This should be abundantly obvious, but I'll explain anyway. Let's first clarify what you mean by "holistic." What is sounds like you're saying is that UW looks at more personal factors (and puts more weight on those factors) than other schools, clearly with the connotation that it results in selecting more "well-rounded" applicants. This comes off as incredibly arrogant and elitist. The fact that you can't backup the statement with any credible evidence makes it even worse.
Okay?
And at the same time you could also say that having more "well rounded" applicants results in having applicants with lower stats, which by your same line of reasoning means they are selecting "dumber" applicants than other schools which is also degrading.
What you're saying sounds just as arrogant and elitist depending on the person's point of view.
Furthermore, most people would agree that having an institution not give preference to certain undergrads based on prestige or connections and admitting more applicants with real world experience is the opposite of arrogant and elitist.
Correct. And furthermore, there will be substantial differences in selection criteria within an institution depending on who first picks up your application - perhaps even more than the differences between institutions. However, you still haven't posted any credible evidence to suggest that UW's method differs in any significant way from any other institution. Clearly you want to believe this, but that doesn't make it true.
Possibly, however some adcoms use a standardized rubric to evaluate applications, while at other schools its entirely up to each reviewer. The inter-adcom variability differs from school to school.
Most of this is patently false. Every school looks favorably on working while attending school. Every school also has a panel of reviewers.
As far as UW being unique in its use of a weighted GPA, not giving preference to certain undergrads, or having a lower screening bar: I seriously doubt it, but would love to see your evidence.
Looking favorably at working during undergrad and taking it into account while evaluating your GPA are 2 different things.
I know for a fact that multiple schools only have 1 reviewer look at each application before deciding on interviews
(Georgetown is one example).
UW clearly states their admissions criteria on their website (not just the FAQs) and during admissions workshops they give to premeds every year.
Look, Im not saying admissions is some black and white endeavor between schools whereby some schools are holistic and others are not. Nor am I saying its as simplistic as you're suggesting. But, you can't seriously think that schools like WashU give the same weight to ECs as schools like Colorado and they every school essentially evaluates applications using the same criteria.
If what you're saying were true nearly all med schools would have almost identical student bodies (based on average stats, ECs, entering age, type of undergrad, percentage of students w/ grad degrees, percentage of non-trads, etc…) which is not the case.
