Officials in Texas are set to vote Tuesday on a controversial new public school curriculum that incorporates Christian lessons from the Bible as early as kindergarten while putting less focus on other faiths.

Texas education officials on Tuesday voted to support an optional elementary-school curriculum that would include lessons based on the Bible, which opponents say unfairly promotes Christian beliefs in public schools.

At a meeting of the Texas State Board of Education on Monday, educators, parents, and religious advocates offered testimony for and against the proposal, which would allow Bible teachings—such as the Golden Rule and lessons from books like Genesis—to be included in classrooms.
