What does PISA say about UK 15-year-olds?

Back to FAQs

The Programme for International Student Assessment (PISA) has taken place every three years since 2000.  The figures for the UK in 2000 showed UK pupils doing well.  But the OECD, who runs the tests, later found the figures were faulty and withdrew them.   The OECD did not accept figures for the UK in 2003 because of sampling problems.  The only reliable figures for the UK are for 2006, 2009 and 2012.

PISA 2009

Between 2006 and 2009 there was a relative fall in ranking from 17th to 25th in reading, 23rd to 28th for maths, and 14th to 17th in 2009 for science. But more countries took part in the 2009 tests – 65 compared with 58 in 2006. However, there is little statistical difference between the 2006 and 2009 scores.

In the 2009 PISA tests, UK pupils were at the OECD average for reading and maths, and above the OECD average for Science

In December 2010, when the 2009 PISA results were published, the Government and most of the media ignored the OECD warning not to compare the 2009 results with the faulty 2000 figures.  This led to the "plummeting down league tables" myth.  In October 2012, the UK Statistics Authority expressed concern about the way the Department of Education (DfE) had used PISA statistics.  There has, however, been no apology from either the DfE or newspaper editors.  The faulty figures continue to be used to portray state education in England as being in a pitiful state.  Tory MPs Chris Skidmore and Prit Platel made the false comparison after the UK Statistics Watchdog had warned against their use.  And the Confederation of British Industry  (CBI) published the 2000 figures in a graph in its 2013 Annual Report. 

Programme for International Student Assessment (PISA) 2012

The results showed a slight improvement in the performance of UK 15 year-olds. However, it was statistically insignificant. Performance has remained static. UK pupils still performed at the OECD average in reading and maths, and above the OECD average in science in PISA 2013.
