I'm a little cautious about this, Cory. The data is horrendously complex to interpret. However, as far as I can see Sweden were not number one in the international educational league tables. In 2000, when the OECD PISA study first appeared, it was 9th in reading, 15th in maths and 10th in science. In 2006 it was 10th in reading, 21st in maths and 22nd in science, so it remained pretty static in reading but fell back in the other two. However, most of the fall has been due to the fact that more countries are now taking part in the tests that produce these league tables, with many of the new arrivals going straight into the top 10. Over the period these tables have been in existence the UK has dropped further than Sweden. In 2000 we were 7th, 8th and 4th but by 2006 we had fallen to 17th, 24th and 14th. So from being ahead of Sweden in all three subject areas, we are now behind Sweden in two.
A recent study by the Unversity of Gothenburg found that, in as much as there has been a decline, the free schools are not the reason. Many other things are more important including housing segregation and the introduction of the current national curriculum which led to increased use of independent learning and reduced the use of teacher-led instruction. This national curriculum is seen as chiefly to blame for the fall in maths and science.
The evidence available suggests that the free schools in Sweden perform better than municipal schools and that the presence of free schools in an area results in improved performance by the local municipal schools.
There are, of course, plenty of reasons to believe that the free schools in this country may not succeed. But the suggestion they have failed in Sweden is at best unproven.
