I did some math

And about that article, I am not arguing for school choice, just showing a list of the facts.
They may or may not be true, but if they are... With proficiency per dollar spending DC is still at the
bottom for proficiency rates.
The Massholes slip (it's humbling) to second in reading/dollar behind Kentucky and
fifth (oops!) in math/dollar, with Minnesota taking the lead.

In case you were wondering.

I love being from the smartest state in the US

Guess the MCAS were good for something. Massachusetts has the highest proficiency rate on the NAEP tests.
DC has the lowest (and they spend over close to twice as much per student).

PS Props to Minnesota for coming close.
