Here's a summary of the arguments, and the current movement towards vouchers.
Proponents say tax-credit and voucher programs offer families a way to escape failing public schools. But critics warn that by drawing money away from public schools, such programs weaken a system left vulnerable after years of crippling state budget cuts — while showing little evidence that students actually benefit.
“This movement is doing more than threaten the core of our traditional public school system,” said Timothy Ogle, executive director of the Arizona School Boards Association. “It’s pushing a national policy agenda embraced by conservatives across states that are receptive to conservative ideas.”Currently, 17 states offer 33 programs that allow parents to use taxpayer money to send their children to private schools, according to the American Federation for Children, a nonprofit advocate for school vouchers and tax-credit scholarship programs that give individuals or corporations tax reductions if they donate to state-run scholarship funds.
