If you make the grade for college, you're sent to trade school or an apprenticeship program instead of high school.
I still remember kids (high school age) on a scaffold eating a sandwich and a flip top beer. Masonry or brick laying was big back then.
I think they have a real formal trades arrangement in Europe too, maybe especially in Germany. I think when they use words like "Journeyman" it has a little more meaning than when we say it.
