:cowboy: As a holder of 3 college degrees and various career job changes... :roll: I would say...
The VAST majority of pre-teens, teens, and such haven't a clue as to what they want to do "the rest of their life". Stuff happens. Goals and dreams change.
For a school to "require" that 13 yo's (and related) decide their curricula for the next 4 years is assinine, ludicrous, etc. Granted, the Administration wants to know how to budget and plan for rooms, textbooks, teachers, class size, etc. However, I seriously doubt that 95% or kids this young haven't a clue as to their primary career aspirations. Oftentimes, the "career selection" is a product of the parents trying to live vicariously through their kids...I know mine did...they were SO wrong in many ways.
There ARE career "clues", on the other hand. Is the kid academically or vocationally inclined? Is he/she better with his/her hands and practical things or with a very high level of "intellectual" inquiry? How have their grades been up to this point in various subjects (an indicator of basic interests)? Are they logically inclined (Left Brain) or artistically inclined (Right Brain)? Are they obsessed with sports things (or) with academic, scientific, research things? Do they prefer to work with people, animals, or things? Are they more inclined to be involved in realistic things or fantasy related things? Are their interests in the realm of current technology and issues as well as global predictions for the next 5, 10, etc. years? The list and clues go on and on...
