> That's funny, because New York and Arizona perform about the same in the NAEP assessment. Clearly, New York has a lot to learn from Arizona, if it can achieve the same results with quarter of the NY's spending.

Given how much of school costs are labor costs, the main thing Arizona is probably doing “right” to produce those efficiencies is hiring people who live in Arizona.

It's not likely that New York can really learn much from that.
