The most erudite discussion of Arizona charter schools you will ever hear

Lisa Graham Keegan is a former Arizona superintendant of public instruction; she is also probably the most prominent advocate of charter schools in the state.

Julie Erfle is a blogger and journalist who has written a scathing critique of how the performance of charter schools is often judged.

In a nutshell, Erfle argues, if you hand-select the best students, they do exceptionally well.

Not surprisingly, Graham Keegan has a different take.

Civil? Always. Highly informed. Thoughtful. Tune in; you might learn something.
