Lots of anguish in various countries media about #PISA scores which seem to have slumped after the pandemic (though the economist rightly notes they were on a long slow decline before too).
What I really want to read though is a thorough statistical analysis - what do the numbers actually mean? What's the uncertainty range? What is the spread within the numbers? Is #PISA22 even measuring what we think it is + just how comparable across countries are the test conditions?
Any takers?
