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.
