Hi Brenda,
A career choice needs to be informed, meaningful and realistic. The informed means the students know about the career, meaningful means they enjoy doing it and get value from it and realistic means they can do it. They have the knowledge and skills required.
Anything you can do to help them experience these three areas as they start to narrow their career choice down is valuable to the students. Guest speakers, job shadowing and practicums are great ways to help them see the "real" part of the career choice they will be making.
