Hi FirmComplaint321,
Historically, most Business Schools have not put too much of an emphasis on an Applicant's AWA Score (in simple terms, as long as you scored at least a 4.0 out of 6.0 on the AWA, you were 'fine'; anything lower than a 4.0 could potentially be viewed as problematic).
At this point, a certain number of Applicant's are taking the At-home GMAT - which does not include an AWA section - but the 'conclusion' that you're offering (re: the AWA suddenly won't matter) is dubious. To start, there's no way of knowing how many people will actually APPLY with an At-home GMAT Score going forward - and of those who do, it's unclear whether the Schools will look to measure their AWA 'skills' in some other way (such as asking those Applicants to write an additional, (possibly timed) essay as part of the application process). If two fairly 'identical' applicants applied to the same School and one had an AWA while the other did not - and the School had just one 'spot' left - there's a legitimate question as to how the School might 'break the tie...' Maybe the AWA would matter (but to be fair, maybe it wouldn't).
Second, while the immediate impact of Covid-19 on the Business School application process is significant, it's likely that that will NOT be the case within a relatively near timeframe (re: within the next year or so). It's possible that the At-home GMAT won't be offered as a testing option at some point in the near future - at which point, GMATers will go back to the standard testing format (which will include the AWA section).
If you are planning to apply to Business School this cycle, then the issue about whether having an AWA Score or not is probably moot. Beyond this year though, there's simply no way of knowing how the application process might change in the years to come (and that includes assessing how much an AWA Score might impact your overall chances of getting into the Schools that you apply to).
GMAT assassins aren't born, they're made,
