Texas education officials are expected to vote on Monday on whether to approve a new elementary-school curriculum that infuses teachings on the Bible into reading and language arts lessons.

The optional curriculum, one of most sweeping efforts in recent years to bring a Christian perspective to more students, would test the limits of religious instruction in public education.

It could also become a model for other states and for the administration of President-elect Donald J. Trump, who has promised to champion the conservative Christian movement in his second presidential term.

In the ascendant but highly contested push to expand the role of religion in public life, Texas has emerged as a leader. It was the first state to allow public schools to hire religious chaplains as school counselors, and the Republican-controlled legislature is expected to renew its attempts to require public-school classrooms to display the Ten Commandments.

The new curriculum, which covers kindergarten through fifth grade, would be optional, although school districts would receive a financial incentive to adopt it. The Texas State Board of Education sets standards for what students must be taught and approves a selection of curriculums, and individual schools and school districts choose which ones they will teach.

Texas has about 2.3 million public-school students in kindergarten through fifth grade who could be taught the new curriculum.
