School districts serving more than two million elementary school children would be able to adopt a curriculum that draws on the Bible.

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.

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.
