A new study of North Carolina public schools finds that black students in charter schools are more likely to have black teachers than their regular public school counterparts, and that the positive effect of “teacher/student racial match” on the test scores of black students is more pronounced in charter than in regular public schools.
Like most good analyses of charter and regular public schools, this report, written by economist Seth Gershenson and published by the Fordham Institute, is an opportunity to learn from the comparison between the charter and regular public school sectors. For instance, the fact that the “match effect,” which is fairly well-established in the literature (e.g., Dee 2005), is stronger in charter schools is fascinating, though a well-informed discussion of the reasons why this may be the case is well outside of my rather modest wheelhouse (there are some possibilities mentioned in the paper’s conclusion).
I’d actually like to focus briefly on the first finding – that teacher/student racial match is more common for black charter school students. This is the descriptive and arguably less interesting part of the analysis, but it struck me because, like the paper's main finding about the magnitude of the "match effect," it too raises policy-relevant questions, in this case about why teacher diversity might vary between sectors.
