After nearly 30 years of stalled efforts, Texas is in line to become the largest state with a universal private school choice program. The Republican-controlled state House of Representatives approved a $1 billion measure Thursday—which gets the legislation closer than ever to the governor’s desk.

In a seismic shift for Texas education that could have ramifications for decades, the state House signed off on a plan early Thursday to allow parents to use state dollars to pay for their children’s private school education.

The Texas House approved a $1 billion school choice voucher program which would allow roughly 100,000 families to use public school dollars on private and home schooling.
