The entities and profiteers found out how to exploit the gaping flaw of USPAP, which is that in USPAP, an inspection alone (without an opinion or analysis ) may not be considered part of appraisal race. IT should be, an inspection done for APPRAISAL PURPOSES is part of appraisal practice. But USPAP allowed the profession to be flooded with nonlicensed people for one of the key components of an appraisal - the in personal inspection of the property- call it a PDC till the cows come home, it is a proxy for an inspection.
I can't imagine this happening in any other field. For example, lawyers use paralegals who are licensed, personally selected, supervised and have extensive training. ( like an appraisal trainee s ). Can you imagine some glitch in the legal profession opening up the doors to replace paralegals with fast-trained gig workers to handle "legal data?" ( apply that to any profession )
