It's almost a sure thing that the Republican-led AZ legislature will try to add more funding and more students to our two private school voucher systems this year. They try it every year, and they usually succeed. The only questions are, what will their additions look like, and will they make it to Gov. Ducey's desk?
The Arizona School Boards Association has put together a three minute primer on the state's two voucher systems: Student Tuition Organizations (aka backdoor vouchers) and Empowerment Scholarship Accounts (aka Educational Savings Accounts, also aka Vouchers on Steroids). The information in the video is pretty accurate, though it's possible to quibble around the edges. As for its anti-voucher slant, which I agree with, you don't have to agree to learn more about how the two programs work.
Remember, vouchers have nothing to do with charters. Charters are publicly-funded, privately run schools which get more-or-less the same amount of tax dollars per student as district schools. Vouchers are about using tax dollars to pay for tuition to private schools.
