As far as I know it, Quebecers have better public education when compared to Oklahoma. Texas may be closer; I don't know for Maryland.
However, Quebecers are somehow (and somewhat) advantaged because they don't have to go through anything like NCLB. I wouldn't be surprised some people in states neighboring Quebec or other Canadian provinces would rather go to Canadian schools instead.
Remember, in educational matters, Quebec acts like a sovereign nation.
Only Quebec is a lot more distinct compared to other provinces' education, even if they each act as sovereign nations in regard to educational matters.
Honestly, I don't see much difference between an anglophone province and another anglophone province (even if these differences are often subtle.)
