No where is this more evident that in chemistry/analytical laboratory situations.
When I graduated I went to work for a company in southern Michigan. We hired GOOD high school graduates for the technician positions in the lab. By the time I retired, we would not look at a high school graduate.
There were two reasons. One the high school grand could pass the standardized test but did not have the knowledge to be trained for the technicians positions.
The second reason was that from a Government Regulatory aspect it was much easier to convince an regulatory person that the person had the proper training if we started with a person with a BS or MS degree, and then trained; them rather than saying we started with a high school graduate.
Did it make any difference, I have tried to train people that had a college "Education" that could not comprehend what they read, at least could not translate what they read in the steps necessary to do the job.
