It's funny how the plummeting ranking in the PISA league tables is brushed off as seemingly irrelevant though, wouldn't you say?
Bruce - there is a very good argument to be made that the results are getting worse
because of misguided experiments.
British secondary education policy was relatively stable up until 1997 - its since then that we have had Academies, Free Schools, deskilled teachers, increased PFI spending, gradually weakened LEAs, significant changes to the National Curriculum and then tertiary changes like tuition fees and the removal of the maintenance grant which have probably had some kind of negative effect as well.
As you have pointed out, the results are worse and we spend much more to get them.
