'Derek Black writes that Arizona is a state that funds its schools poorly and inequitably. The kids who need the most get the least. So, instead of fixing its funding system, it has passed an expansive voucher system, which will be most helpful to students in the most affluent districts to underwrite the cost of their private and religious schools. Once again, Arizona stabs its neediest students in the back with underfunded schools. The average student who isn’t disabled will get about $4,400 a year, but some get much more.” The funding mechanism and its expected cost to the state is murky. “The original Arizona plan was estimated to cost the state general fund at least $24 million.” Now, a revised plan and estimate are supposed to save the state $3.4 million by 2022.What is clear, however, is that Arizona’s per pupil funding for public schools currently ranks 47 out of 50 states.'
