What teachers unions don't want you to see: spending vs. test results

How come no one ever compares spending-per-student with standardized test results? I'm kinda surprised that the NEA and the other teacher's unions don't publicize these stats (heh).

I put together a workbook that matches up these variables and discovered some interesting insights. For instance: the District of Columbia spends the most (by far) and has the worst results (by far).

Now you can see why the anti-voucher teachers unions hate standardized testing. You know, the type of thing mandated by No Child Left Behind.
