Generally, it is to expand the horizons of young people by introducing knowledge, facts, and moral virtues that hopefully will increase wisdom, ethical behavior, and skill levels for the good of the individual and for the good of society as a whole. For some this may mean continuing their education in a formal higher education format. For some it may mean using the skills, wisdom, and virtues learned in a setting that does not needs require formal higher education. No one is better than the other, both have value.
