GALLATIN, Tenn. (AP) — Tennessee Gov. Bill Lee conceded defeat Monday in his push to enact universal school vouchers this year, acknowledging there was not a “path forward” after months of Republican infighting.

It’s a blow to school choice advocates who had hoped to add Tennessee to the growing list of states drastically expanding voucher programs with little to no income limits.

“I’m disappointed for the families that were hopeful that their child might have the opportunity to choose the right path educationally,” Lee, a Republican, told reporters. “There is broad agreement that this needs to be done. I feel confident it will be, but we couldn’t put the final pieces together this year.”

According to the National Education Association, the largest U.S. teachers union, 11 states have adopted universal school voucher laws. Supporters argue that doing so gives students in low-performing schools a way out and stress that vouchers give parents more control over what their children are taught. Critics counter that whether students who change schools with the use of taxpayer money achieve better educational outcomes is in dispute.
