I've written appraisal courses before, and one thing I can tell you is that its not that easy to write appraisal problems that include more than a couple of significant variables without the "datapoints" looking contrived and overly-simplified. If during a real world assignment you'd be looking at 30 different datapoints in order to get the 10 possibles and 5-6 comparables, each one of the 30 have to be developed enough to be able to either fit or not fit your solution. That's what it would take for an "experience" to mimic a live assignment. Rinse and repeat for maybe 200 such PAREA assignments that would cover a broad swath of different types of appraisal problems and that would be quite the undertaking. The report writing for 200 appraisals will comprise some of those experience hours, so somebody is going to have to read those and provide feedback.
There aren't any shortcuts with live assignments that we perform out in the wild. That's an uncontrolled environment, and it occasionally includes people lying to appraisers about what is/what isn't. Out in the wild, outliers are common in almost all assignments. In order for a PAREA course to mimic those conditions the range of different types of appraisal problems and the specifics of each of the data points that comprise the database for those appraisal problems would need to be a lot more messy and inconclusive than the neatly configured examples that are commonly used in the instructional texts.
Just as an example, if an appraiser covers 8 or 10 or 20 county or municipal jurisdictions, that's how many zoning codes and zoning maps they would need to find, query and interpret over the course of a year. If a PAREA program is being built to mimic that experience and competency it would have to include that level of detail in their materials AND provide a way for the appraiser to access and use that material on their own, without that info just being given to them as normally occurs in a contrived word problem. Same with MLS databases. Same with pics of every datapoint in those databases because those pics are part of the info we analyze during the course of an assignment.
I contemplated building virtual towns, comprised of different property types, size, age and quality neighborhoods, different sized lots, different zoning - the works. Then build a public records database and a separate MLS database (because the two don't always match up IRL). Create the complex world first and then give the student an address to one of the datapoints to proceed on their own. No prompts, no tips, no EASY button. Figure it out, boy, and don't ask for help unless you run into a dead end. And BTW, if your solution sux then you can expect an ROV or a stip from your client. Heck, even if your solution doesn't sux you'll still get ROVs telling you that you "missed" these comps.
If you want to be the man then you gots to be the man. So to speak.
