Look at it this way...

So, remember that CREDO report that came out and is quoted by both sides of the charter school argument.  Here is one more in favor of charter schools.  So, let's say that 37% of charter schools are terrible.  Let's either close them or give them a year or two to improve (unless they've already been warned).  That leaves 63% about the same or better than their local schools.

There are a couple of things demonstrated, at least it seems so to me.  First, one of the criticisms of charter schools is that they do not always hire certified teachers and they most often do not have unions.  So, it seems that this is evidence that union teachers and certified teachers are not a necessary component to a decent education.

Second, charter schools operate on smaller budgets and often in makeshift facilities, not in nice buildings or with all of the frills of traditional public schools.  I realize that not all traditional public schools are nice or have frills, but many do, especially in newer areas or suburbs.  It seems to me that charter schools give evidence that a decent education can be had for less money and without building new buildings or at least the best new buildings.

This many not mean that charter schools should exist.  It does seem to demonstrate that more money and more licensed teachers is not the answer to education reform.
