Fisking the fisker

I’m not blogging much at the moment, but I still abide by my golden rule of blogging:  if I happen to come across some twat misusing PISA results in defence of Gove, then I will always make a point of calling her/him out, if I can be arsed.

So there’s a total twat, Toby Young by name, misusing PISA results in defence of Gove, and I can be arsed.

Young says, in a piece ‘fisking’ the apparently “hysterical” Suzanne Moore*:

Ah. Here we go. Her [Moore's] views are “evidence-based”, Gove’s are “ideological”. Odd line of argument for a former employee of Marxism Today to pursue, but there it is. In fact, there’s plenty of evidence to support Gove’s policies. Here’s evidence that standards fell during Labour’s 13 years in office. Here’s evidence that free schools have raised standards in Sweden. Here’s evidence that increasing school choice has raised standards in England. Here’s evidence that the academies programme is raising standards in England.

The first link is to the wikipedia entry on the Programme for International Student Assessment (PISA).

And this is what the Chair of the UK Statistics Authority had to say about the blatant misuse of PISA data by Ofsted and the DfE:

While I understand that some users of these data would like to make comparisons between the first PISA study in 2000 and the most recent in 2009, the weaknesses relating to the response-rate standard in earlier studies should not be ignored. The validity of comparisons of national rankings as a result of an increase in the number of countries covered by the PISA study, and the degrees of uncertainty in country scores attributed to sampling and measurement error are also important in this regard.

That is, Young is totally and utterly wrong**.  More on why he’s wrong here***, here, here and, just for completeness sake, the National Foundation for Educational Research review of the PISA 2009 study:

England’s performance in 2009 does not differ greatly from that in the last Pisa survey in 2006.

*  Readers may wish to note James Delingpole’s delightful metaphor on twitter for Young’s attempted fisking of the “hysterical” Moore.   I can’t remember where I put it though.  Anyway, it’s bound to cause a twitterstorm so you may see it before I see it again.

**  Of course, it’s not just that he’s deliberately misusing the PISA data.  His logic is also utterly at sea.  Even valid evidence that England may have fallen down the international ranking wouldn’t be proof that standards have fallen.  It might be as easily explained by other countries getting better (oh, and the huge increase in the number of countries in the rankings).

***  , I note that I asked, in this post about the Chair of the UK Statistics Authority’s October ’12 letter:

Will they continue to peddle the same untruths, secure in the knowledge that the “plummeting down the international league tables” is now well entrenched as a result of lies to date, and much more likely to gain press coverage than a letter from the UK Statistics Authority?

I think we now know the answer.
