The thing is, it works like this in certain countries. At least in Switzerland and Germany it is possible to make an apprenticeship as a programmer. This means there is a structured path for the vocational education that must meet certain regulatory criteria. Normally this takes 3-4 years to finish and includes both, working at a company as well as visiting vocational school. College is often done after finishing one’s apprenticeship to broaden the understanding of more complex or advanced topics like security, architecture, project management, advanced math etc.

I don’t understand why this system is not more common in other places. Programming (not CS) is very much like a craft and to large degrees can be taught as/similar to one.
