As in so many other professions, it is a craft that needs to be learned from the ground up; it is the combination that adds to the understanding, the science part is a portion and the art is a portion, both are needed to provide an end result.
What I find most interesting is during my time within the industry, there was a reasoning for gaining greater education, a goal to strive for, since 08 that has been abolished. Pre 08, the funny money bandwagon was on a roll, yep the appraisals were as bad as the loans processed at the time; except a few who believed in what they were producing. That piece alone cannot be taught in High School or College, you need to have the right stuff, (IE: GH - our remaining economic life our adherence to the ETHICS RULE) and anyone can avoid that, but that's what puts the tire to the road. Education or not; a good portion of the problem (so-called shortage) Lenders would not accept a Trainee....Why ? you can't stop progress and then claim 100 reasons why it should be changed, and to avoid a part of the process (Boots On The Ground work) is a huge mistake. Training & Education go hand in glove, there is no substitute I can think of.
How would you like to have a surgeon fresh out of College with no Training, work on You ??
A carpenter build your House right out of school, no Training ?
A Banker become the CEO right out of College ? Anyone ever seen that happen ??
