Why is this only for high school seniors and college students?

The reason that this is targeted for high school seniors and college students is because they are preparing to step out of the safety and protection of their homes and youth groups into a hostile environment. They tend to be more serious about learning this information. The program is written on a college level so it would be difficult for the younger students to understand the concepts of the Christian worldview. This class is designed to prepare the student how to respond to professors and others that they will specifically meet on the college campus. It points toward the pressure that they will face to give in to other worldviews presented to them on their campuses, in the workplace or the mission field.
