Is anyone else reading the results?
England has done well again - huge improvement since 2009 though there does seem to have been a bit of a drop since COVID. Frustrated though I am with this wretched government, improving educational attainment is one thing that they do actually appear to have achieved during this period. England is notable for the success of both first and second generation immigrants, very different from most European countries.
Scotland and Wales are continuing to sink. Whatever they are doing over there isn’t working. Oz isn’t doing too well either. The US likewise.
China’s scores (they tested students from four provinces last time) don’t seem to have been reported. Perhaps there are doubts about the veracity of the data (wouldn’t surprise me).
