James McGovern asks a question about corporate education classes:

Have you ever noticed that the vast majority of educational courses targeted at corporate America are introductory? Have you asked yourself why aren't there more courses that teach advanced concepts? We all understand that advanced concepts logically depend on simpler concepts but thinking should stop there. Humans don't learn using predicate logic, so advanced concepts can be taught even to children, so as long as the person teaching them has some level of competency.

Back in the old days, when I was a VW instructor for ParcPlace, we faced exactly this quandary. Customers would ask us about advanced material, since our public offerings were mostly introductory. There was a reason for that, and it was based on the actual behavior of corporate customers.

When we gave an advanced course, companies would send people to it who weren't prepared. Happened every time I was involved in an advanced course, even when sales and services management made a point of telling the customer that the material assumed a certain level of pre-existing knowledge. We would show up, and find that half (sometimes more) of the class was completely unready for the material - and that made the entire thing unfair to both the prepared students and the unprepared ones - neither group really got the instruction they needed.

I suspect that we weren't unique in this regard - ask around the professional training ranks, and I'd guess that they would all say the same thing.
