I think there are still some states (or at least there used to be) that allow you to be a lawyer if you pass the bar exam - no college. Seems logical to me. Make the test as tough as it needs to be and those that cant pass do not enter. Fair. Simple. For appraisers there is another element in play. Experience. There is something that happens after an appraiser has seen a certain number of houses and analyzed a certain number of sales. This is in my opinion the most significant piece of the competency puzzle.
In California, you can take the BAR with no college. Pretty much apprenticeship for several years if I recall correctly.
Can you imagine how much more competent that lawyer would be compared to a kid who just got out of law school?
