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.

The Texas State Board of Education has given initial approval to a Bible-infused curriculum that would be optional for public schools to adopt for lessons from kindergarten through fifth grade.

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.
