K-12

1. In the U.S. education system, the years from kindergarten to 12th grade. In other words, the years before college.
    
2. In the John Cusack movie Better Off Dead..., a mountain which presents a dangerous challenge to skiers.

A really disheartening designation under which twelth graders are lumped into the same designation as kindergarteners. As in, the book on the school librarian's desk, listing educational supplies for grades K-12. Does a twelth grader need the librarian to go purchase more picture books? As in, the censorware which screens out content "objectionable" to students in grades K-12. Should the twelth grader not see web sites about the holocaust? etc.
