Without context for the numbers or their significance, this seems like another "AAH! Education Panic!" bit of discourse.
Pretty obvious the big hit happened during COVID and now we're in a long hangover period. But absent more meat on the bone than "Number was 500 and now it's 460". What's the useful takeaway from this information? Other than to just express more generic Doomerist sentiments in the comments? Hard to say.
Also might be worth asking, if the numbers had gone up instead of down, would anyone here be celebrating? Would it have even been posted? Case in point:
The Test-Optional Paradox: Why Published SAT Scores Keep Rising Even as Fewer Students Submit Them
Is this something we should be happy about or sad about?
