IT Trainer

Clarifications

to be good at anything requires knowledge and experience, typically gained through education and practice.

Not sure either but being a good technician includes education and experience and above all intelligence. I work full-time but teach two nights a week at a vocational school as a computer networking instructor. There are also teachers working at school full-time, and there's a large difference between those part-time teachers who work full-time in the field and those who don't work in the field. Teachers who can bring knowledge gained from the real world are far more valuable than those who can't, whose knowledge is strictly from a book. All teachers should have some real world experience. Otherwise, their knowledge is unvalidated and not tried and true through experience in the field.
