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.

Texas education officials voted narrowly to offer preliminary approval on Tuesday for a new curriculum that includes Bible lessons for children starting in kindergarten, part of a growing effort in the state and elsewhere to bring Christian principles to public schools.
