Utah teens (grade 9-12) are already often forced (by parents) into taking a full class period for Mormon learning (called Seminary).

The main reason for this is some countries require formal religious "training" before allowing someone to prosthelytize, so the Mormons start early to ensure kids can go on their "mission" at the fresh age of 18.
