If the author and all co-authors vote for House Bill 3, it would pass the lower chamber. The controversial program, also called school choice, would use public money to pay for children’s private school tuition.

The 75 co-sponsors plus the bill’s author would provide enough votes to pass Gov. Abbott’s top priority measure in the 150-seat House.

The General Assembly’s two chambers have each passed their own version of an educational scholarship account bill that would allow families to use state money for private schools. The different proposals means lawmakers appear to be headed to a conference committee to work out the differences.

Families participating in the program could receive about 85% of the amount public schools collect for each attending student from state and local sources.
