The goal should be to cover all possible outcomes. Employment for those inclined be it industrial labor or business, college prep, entrepreneurship. Industrial arts classes relate to jobs in manufacturing. Computer classes, business classes relate to jobs in business. Advanced English (communication), science, math relate to those about to enter college. Business classes et.al. relate to those wishing to eventually start a business. There are classes in the arts, opportunities for experience in the theater, that can acquaint the student with careers in the arts. Many other classes, seek to make the student prepared for the process of living.
This is the American system in general. It seems to cover all the post-high school possibilities. The classes a student takes, other than those required by the system, are the choices of the student and/or his parents. Is there something that I have missed?
I had not realized that you were referring to the UK before reading your current post. What is: "GCSE's"?
In the most part it seems to be the goal. However, the student must have the means for making a living for his benefit. The school system would fail if it graduated people who did not have the requisite skills to be employable (read, write, math).
Yes, here in the U.S. it is stressed by the teachers also because potential employers state that is the most desirable characteristic looked for in a candidate for employment. There seems to be no market for persons who are not willing to work in an enthusiastic manner. Should schools convey the idea to the students that lack-luster performance is going to be acceptable to their potential employers?
