The study you reference is only of charter schools in one state. Education policy is decided at the state and local level and varies greatly between states and sometimes even between localities within a state. There is no reason to believe the findings in Louisiana extend beyond it.

The reason is that our similarities are huge, if not complete, throughout the country. Given an imperfect world, finite time, and people needing to do things other than observe themselves so we can play with more data, I think you're in the wrong here. We should assume similarity, try to learn something, and then temper our enthusiasm by recognizing how we may differ. Maybe you have some reason, after reading the study, why your state or region is utterly incompatible with the results?

  Pig and humans share 98% of their DNA. We should just assume drugs will behave the same in both and get rid of those double blind human drug trials. After all there is finite time and people have other things to do.

> There is no reason to believe the findings in Louisiana extend beyond it. There is also no reason to disbelieve that the findings don't extend. You don't get to summarily reject presented evidence that doesn't match your agenda/opinion without evidence to the contrary. There are other studies that show similar results--urban charters are better than public, suburban charters are worse than public. Unfortunately, that demonstrates that the educational facets aren't the deciding factor in educational achievement. You will note that I said "unfortunately". I really wish charters were better than public schools from an educational standpoint so we would have something we could roll out in the public schools. Sadly, most of the "gains" from charters are from student selection. There have been lots of attempts to be better than the public school system. None of them have reliably worked, yet. The Gates foundation hasn't coughed up anything better, either, without expending vastly more money than we are willing to.
