Experts say Trump stands a good chance of winning a tax break for programs that help pay for private tuition. That approach would not steer federal dollars directly to private schools but would still amount to a significant development in a decades-long fight over education.

The curriculum—designed by the state’s public education agency—would allow teachings from the Bible such as the Golden Rule and lessons from books such as Genesis into classrooms. Under the plan, it would be optional for schools to adopt the curriculum though they would receive additional funding if they did so.

Texas public schools could use teachings from the Bible in lessons as an option for students from kindergarten through fifth grade under a proposal that drew hours of testimony and follows Republican-led efforts in other states to incorporate more religious teaching into classrooms.
