’s a much more sophisticated study than the recent AFT report.

I await with bated breath the NYT’s splashy front-pager on this charter school study. UPDATE: That breath will be bated for quite some time.
