Personally I'm not even sure if training works from the employers perspective. There are people who are willing to go the extra mile for whatever reason, and there are who are content just getting by, with some people not even that.

Not to complain, its just an observation. There are people you can point at a problem, and they come back with a great solution a couple days later. I've had a story of a coworker who during her internship was mistaken for someone else working on a totally different speciality and they tasked her with doing something, and after the initial bafflement and fuming, she did it and it was so well done, that the boss came to congratulate her, but was puzzled about why she was on the different side of the org chart.
