I haven't read any of the responses, so parson me if I'm merely repeating an earlier point.

Have you ever gone through job training, where they send you out to train you up on something? I've been to more than one two week course that was 8 hours a day. They are always information packed and somewhat extensive, yet each time, I find myself digesting and discarding 80-90% of what was taught in the course. This is significant because it's not like I took a CPR course, then went to my job as an accountant. This is training specific to the job, then continuing to use that same skill set everyday on the job. As always, training and actual are very different, and the real skull comes from doing.

Requiring additional training will only serve as a waste of money for the public, and creating yet another government protected and subsidized retail market. Ask a friend who has gotten a DUI what a shit show circus all the required classes and drug tests they have to go through.

Bad idea all around.
