Officials in Texas are set to vote this week 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.

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