It's a charter school with an "open enrollment". Color me suspicious, but I don't see how you get these kinds of results from a random sampling of American students.  There has to be some selection bias here, don't you think?

    Chinese immigrants living in Arizona. That wouldn't surprise me; I have a friend who runs a private tutoring service, and most of her students are Chinese.
