Here is the wrong question: given that charters + vouchers only serve around 5% of students in the country, how can we fix school districts?
Here is the right question: is it more likely that (a) we can fix school districts or (b) scale effective charters + vouchers to serve the vast majority of students in this country?
Here is what I do know: if you don’t ask the right question, you’re odds of getting the right answer will decrease, perhaps to zero.
Here is what I don’t know: the answer to the right question.
No one does.
I believe both data and theory point to (b) being the right answer.
But, again, no one knows.
